UnCheckedValue

Value to be returned when no Radio Buttons are checked in the same RadioButtonGroup.

Value to be returned when a CheckBox is not in checked state.

When no RadioButtons are in checked state in the same RadioButtonGroup, GetInputValue/GetInputNumberValue/GetInputXML/GetInputJSON functions return a blank value. If you want to get a text value, set UnCheckedValue to the text you want to get.

When a CheckBox is not in checked state, GetInputValue/GetInputNumberValue/GetInputXML/GetInputJSON functions return a text of the CheckBox in the format of "text::false". The text "::false" is the default text. If you want to get some other text value, set UnCheckedValueto value other than "::false".
