GridView.InvalidateRowCell(Int32, GridColumn) Method

Invalidates the specified data cell.

Namespace: DevExpress.XtraGrid.Views.Grid

Assembly: DevExpress.XtraGrid.v19.1.dll

Declaration

C#

public virtual void InvalidateRowCell(
    int rowHandle,
    GridColumn column
)

VB.NET

Public Overridable Sub InvalidateRowCell(
    rowHandle As Integer,
    column As GridColumn
)

Parameters

Name	Type	Description
rowHandle	Int32	An integer value specifying the handle of the row that contains the cell.
column	GridColumn	A GridColumn object representing the column to which the cell belongs.

Remarks

The InvalidateRowCell method may be useful when you custom paint 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 InvalidateRowCell member must not be invoked for these Views. The InvalidateRowCell 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.
