Namespace: DevExpress.XtraGrid.Views.Base
Assembly: DevExpress.XtraGrid.v24.2.dll

Name | Type | Description |
---|---|---|
r | Rectangle | A System. |
#Remarks
To force immediate repainting of invalidated regions (before other processing takes place), call the Update method of the grid control after invalidation.
View regions are automatically invalidated when required. However, you may need to invalidate View regions manually if you implement some specific functionality. For instance, this may be needed when you custom paint View elements. Refer to the Manually Invalidating Controls help topic for details on when manual invalidation is required and how it can be performed.
