DisableDragDrop
property for PowerScript controls
Applies to
TreeView controls
Description
The DisableDragDrop property determines whether events for dragging,
such as BeginDrag, are triggered when the user clicks on an item within
the control and drags. DisableDragDrop affects only the dragging of items
within the control.
When DisableDragDrop is true, no drag events occur when the user
tries to drag an item. To implement drag and drop, write scripts for the
appropriate dragging events.
DisableDragDrop also affects when selection occurs. When it is true,
an item the user clicks is selected when the mouse button is pressed down.
When it is false, the item is selected when the mouse button is
released.
Usage

-
Select the DisableDragDrop check box on the General page of the
control’s Properties view.
