ValidateRowEventArgs.ErrorText Property

Gets or sets the error description.

Namespace: DevExpress.XtraGrid.Views.Base

Assembly: DevExpress.XtraGrid.v18.2.dll

Declaration

C#

public string ErrorText { get; set; }

VB.NET

Public Property ErrorText As String

Property Value

Type	Description
String	A string representing the error description.

Remarks

You can use the ErrorText property to provide text explaining why validation failed. If setting the ValidateRowEventArgs.Valid property to false, the text will be displayed within a message box. Note that the text will be followed by the ‘Do you want to correct the value?‘ string.

If handling the ColumnView.InvalidRowException event, you can modify the error message box’s text before displaying it. Note also, that this event can prevent the display of the message box.
