String	"*"	A String value that specifies the error text.

Remarks

The ErrorText property allows you to specify an error text to be displayed if a required editor’s value (the editor’s RequiredFieldValidationPattern.IsRequired property is set to true) is not specified. 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.
