BaseValidator::ErrorMessage Property

Gets or sets the text for the error message displayed in a ValidationSummary control when validation fails.

Namespace:  System.Web.UI.WebControls
Assembly:  System.Web (in System.Web.dll)

public:
virtual property String^ ErrorMessage {
	String^ get () sealed;
	void set (String^ value) sealed;
}
<asp:BaseValidator ErrorMessage="String" />

Property Value

Type: System::String
The error message displayed in a ValidationSummary control when validation fails. The default value is an empty string (""), which indicates that this property is not set.

Implements

IValidator::ErrorMessage

When using a ValidationSummary control, use the ErrorMessage property to specify the text to display in the ValidationSummary control when validation fails for the current validation control. To specify the text to display in the validation control itself, use the Text property.

NoteNote

If you set the ErrorMessage property without setting the Text property, the value of the ErrorMessage property is also displayed in the validation control.

The value of this property, when set, can be saved automatically to a resource file by using a designer tool. For more information, see LocalizableAttribute and ASP.NET Globalization and Localization.
