Draggable controls
The DragIcon property specifies the icon to display when the user drags the control. The default icon is a box the size of the control. When the user drags a control, the icon displays when the cursor is over an area in which the user can drop the control (a valid drop area). When the cursor is over an area that is not a valid drop area, the no-drop icon displays.
Display the Other tab page of the control’s Properties view.
Click the down arrow on the DragIcon field and select a stock icon from the list of stock icons, or use the Browse button to select another icon (.ICO) file.
The DragIcon property takes a string containing the name of the icon file you want to display when the user drags the control. You can specify a stock icon or any icon filename.
The following example sets the drag icon for a ListBox to an icon called arrow.ico:
lb_1.DragIcon = 'c:\examples\arrow.ico’
This example sets the drag icon to the stock icon Question:
lb_1.DragIcon = 'Question!'
