GridView.InvalidateRowIndicator(Int32) Method

Invalidates the indicator panel cell corresponding to the specified row.

Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v23.2.dll

NuGet Packages: DevExpress.Win.Grid, DevExpress.Win.Navigation

Declaration

C#

public virtual void InvalidateRowIndicator(
    int rowHandle
)

VB.NET

Public Overridable Sub InvalidateRowIndicator(
    rowHandle As Integer
)

Parameters

Name	Type	Description
rowHandle	Int32	An integer value representing the handle of the row whose corresponding indicator cell is to be repainted.

Remarks

The InvalidateRowIndicator method may be useful when you custom paint indicator cells and need to redraw a particular cell 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 InvalidateRowIndicator member must not be invoked for these Views. The InvalidateRowIndicator 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.
