Add the Filter Row filter mode functionality to VirtualGrid similar to the GridView.

The Multiple and Extended selection modes allow you to select and deselect multiple items. The deselection of items doesn't work.

Add an event (for example named QueryCursor) to the RadVirtualGrid control, that is invoked each time the control tries to replace the Mouse.OverrideCursor static property's value. The event should give information about the new cursor (also possibly for the old one) and it should allow the developer to replace the cursor with its own instance.
