  • Can a CheckBoxItem handle NULL values?

    Hi,

    is it possible to let a CheckBoxItem handle NULL values? I would expect a triple state checkbox, which does not toggle between checked and unchecked, but cycle from checked/unchecked/null.

    The NULL state would be indicated with a gray background.

    Is that possible?

    TIA!

    While I searched the SmartGWT forums for something like that already, I extended my search a bit and found something that HTML5 checkboxes would support something "indeterminate".

    Is something like this available in SmartGwt?

      Hi,

      see the CheckboxItem-docs for emptyValue.

      Best regards
