ExceptionCondition

No value is specified for the ControlToValidate property.

- or -

The input control specified by the ControlToValidate property is not found on the page.

- or -

The input control specified by the ControlToValidate property does not have a ValidationPropertyAttribute attribute associated with it; therefore, it cannot be validated with a validation control.

The ControlPropertiesValid method is a helper method used primarily by the PropertiesValid property to determine whether the ControlToValidate property contains a valid input control. To be a valid input control, the ControlToValidate property must be set to some value and that value must be a control on the page that supports validation.

NoteNote:

This method is used primarily by control developers.
