ExceptionEventArgs.ErrorText Property

Gets or sets the error description to be displayed in the message box/tooltip.

Namespace: DevExpress.XtraEditors.Controls

Assembly: DevExpress.XtraEditors.v24.2.dll

Declaration

C#

public string ErrorText { get; set; }

VB.NET

Public Property ErrorText As String

Property Value

Type	Description
String	A string value specifying the text to display in the message box/tooltip.

Remarks

If the ExceptionEventArgs.ExceptionMode property is set to ExceptionMode.DisplayError, the message box displaying the text specified by the ErrorText property is invoked. The message box’s caption is specified by the ExceptionEventArgs.WindowCaption property.

When handling container control events that occur when assigning invalid values to cells, setting the ExceptionEventArgs.ExceptionMode property to ExceptionMode.DisplayError displays a tooltip with the ErrorText string.
