Namespace: System.Windows.Forms.Design
Assembly: System.Design (in System.Design.dll)

Protected Overrides Sub OnDragDrop ( _
    de As DragEventArgs _

protected override void OnDragDrop(
    DragEventArgs de
)

Visual C++

protected:
virtual void OnDragDrop(
    DragEventArgs^ de

override OnDragDrop : 
        de:DragEventArgs -> unit

Parameters

de: Type: System.Windows.Forms..::.DragEventArgs
A DragEventArgs that provides data for the event.

Remarks

This method checks any parent control for a drag-and-drop handler that can handle the operation instead. If one exists, this method passes the DragEventArgs to the method and returns. If no parent drag-and-drop handler exists, this method attempts to create a tool if a toolbox item has been dropped on the designer control.
