Subscribing to the Events of an Element

In This Topic

The following example demonstrates how to subscribe the MouseEnter and MouseLeave events of each DataRow using EventTriggers in an implicit style. The MouseEnter and MouseLeave event handlers are provided below.

XAML	Copy Code
<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid"> <Grid.Resources> <xcdg:DataGridCollectionViewSource x:Key="cvs_orders" Source="{Binding Source={x:Static Application.Current}, Path=Orders}"/> <Style TargetType="{x:Type xcdg:DataRow}"> <EventSetter Event="MouseEnter" Handler="DataRowMouseEnter"/> <EventSetter Event="MouseLeave" Handler="DataRowMouseLeave"/> </Style> </Grid.Resources> <xcdg:DataGridControl x:Name="OrdersGrid" ItemsSource="{Binding Source={StaticResource cvs_orders}}" View="TableView.LunaNormalColorTheme"/> </Grid>

XAML

Copy Code

<Grid xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid">
  <Grid.Resources>
    <xcdg:DataGridCollectionViewSource x:Key="cvs_orders"
                                       Source="{Binding Source={x:Static Application.Current},
                                                        Path=Orders}"/>
    <Style TargetType="{x:Type xcdg:DataRow}">
      <EventSetter Event="MouseEnter"
                   Handler="DataRowMouseEnter"/>
      <EventSetter Event="MouseLeave"
                   Handler="DataRowMouseLeave"/>
    </Style>
  </Grid.Resources>
    
  <xcdg:DataGridControl x:Name="OrdersGrid"
                        ItemsSource="{Binding Source={StaticResource cvs_orders}}"
                        View="TableView.LunaNormalColorTheme"/>
</Grid>

The following code provides the implementation of the MouseEnter and MouseLeave event handlers, which change the background color of a DataRow when the mouse enters and resets it when the mouse leaves.

VB.NET	Copy Code
Private Sub DataRowMouseEnter(ByVal sender As Object, ByVal e As MouseEventArgs) Dim row As Xceed.Wpf.DataGrid.DataRow = TryCast(sender, Xceed.Wpf.DataGrid.DataRow) If Not row Is Nothing Then row.Background = Brushes.Pink End If End Sub Private Sub DataRowMouseLeave(ByVal sender As Object, ByVal e As MouseEventArgs) Dim row As Xceed.Wpf.DataGrid.DataRow = TryCast(sender, Xceed.Wpf.DataGrid.DataRow) If Not row Is Nothing Then row.Background = DataGridControl.GetParentDataGridControl( row ).Background End If End Sub

VB.NET

Copy Code

Private Sub DataRowMouseEnter(ByVal sender As Object, ByVal e As MouseEventArgs)
  Dim row As Xceed.Wpf.DataGrid.DataRow = TryCast(sender, Xceed.Wpf.DataGrid.DataRow)
  If Not row Is Nothing Then
    row.Background = Brushes.Pink
  End If
End Sub
Private Sub DataRowMouseLeave(ByVal sender As Object, ByVal e As MouseEventArgs)
  Dim row As Xceed.Wpf.DataGrid.DataRow = TryCast(sender, Xceed.Wpf.DataGrid.DataRow)
  If Not row Is Nothing Then
    row.Background = DataGridControl.GetParentDataGridControl( row ).Background
  End If
End Sub

C#	Copy Code
private void DataRowMouseEnter( object sender, MouseEventArgs e ) { Xceed.Wpf.DataGrid.DataRow row = sender as Xceed.Wpf.DataGrid.DataRow; if( row != null ) { row.Background = Brushes.Pink; } } private void DataRowMouseLeave( object sender, MouseEventArgs e ) { Xceed.Wpf.DataGrid.DataRow row = sender as Xceed.Wpf.DataGrid.DataRow; if( row != null ) { row.Background = DataGridControl.GetParentDataGridControl( row ).Background; } }

Copy Code

private void DataRowMouseEnter( object sender, MouseEventArgs e )
{
  Xceed.Wpf.DataGrid.DataRow row = sender as Xceed.Wpf.DataGrid.DataRow;
  if( row != null )
  {
    row.Background = Brushes.Pink;
  }
}
private void DataRowMouseLeave( object sender, MouseEventArgs e )
{
  Xceed.Wpf.DataGrid.DataRow row = sender as Xceed.Wpf.DataGrid.DataRow;
  if( row != null )
  {
    row.Background = DataGridControl.GetParentDataGridControl( row ).Background;
  }
}
