Remarks

The InvalidateCardField method may be useful when you custom paint card fields and need to redraw a particular field due to custom changes that don’t lead to automatic repainting. Refer to the Manually Invalidating Controls topic for more information.

Note

Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the InvalidateCardField member must not be invoked for these Views. The InvalidateCardField 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.

• GridControl.MainView - returns the top most View in a grid;
• GridControl.FocusedView - returns the focused View;
• GridControl.DefaultView - returns the currently maximized View;
• the sender parameter of View specific events;
• GridView.GetDetailView - returns a detail clone View for a specific master row.
