RegularExpressionValidator Class
Provides control capability to validate that another control's value matches a provided regular expression.
Assembly: System.Web.Mobile (in System.Web.Mobile.dll)
[AspNetHostingPermissionAttribute(SecurityAction::InheritanceDemand, Level = AspNetHostingPermissionLevel::Minimal)] [AspNetHostingPermissionAttribute(SecurityAction::LinkDemand, Level = AspNetHostingPermissionLevel::Minimal)] public ref class RegularExpressionValidator : public BaseValidator
<mobile:RegularExpressionValidator />
This class behaves identically to the ASP.NET System.Web.UI.WebControls::RegularExpressionValidator control.
By default, Command controls on a form raise validator controls on the form to perform validation when the form is submitted to the server. To disable automatic validation, set the CausesValidation property on the Command to false.
The following example shows how you can add regular expression properties, such as the ValidationExpression and Text properties, programmatically during a page load.

This example has a text box that accepts user input, which is a potential security threat. By default, ASP.NET Web pages validate that user input does not include script or HTML elements. For more information, see Script Exploits Overview. |
