BaseValidator Class

Provides the core implementation for all validation controls derived from this class. As an abstract class, it cannot be instantiated.

Namespace:  System.Web.UI.MobileControls
Assembly:  System.Web.Mobile (in System.Web.Mobile.dll)

[AspNetHostingPermissionAttribute(SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermissionAttribute(SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal)]
public abstract class BaseValidator : TextControl, 
<mobile:BaseValidator />

The BaseValidator class inherits from the TextControl base class, and thus has a Text property. In the event of an invalid entry, the validator displays the value of the Text property. If the property is not set, the validator displays the value of the ErrorMessage property instead; this is the text that is shown in the ValidationSummary control. This behavior is consistent with Web Forms validators.

Of the ASP.NET mobile controls, those that support validation are the TextBox control (its Text property) and the SelectionList control (its SelectedIndex property). Other controls can participate in validation by including a ValidationPropertyAttribute attribute. For more information, see the How to: Validate Against a Specific Value for ASP.NET Server Controls documentation.

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
