DoubleClick a listview Item

[nsteiner]

Hi all
I have a listview with checkboxes and I would like to catch the doubleclick event on an Item.
Everything is o.k, BUT, the double clicking on the item, also checks/unchecks the checkbox of the item, which I don't want.

Can I work around this ?

Thanks In advance.

You can create a derived class and override WndProc to bypass the WM_LBUTTONDBLCLK message:

public class MyListView : ListView
{
    const int WM_LBUTTONDBLCLK = 0x203;
    protected override void WndProc(ref Message m)
    {
        if (m.Msg == WM_LBUTTONDBLCLK)
        {
            // raise the event
            this.OnDoubleClick(EventArgs.Empty);
 
            // but don't pass the message to base class
            return;
        }
 
        base.WndProc(ref m);
    }
}

Then open your Form.Designer.cs file and replace System.Windows.Forms.ListView with MyListView.

There are also some custom open-source controls like ObjectListView, some of which are a bit friendlier to use than ListView, and you have the source to customize it further to your needs.
