Hi Experts,

I've a list box with some value. Now i want another value called "All". So that when i select that all the values should get selected.

When i uncheck that all the values should get unselected.

Hi Manish,

But i want that inside the listbox itself. And again if u uncheck all values should get unselected.

Hi

If all values are unselected, then no filter is applied and this is (nearly*) the same as selecting all values. So I don't think this is going to work the way you seem to be expecting.

*nearly the same because if all values are  selected, all values are possible, except nulls which are excluded; while if nothing is selected, all values are possible, including nulls.
