CompareValidator::EvaluateIsValid Method
When overridden in a derived class, this method contains the code to determine whether the value in the input control is valid.
Assembly: System.Web (in System.Web.dll)
The following code example demonstrates how to override the EvaluateIsValid method in a custom server control so that it always returns true if the values of the two specified controls are the same and false otherwise.
