TreeView ignore double click only at checkbox

Question

I have a treeview with checkbox, I\'m trying to disable the double click only when this is done in the checkbox.

I found a way to totally disable the double click bu

Answer 1

Option 1: Completely disable the double click event.
Create a customer control

class MyTreeView : TreeView
{
    protected override void WndProc(ref Message m)
    {
        if (m.Msg == 0x0203)
        {
            m.Result = IntPtr.Zero;
        }
        else
        {
            base.WndProc(ref m);
        }
    }
}

and in your designer file ( form.Designer.cs ), look for where the control was created, and replace the call to TreeView constructor with your new control.

this.treeView1 = new MyTreeView();

Option 2: Treat a double click event as two single click events

class MyTreeView : TreeView
{
    protected override void WndProc(ref Message m)
    {
        if (m.Msg == 0x0203)
        {
            m.Msg = 0x0201;
        }
        base.WndProc(ref m);
    }
}

Personally I think option 2 is more intuitive. When user clicks the check box twice, the checkbox is not checked.
