Listbox style setting

Normal checkbox control has a value property and we can set to 2 for dimmed appearance. The listbox control has a style property and we can set to 1 to have a checkbox associated with each item. But this time we can only check and uncheck.

Is there any way we can also make this checkbox (associated with listbox control) to dim. I really need to capture 3 values whether the item is 1) checked 2)not-checked or 3)not applicable (by dim)

Could any one help me.

Thanks in advance

Rather than use the

Check1.Value = 2

property (Dimmed).. try using

Check1.Enabled = False

instead.. <smile>.

I am sorry, I actually wanted to mean grayed rather than dimmed.

I understood what you meant.. the intent of grayed / dimmed is to preclude the user from clicking on a meaningless item. My thought was that the Enabled property MIGHT work instead.

To be honest.. the more I think about this.. i am unclear on what you are trying to do. Could you possibly elaborate as to why you want to have the "greyed" setting?

Actually I can not disable any item is a list box (can I). What I want to do is - user has three choice in a list of check items. They can say completed (ticked), Not completed (clear or unticked) and not applicable (gray)

Unfortunately the listbox's checkbox only supports two states.
You could fake a tri-state checkbox using images (perhaps on a subitem in report mode) and some click-handling, or using an ownerdraw listbox (but this is very complicated).

Not sure why I got the points, I suppose a B was appropriate here.
