ImageViewerControl allowDrop problem

I’m using the ImageViewerControl like that below.

and

the video:videoControl is the ImageViewerControl

ImageViewerControl view = ...;
view.AllowDrop = true;

​But, does not drop event invoked.

​So, try like that

ImageViewerControl view = ...;
view.AllowDrop = true;
view.DragDrop += View_DragDrop;
 
private void View_DragDrop(object sender, System.Windows.Forms.DragEventArgs e)
{
....
}

​then, the View_DrapDrop function invoked alone.

​But..

​I want to process the drpp event on videoView.

​How to? Is it possible?

​The milestone can throw the event to the parent?

I dont think we can make the ImageViewerControl as a drag-n-drop. In the Smart Client we support dragging the camera name to a ViewItem, and internally we can drag the header of the CamerViewItem - to swap two ViewItems.

We do not have any samples showing this kind of operation in a standalone application.
