Description

HeaderSizing is an overridden method used to perform actions when a column or a row is being resized using the mouse. HeaderSizing calls the inherited method on entry, and signals the OnHeaderSizing event handler when assigned.

HeaderSizing is called from the DoColSizing and DoRowSizing methods when GridState has the value gsColSizing or gsRowSizing.
