HeaderClick is an overridden method in TCustomDBGrid. It reimplements the method introduced in TCustomGrid to call the private DoHeaderClick method when a column header is clicked (IsColumn is True). This causes the OnTitleClick event handler to be signalled (when assigned) if a column has been defined for the column number in Index.
HeaderClick does not call the inherited method.
HeaderClick is called from the inherited MouseUp and DialogChar methods.
