This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

Determines whether the content in the input control is valid.

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

protected:
virtual bool EvaluateIsValid() override

Return Value

Type: System::Boolean
true if the control is valid; otherwise, false.

The following code example demonstrates how to override the EvaluateIsValid method in a custom server control so that it always validates that the value exists and is within the maximum and minimum values specified for the RangeValidator.

No code example is currently available or this language may not be supported.
