Declaration

Description
ColRowExchanged is overridden in
TCustomDrawGrid and
implements the method defined in the ancestor class. It is used to perform
actions needed when column or row values are exchanged (swapped) in the grid
control.
IsColumn indicates whether columns or rows are affected in the method. When set to True, column values at the specified positions are exchanged. When set to False, row values are exchanged.
If the Columns property has not been enabled, ColRowExchanged calls the ExchangeColRow method in the internal TVirtualGrid instance for the control.
ColRowExchanged signals the OnColRowExchanged event handler (when assigned).
ColRowExchanged is called from the DoOPExchangeColRow method in the ancestor class.
