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

protected virtual bool ControlPropertiesValid()

Return Value

Type: System.Boolean
true if the control specified by ControlToValidate is a valid control; otherwise, false.

ExceptionCondition
HttpException

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.
