C# WPF DataGrid-获取鼠标光标所在的行号
我希望获得DataGrid中鼠标光标所在的行号(基本上是在MouseEnter事件上),这样我就可以获得ItemSource也绑定了的DataGridRow项 我对MouseEvent的XAML是C# WPF DataGrid-获取鼠标光标所在的行号,c#,wpf,datagrid,C#,Wpf,Datagrid,我希望获得DataGrid中鼠标光标所在的行号(基本上是在MouseEnter事件上),这样我就可以获得ItemSource也绑定了的DataGridRow项 我对MouseEvent的XAML是 <DataGridTextColumn.ElementStyle> <Style TargetType="{x:Type TextBlock}"> <EventSetter Event="MouseEnter" Handler="Eve
<DataGridTextColumn.ElementStyle>
<Style TargetType="{x:Type TextBlock}">
<EventSetter Event="MouseEnter" Handler="Event"></EventSetter>
<Setter Property="ToolTip" Value="{Binding Property}" />
</Style>
</DataGridTextColumn.ElementStyle>
也许我现在这样做是不可能的,但如果不能用某种方式做到的话,我会感到惊讶
谢谢好的,我在这里找到了答案 不要被文章的标题弄糊涂了 对于我的解决方案,我基本上使用
private void MouseOverEvent(object sender, MouseEventArgs e)
{
DependencyObject dep = (DependencyObject)e.OriginalSource;
// iteratively traverse the visual tree
while ((dep != null) &&
!(dep is DataGridCell) &&
!(dep is DataGridColumnHeader))
{
dep = VisualTreeHelper.GetParent(dep);
}
if (dep == null)
return;
if (dep is DataGridColumnHeader)
{
DataGridColumnHeader columnHeader = dep as DataGridColumnHeader;
// do something
}
if (dep is DataGridCell)
{
DataGridCell cell = dep as DataGridCell;
// navigate further up the tree
while ((dep != null) && !(dep is DataGridRow))
{
dep = VisualTreeHelper.GetParent(dep);
}
DataGridRow row = dep as DataGridRow;
//!!!!!!!!!!!!!* (Look below) !!!!!!!!!!!!!!!!!
}
- 现在您可以使用row.Item和bingo获得自己的对象,它位于正确的行索引上
因此,所有关于使用鼠标原始源代码的内容都会在VisualTree上运行,直到找到正确的元素 如果访问鼠标所在的
DataGridRow
对象,则可以使用以下命令查找其行索引:
这对我有用
<DataGrid x:Name="dataGridView">
<DataGrid.Resources>
<Style TargetType="DataGridRow">
<EventSetter Event="MouseEnter" Handler="Row_MouseEnter"/>
</Style>
</DataGrid.Resources>
</DataGrid>
private void Row_MouseEnter(object sender, MouseEventArgs e)
{
int index = dataGridView.ItemContainerGenerator.IndexFromContainer((DataGridRow)sender);
}
私有无效行\鼠标指针(对象发送器,鼠标指针)
{
int index=dataGridView.ItemContainerGenerator.IndexFromContainer((DataGridRow)发送方);
}
在我的一个应用程序中,我需要鼠标下方的DataGridRow来突出显示它。
每个单元格都有一个数据模板
<DataTemplate x:Key="templateCenter">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" Margin="10 0 10 0">
<Image Source="{StaticResource Back}" Width="15" Height="15"/>
<Image Source="{StaticResource ListMove}" Width="35" Height="35"/>
<Image Source="{StaticResource Forward}" Width="15" Height="15"/>
</StackPanel>
</DataTemplate>
还有这个
private Point GetCellLocation(DataGrid datagrid, StackPanel stackpanel)
{
DataGridCell cell = (DataGridCell)((ContentPresenter)stackpanel.TemplatedParent).Parent;
int column = cell.Column.DisplayIndex;
int row = ((DataGrid)datagrid).Items.IndexOf(stackpanel.DataContext);
return new Point(column, row);
}
希望能有所帮助谢谢Sheridan,VisualTreeHelper在UIElements方面是一个大帮手。以后我需要记住去上这门课。
<DataGrid x:Name="dataGridView">
<DataGrid.Resources>
<Style TargetType="DataGridRow">
<EventSetter Event="MouseEnter" Handler="Row_MouseEnter"/>
</Style>
</DataGrid.Resources>
</DataGrid>

{
int index = dataGridView.ItemContainerGenerator.IndexFromContainer((DataGridRow)sender);
}
<DataTemplate x:Key="templateCenter">
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" Margin="10 0 10 0">
<Image Source="{StaticResource Back}" Width="15" Height="15"/>

<Image Source="{StaticResource Forward}" Width="15" Height="15"/>
</StackPanel>
</DataTemplate>
private void DragDrop_PreviewDragOver(object sender, DragEventArgs e)
{
if (e.OriginalSource.GetType() != typeof(Image))
{
return;
}
Point destination = GetCellLocation((DataGrid)sender, (StackPanel)((Image)e.OriginalSource).Parent);
}
private Point GetCellLocation(DataGrid datagrid, StackPanel stackpanel)
{
DataGridCell cell = (DataGridCell)((ContentPresenter)stackpanel.TemplatedParent).Parent;
int column = cell.Column.DisplayIndex;
int row = ((DataGrid)datagrid).Items.IndexOf(stackpanel.DataContext);
return new Point(column, row);
}
