CheckedListBox.setItemChecked

Question

Does anyone know how I can get the checked items to actually display themselves if I update checked state for any of them within Form1_Load with code like: this.CheckedListBox.SetItemChecked(0 true); I've examined the values of the items (after setting code like above) and the expected values are confirmed BUT I still see no checks. E.g.: MessageBox.Show(CheckedCount:  + this.CheckedListBox.CheckedItems.Count.ToString() +  item 0:  + this.CheckedListBox.GetItemChecked(0).ToString() +  item 1:  + this.CheckedListBox.GetItemChecked(1).ToString()); This results in something like: 2 item0: true item1: false. BUT still no visible checks are seen!!!! (I'm aware that the CheckedListBox control has some issues with it forgetting checks but this is slightly different since I'm not doing things like switching tab pages which I believe can cause such problems.) Anyone know what the problem is???

Have you tried calling CheckedListBox.Invalidate?

I have the exact same problem. I've tried everything I know to get the check box to show. Hopefully some expert will answer this question for us. Otherwise I'm thinking these checkedlistboxes aren't all they are checked up to be...
