C# 通过编程方式添加DataTemplate和DataGrid WPF的数据绑定问题

我正在尝试以编程方式为DataGrid创建Datatemplate。 我能做到。但我被困在一个位置。DataGrid的绑定不起作用。 我认为绑定存在一些问题。以下是我得到的输出：

图像中的第三列是空的，尽管我已经为该列设置了绑定

以下是XAML文件：

<Window x:Class="NestedListViewDemo.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525" WindowState="Maximized">
    <Grid Name="MainGrid">

<DataGrid x:Name="myDataGrid" AutoGenerateColumns="true" Loaded="myDataGrid_Loaded">
        <DataGrid.Columns>
            <DataGridTemplateColumn x:Name="templatecolumnId" Header="Id" />
            <DataGridTemplateColumn x:Name="templatecolumnName" Header="Name" />
            <DataGridTemplateColumn x:Name="templateColumnInnerTable" Header="InnerTable" />
    </Datagrid.Columns>
</DataGrid>
       </Grid>
</Window>

始终需要为

DataGrid

设置

集合。我对你现有的代码做了一些修改，效果很好。请参阅下面的代码片段

通过添加
AddressClass
的
Collection
来修改您的
AddressClass
。此属性需要与
数据网格
绑定

public class Address
{
    public string Id { get; set; }
    public string Name { get; set; }

    public Address() { }
}

public class AddressClass
{
    public string Id { get; set; }
    public string Name { get; set; }

    public List<Address> Address { get; set; }

    public AddressClass()
    {
        Address = new List<Address>();
    }
    public void AddItems(Address item)
    {
        Id = item.Id;
        Name = item.Name;
        Address.Add(item);
    }
}
public class InnerClass
{
    public string InnerData { get; set; }
}

调用方法的更改

public MainWindow()
{
        InitializeComponent();
        DataGrid innergrid = new DataGrid();

        InnerClass ic = new InnerClass();
        ic.InnerData = "InnerXYZ";
        innergrid.Items.Add(ic);

        Address ac = new Address() { Id = "100",Name ="Vimal" };
        Address ac1 = new Address(){Id ="101", Name= "Vimal 1"};
        AddressClass add = new AddressClass();
        add.AddItems(ac);
        add.AddItems(ac1);
        myDataGrid.Items.Add(add);

        myDataGrid.MinRowHeight = 100;
        myDataGrid.MinColumnWidth = 250;
    }

你为什么要用代码隐藏做这些事？这就是XAML的用途，我只想创建n级嵌套的ListView/DataGrid。级别在运行时决定。因此，我想在代码隐藏中做这件事。非常感谢兄弟。成功了。我很乐意订阅您的博客以获取更新。
public void myDataGrid_Loaded(object sender, EventArgs e)
{
        var dataTemplate = new DataTemplate();
        FrameworkElementFactory tbHolder1 = new FrameworkElementFactory(typeof(Label));
        tbHolder1.SetBinding(Label.ContentProperty, new Binding("Id"));
        dataTemplate.VisualTree = tbHolder1;
        dataTemplate.DataType = typeof(DataGridTemplateColumn);
        templatecolumnId.CellTemplate = dataTemplate;

        dataTemplate = new DataTemplate();
        FrameworkElementFactory tbHolder2 = new FrameworkElementFactory(typeof(TextBlock));
        tbHolder2.SetBinding(TextBlock.TextProperty, new Binding("Name"));
        dataTemplate.VisualTree = tbHolder2;
        dataTemplate.DataType = typeof(DataGridTemplateColumn);
        templatecolumnName.CellTemplate = dataTemplate;

        dataTemplate = new DataTemplate();
        FrameworkElementFactory tbHolder3 = new FrameworkElementFactory(typeof(DataGrid));
        tbHolder3.SetBinding(DataGrid.ItemsSourceProperty, new Binding("Address"));
        tbHolder3.SetValue(DataGrid.AutoGenerateColumnsProperty, true);
        dataTemplate.VisualTree = tbHolder3;
        dataTemplate.DataType = typeof(DataGridTemplateColumn);
        templateColumnInnerTable.CellTemplate = dataTemplate;
    }

public MainWindow()
{
        InitializeComponent();
        DataGrid innergrid = new DataGrid();

        InnerClass ic = new InnerClass();
        ic.InnerData = "InnerXYZ";
        innergrid.Items.Add(ic);

        Address ac = new Address() { Id = "100",Name ="Vimal" };
        Address ac1 = new Address(){Id ="101", Name= "Vimal 1"};
        AddressClass add = new AddressClass();
        add.AddItems(ac);
        add.AddItems(ac1);
        myDataGrid.Items.Add(add);

        myDataGrid.MinRowHeight = 100;
        myDataGrid.MinColumnWidth = 250;
    }
