Not all controls can be validated with a validation control. This class creates a collection of control IDs on the Web Forms page that can be associated with a validation control. This collection is commonly used in a designer to display a list of controls on the Web Forms page that can be associated with a validation control.

When creating your own validation control, you can enable the designer to display a list of controls that support validation controls. Simply add an attribute to the string property that represents the control to validate, as follows:
