) As Boolean

Parameters

Name	Type	Description
rowHandle	Int32	An integer value specifying the row’s handle.

Remarks

The row handle is invalid if it doesn’t correspond to any row (data row, group row, new item or auto filter row) displayed within the View.

Note

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