This property gets or sets the required status for a control value in a form.
Syntax
VARIANT_BOOL IsRequiredControl { get; set; }
Value
VARIANT_TRUE if the control's value is required, VARIANT_FALSE otherwise.
Remarks
If set to VARIANT_TRUE, the control must have a value at the time it is exported by a submit-form action (see CreateSubmitFormAction). If the control doesn't contain a value, then the submit action is not executed.
