CompareValidator.ControlPropertiesValid Method

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

Checks the properties of the control for valid values.

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

protected:
virtual bool ControlPropertiesValid () override
protected boolean ControlPropertiesValid ()
protected override function ControlPropertiesValid () : boolean

Return Value

true if the control properties are valid; otherwise, false.

The following code example demonstrates how to override the ControlPropertiesValid method in a custom server control so that it always returns the value of the visible property, as long as the ControlToCompare property of the CompareValidator control is on the page and contains validation properties.

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