The OnClientTabDragStart event is fired when a drag-to-reorder operation is about to start.

This event will be fired only when the EnableDragToReorder property is set to "true"

The event handler function receives two parameters:

  1. The instance of the tabstrip firing the event.

  2. An eventArgs parameter containing the following methods:

  • get_tab returns a reference to the RadTab which is about to be dragged.

  • get_domEvent returns a reference to the DOM event object for the action that caused the drag-to-reorder operation to start.

  • set_cancel lets you stop the operation by passing boolen value as a parameter.
