我只想在我的
DataGrid
最左边的列中显示行号。有什么属性可以做到这一点吗？

using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}
请记住，这不是我的表的主键。我不希望列排序时这些行号随行移动。我基本上想要一个连续的计数。它甚至不需要有头。

一种方法是将它们添加到DataGrid的LoadingRow事件中

<DataGrid Name="DataGrid" LoadingRow="DataGrid_LoadingRow" ...

void DataGrid_LoadingRow(object sender, DataGridRowEventArgs e)
{
    e.Row.Header = (e.Row.GetIndex()).ToString(); 
}

using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}

添加有关Fredrik Hedblad答案的简短信息


<DataGrid Name="DataGrid" LoadingRow="DataGrid_LoadingRow" ...

void DataGrid_LoadingRow(object sender, DataGridRowEventArgs e)
{
    e.Row.Header = (e.Row.GetIndex()+1).ToString(); 
}



using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}



为了增加对这个问题的讨论。。。（我花了太多时间才弄明白！）


using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}


您需要在datagrid上将EnableRowVirtualization设置为False，以防止行排序中出现错误：


EnableRowVirtualization="False"



using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}



默认情况下，
EnableRowVirtualization
属性设置为
true
。当
EnableRowVirtualization
属性设置为true时，DataGrid不会为绑定数据源中的每个数据项实例化
DataGridRow
对象。相反，DataGrid只在需要时创建DataGridRow对象，并尽可能地重用它们
 使用附加属性，完整源代码


using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}



Xaml：


using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}



这是个老问题，但我想和大家分享一些东西。我有一个类似的问题，我所需要的只是一个简单的
行标题
行数，弗雷德里克·赫布拉德的答案几乎完全解决了我的问题


using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}


虽然这很好：


using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}



<DataGrid Name="DataGrid" LoadingRow="DataGrid_LoadingRow" ...

void DataGrid_LoadingRow(object sender, DataGridRowEventArgs e)
{
    e.Row.Header = (e.Row.GetIndex()).ToString(); 
}



这为我解决了去同步化的计算问题，因为刷新项会再次调用
DataGrig\u LoadingRow
。
如果数据网格将其项源绑定到集合，请将数据网格的AlternationCount属性绑定到集合的count属性，或到DataGrid的Items.Count属性，如下所示：


using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}



<DataGrid ItemsSource="{Binding MyObservableCollection}" AlternationCount="{Binding MyObservableCollection.Count}" />






或：


using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}






两者都应该有效


using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}


然后，假设对最左边的列使用DataGridTextColumn，则在DataGrid.Columns定义中执行以下操作：


using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}



<DataGrid.Columns>
   <DataGridTextColumn Binding="{Binding AlternationIndex, RelativeSource={RelativeSource AncestorType=DataGridRow}}"
</DataGrid.Columns>





这是另一个答案，为新手或匆忙中的人提供了几乎是复制粘贴的例子（不受鼓励），灵感来源于@GrantA和@Johan Larsson在这篇文章中给出的答案（+许多其他人回答了关于该主题的众多帖子）

        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}

注意（ItemsControl.alternationadex）周围的括号（），如中所警告的


using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}



使用
RowHeaderStyle
进行一些测试后，NGI修复和扩展的样本：


using System.Windows;
using System.Windows.Controls;

public static class Index
{
    private static readonly DependencyPropertyKey OfPropertyKey = DependencyProperty.RegisterAttachedReadOnly(
        "Of",
        typeof(int),
        typeof(Index),
        new PropertyMetadata(-1));

    public static readonly DependencyProperty OfProperty = OfPropertyKey.DependencyProperty;

    public static readonly DependencyProperty InProperty = DependencyProperty.RegisterAttached(
        "In",
        typeof(DataGrid),
        typeof(Index),
        new PropertyMetadata(default(DataGrid), OnInChanged));

    public static void SetOf(this DataGridRow element, int value)
    {
        element.SetValue(OfPropertyKey, value);
    }

    public static int GetOf(this DataGridRow element)
    {
        return (int)element.GetValue(OfProperty);
    }

    public static void SetIn(this DataGridRow element, DataGrid value)
    {
        element.SetValue(InProperty, value);
    }

    public static DataGrid GetIn(this DataGridRow element)
    {
        return (DataGrid)element.GetValue(InProperty);
    }

    private static void OnInChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var row = (DataGridRow)d;
        row.SetOf(row.GetIndex());
    }
}



        <DataGrid EnableRowVirtualization="false" ItemsSource="{Binding ResultView}" AlternationCount="{Binding ResultView.Count}" RowHeaderWidth="10">
            <DataGrid.RowHeaderStyle>

                    <Setter Property="Content" Value="{Binding Path=AlternationIndex, RelativeSource={RelativeSource AncestorType=DataGridRow}}" />
                </Style>
            </DataGrid.RowHeaderStyle>

可能重复的问题可能我理解错了，您想为此单独列一列，还是行标题也可以？
行标题
非常完美，谢谢。如果您使用的是MSSQL Server 2005+，您可以尝试：这会在排序期间移动行号吗？或者在排序过程中也调用了
LoadingRow
，这样可以使行号始终保持有序吗？@VoodooChild:是的，我已经使用过几次了，就我所知，行号总是按照正确的顺序排列，即使是排序、滚动、更改项目资源等，这里的一个人告诉我这对他不起作用。我问他更多的情况，但他没有回答。但对我来说，我从未见过这样做失败的情况：）如果你想从#1开始：
e.Row.Header=（e.Row.GetIndex（）+1.ToString（）确保属性
标题可见性
设置为
全部
或
行
<代码>列
和
无
将不显示该值。例如：
这不适用于虚拟化。如何调整代码以处理虚拟行？如果您已在datagrid中滚动并重新加载集合，这将无法正常工作。在datagrid中滚动到的项目顶部，编号将从0开始。这对我来说很有效，但当我使用鼠标在datagrid上滚动时，索引号会随机更改。如何修复此问题？禁用虚拟化是错误的。。。有没有办法让它与虚拟化一起工作？
