Greying elements in listbox of checkbox style

[suhaib]

Hi Guys

I am pursuing something which I dont even know is possible - just help me out please.

I have a listbox control whose style is set to Checkbox.
I am populating this listbox with about 10 elements, all set to true (checked)
Out of these 10 elements a couple of them I dont want the user to uncheck them any time - and hence want these few items to appear 'grey' (as disabled).
I did find a way out of doing this programatically that is checking these certain elements everytime they are unchecked - but the requirment here is that they should be 'greyed' instead.

Thanks in advance

If you don't want the user to change them, then why put them there? That may be bad GUI design.

Not agree with you, spuppett.
Matter is:
let them displayed among others
to signal users they exists but tell
users they cannot deal with them;
like for example in a setup software,
where you have to tell users some
components must be installed. You
see them in same list with those you
can choose, but they are grayed

It seems to me the control is not enough
flexible to obtain the goal.

Now, suhaib, you might try with a Treeview, which
allow more customization over each node...
