CompareValidator Class
Assembly: System.Web.Mobile (in system.web.mobile.dll)
Use compare validators to ensure that the values of two text boxes provide the same values, such as confirming a new password.
This class behaves identically to the ASP.NET CompareValidator control.
By default, Command controls on a form raise any 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 controls to false.
Validation succeeds if the input control is empty. Use a RequiredFieldValidator control to require the user to enter data into the input control.
The following example code uses a CompareValidator control (CompareValidator1) to check whether the two text boxes have the same value and alerts the user if they are different.

| 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 (Visual Studio). |
