Answer 1

I think an alternative solution, is using Telerik components.

A RadListControl can give you that option:

Answer 2

I know it has been a while, but I found this in my search for a list box and thought I would add it to the discussion.

If you have a listbox and want to disable all of the checkboxes so they cannot be clicked, but not disable the control so the user can still scroll etc. you can do this:

listbox.SelectionMode = SelectionMode.None

Answer 3

Combining 2 of the above partial answers worked great for me. Add your items to the list with:

myCheckedListBox.Items.Add(myItem, myState);

Where myState is CheckState.Indeterminate for items that should be disabled. Then add an event handler to keep those items from being changed:

myCheckedListBox.ItemCheck += (s, e) => { if (e.CurrentValue == CheckState.Indeterminate) e.NewValue = CheckState.Indeterminate; };

This does not allow you to use 'Indeterminate' in this list for its normal purpose but it does give a look very similar to what one would expect for a disabled item and it provides the correct behavior!

Answer 4

To disable any particular item use following:

checkedListBox1.SetItemCheckState(0, CheckState.Indeterminate);

SetItemCheckState takes index of item and CheckState Enum Indeterminate is used to show shaded appearance

Answer 5

This works for me:

checkedListBox1.SelectionMode = SelectionMode.None;

Which means no items can be selected

None: No items can be selected.
