The server-side Reordered event occurs when the tabs of the RadTabStrip are reordered.
This event will be fired only when the EnableDragToReorder property is set to "true"
The Reordered event handler receives two arguments:
The RadTabStrip firing the event. This argument is of type object, but can be cast to the RadTabStrip type.
A RadTabStripReorderedEventArgs object with the following two properties: Tab and Offset. The Tab property is a reference to the tab which has been reordered, the Offset property is the difference between zero-based index of the tab before it has been reordered and after the reorder operation.
