Remarks

You can use CompleteRecordDragDrop event to implement a copy operation that does not remove records when dragging.

For example, if you have implemented Drag-and-Drop Between GridControls, you can handle the CompleteRecordDragDrop event to deny removing records:

<dxg:GridControl Name="gridControl1">
   <!---->
   <dxg:GridControl.View>
      <dxg:TableView AllowDragDrop="True" CompleteRecordDragDrop="OnCompleteRecordDragDrop" />
   </dxg:GridControl.View>
</dxg:GridControl>
void OnCompleteRecordDragDrop(object sender, CompleteRecordDragDropEventArgs e) {
   e.Handled = true;
}

The CompleteRecordDragDrop event is raised before the GridControl updates its ItemsSource collection. Use the Dispatcher.BeginInvoke method to invoke certain logic after the ItemsSource collection is modified.
