I implemented a drag & drop between two ListBoxes. I made it so, like on your web page “Drag and Drop Between ListBoxes with User Feedback”. It works fine, but the DragCue doesn’t appear.
// OnDragQuery event handler
private void OnDragQuery(object sender, DragDropQueryEventArgs e)
var listBoxItem = e.Options.Source as ContentControl;
if (e.Options.Status == DragStatus.DragQuery && listBoxItem != null)
var sourceControl = e.Options.Source;
var dragCue = RadDragAndDropManager.GenerateVisualCue(sourceControl);
Could you tell me, where is the problem?
