WinForms ListBox with readonly/disabled items

Question

Is there a way to make some of the items in a ListBox readonly/disabled so they can\'t be selected? Or are there any similar controls to ListBox to provide this functionalit

Answer 1

To get read-only behaviour I have MyCBLLocked, a boolean associated with the MyCBL checkbox list control, and on the CheckItem event I do:

private void MyCBL_ItemCheck(object sender, ItemCheckEventArgs e)
{
    if (MyCBLLocked)
        e.NewValue = e.CurrentValue;
    }

So instead of

MyCBL.Enabled = false;

I use

MyCBLLocked = true;

and the user can scroll through the many selections but not mess things up with changes.
