Question

When an item is clicked in the checkedlistbox, it gets highlighted. How can I prevent this highlighting effect?

I can hook into the SelectedIndexChanged event and clear the selection, but the highlighting still happens and you see a blip. In fact, if you hold down the mouse click, never releasing it after you clicked on the checkbox area, the selection remains highlighted until you release the mouse button. I basically want to get rid of this highlighting effect altogether.

this will do it apart from you still get the dotted line bit.

this.checkedListBox1.SelectionMode = System.Windows.Forms.SelectionMode.None; 

although now you can’t click the check boxes… so you’ll have to do something like so:

  private void checkedListBox1_Click(object sender, EventArgs e)     {         for (int i = 0; i < checkedListBox1.Items.Count; i++)         {             if (checkedListBox1.GetItemRectangle(i).Contains(checkedListBox1.PointToClient(MousePosition)))           {               switch (checkedListBox1.GetItemCheckState(i))               {                   case CheckState.Checked:                       checkedListBox1.SetItemCheckState(i, CheckState.Unchecked);                       break;                   case CheckState.Indeterminate:                   case CheckState.Unchecked:                       checkedListBox1.SetItemCheckState(i, CheckState.Checked);                        break;               }             }          }     } 

if all that isn’t what your after.. you can always just make your own one. its a fairly simple control.
