ColumnView.ClearColumnErrors() Method

Removes error descriptions for the focused row.

Namespace: DevExpress.XtraGrid.Views.Base

Assembly: DevExpress.XtraGrid.v19.2.dll

Declaration

C#

public virtual void ClearColumnErrors()

VB.NET

Public Overridable Sub ClearColumnErrors

Remarks

Use the ClearColumnErrors method to clear the errors set using the ColumnView.SetColumnError method. For instance, if the end-user entered invalid data, then you could set column errors via ColumnView.SetColumnError and indicate cells with invalid values. After the errors are corrected, you can call the ClearColumnErrors method to remove error icons.

As a rule you need to handle the BaseView.ValidatingEditor or the ColumnView.ValidateRow event in order to check cells contents validity.

Note: the ClearColumnErrors method does not clear errors notified by the data source. To clear these errors, you need to use members provided by your data source.

Note

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