Handling edit events2

The following example demonstrates how to subscribe to the Cell.EditBeginning and EditBegun routed events as well as how to handle and cancel them.

The following code provides the implementation of the EditBeginning and EditBegun event handlers.

VB.NET	Copy Code
Public Sub EditBeginning( ByVal sender As Object, ByVal e As CancelRoutedEventArgs ) If Me.cancelBeginEdit.IsChecked = True Then e.Cancel = True End If If Me.handledByRowCheckBox.IsChecked = True Then e.Handled = True End If Debug.WriteLine( sender + ": EditBeginning" ) End Sub Public Sub EditBegun( ByVal sender As Object, ByVal e As RoutedEventArgs ) If Me.handledByRowCheckBox.IsChecked = True Then e.Handled = True End If Debug.WriteLine( sender + ": EditBegun" ) End Sub

VB.NET

Copy Code

Public Sub EditBeginning( ByVal sender As Object, ByVal e As CancelRoutedEventArgs )
   If Me.cancelBeginEdit.IsChecked = True Then
      e.Cancel = True
   End If
   If Me.handledByRowCheckBox.IsChecked = True Then
     e.Handled = True
   End If
   Debug.WriteLine( sender + ": EditBeginning" )
End Sub
Public Sub EditBegun( ByVal sender As Object, ByVal e As RoutedEventArgs )
   If Me.handledByRowCheckBox.IsChecked = True Then
     e.Handled = True
   End If
   Debug.WriteLine( sender + ": EditBegun" )
End Sub

C#	Copy Code
public void EditBeginning( object sender, CancelRoutedEventArgs e ) { e.Cancel = ( this.cancelBeginEdit.IsChecked == true ); e.Handled = ( this.handledByRowCheckBox.IsChecked == true ); Debug.WriteLine( sender + ": EditBeginning" ); } public void EditBegun( object sender, RoutedEventArgs e ) { e.Handled = ( this.handledByRowCheckBox.IsChecked ?? true ); Debug.WriteLine( sender + ": EditBegun" ); }

Copy Code

public void EditBeginning( object sender, CancelRoutedEventArgs e )
{
  e.Cancel = ( this.cancelBeginEdit.IsChecked == true );
  e.Handled = ( this.handledByRowCheckBox.IsChecked == true );
  Debug.WriteLine( sender + ": EditBeginning" );
}
public void EditBegun( object sender, RoutedEventArgs e )
{
  e.Handled = ( this.handledByRowCheckBox.IsChecked ?? true );
  Debug.WriteLine( sender + ": EditBegun" );
}
