RegularExpressionValidationPattern.ErrorText Property

Gets or sets the error text to be displayed within the editor’s error frame if the editor’s specific regular expression validation fails.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v21.1.dll

Declaration

[DefaultValue("Regular expression validation failed")]
public override string ErrorText { get; set; }

Property Value

Type Default Description
String

“Regular expression validation failed”

A String value that specifies the error text.

Remarks

The ErrorText property allows you to specify an error text to be displayed if the editor’s specific regular expression (specified via the RegularExpressionValidationPattern.ValidationExpression property) validation fails. If the property value is empty, the ValidationSettings.ErrorText property value is used instead.

You can override an error text within validation events, via the ASPxClientEditValidationEventArgs.errorText parameter of the client-side ASPxClientEdit.Validation event or via the ValidationEventArgs.ErrorText parameter of the server-side ASPxEdit.Validation event.
