Using Drag and Drop in a Window

To identify the type of control that was dropped, use the source argument of the DragDrop event.

This script for the DragDrop event in a picture declares two variables, then determines the type of object that was dropped:

CommandButton lcb_button
StaticText lst_info
 
IF source.TypeOf() = CommandButton! THEN
      lcb_button = source
      lcb_button.Text = "You dropped a Button!"
ELSEIF source.TypeOf() = StaticText! THEN
      lst_info = source
      lst_info.Text = "You dropped the text!"
END IF
