    When I try to add the handlers



    RadDragAndDropManager.AddDragQueryHandler(this, OnDragQuery); RadDragAndDropManager.AddDropQueryHandler(this, OnDropQuery); RadDragAndDropManager.AddDropInfoHandler(this, OnDropInfo);




    I continue to get the error 
    The name 'OnDragQuery' does not exist in the current context 
    The name 'OnDropQuery' does not exist in the current context
    The name 'OnDropInfo' does not exist in the current context

    Any idea what I am doing wrong?

    Hello Brian Baker,

    After you subscribe to the DragDrop events like you do, you need to create the event handlers, like so:

    // OnDragQuery event handler
    private void OnDragQuery( object sender, DragDropQueryEventArgs e )
    // OnDropQuery event handler
    private void OnDropQuery( object sender, DragDropQueryEventArgs e )
    // OnDropInfo event handler
    private void OnDropInfo( object sender, DragDropEventArgs e )
    // OnDragInfo event handler
    private void OnDragInfo( object sender, DragDropEventArgs e )

    You can also take a look at this HowTo article. Please give it a try and let us know if it works for you or if you need more info.
