ColumnView.IsValidRowHandle(Int32) Method
Indicates whether the specified row handle is valid.
Namespace: DevExpress.XtraGrid.Views.Base
Assembly: DevExpress.XtraGrid.v19.1.dll
Declaration
Parameters
| Name | Type | Description |
|---|---|---|
| rowHandle | Int32 | An integer value specifying the row’s handle. |
Returns
| Type | Description |
|---|---|
| Boolean | true if the row’s handle is valid; otherwise, false. |
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 real Views that are displayed within the Grid Control. The real Views with which an end-user interacts at runtime can be accessed using the following methods.
- 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.
