Remarks
Use the CalcHitInfo method to determine which element is located at a specific point. For instance, this can be used when handling the View’s Click event to determine which element was clicked. In such instances, you will pass the current mouse pointer’s coordinates as the method’s parameter.
When called for card, grid and Banded Grid Views this method returns the CardHitInfo, GridHitInfo and BandedGridHitInfo objects respectively. Refer to these topics for details on what information is provided by the method’s return value.
The Hit Information topic provides general information on obtaining and using hit information.
Note
Detail pattern Views do not contain data and they are never displayed within XtraGrid. So, the CalcHitInfo member must not be invoked for these Views. The CalcHitInfo 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.
