Name Type Description
column GridColumn

A GridColumn object representing the column whose header is to be repainted. null (Nothing in Visual Basic) to invalidate the entire column header panel.


The InvalidateColumnHeader method may be useful when you custom paint column headers and need to redraw a particular header or all headers at once due to custom changes that don’t lead to automatic repainting. Refer to the Manually Invalidating Controls topic for more information.


Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the InvalidateColumnHeader member must not be invoked for these Views. The InvalidateColumnHeader member can only be used with Views that display real data within the Grid Control. Use the following methods to access these Views with which an end user interacts at runtime.
