public virtual bool PerformAction( UltraGridAction actionCode, bool shift, bool control )
Invoke this method to simulate an action the user can perform.
Many actions are only appropriate in certain situations; if an action is inappropriate, it will not be performed. For example, attempting to delete rows by performing the DeleteRows action (37 - KeyActionDeleteRows) will have no effect if no rows are selected. Similarly, an attempt to toggle a cell's dropdown list by performing a droptown toggle action (14 - KeyActionToggleDropdown) will also be ignored if the column does not have a dropdown list associated with it.
You can use the CurrentState property to determine the state of the control when the action is about to be performed.
