Listview ItemSelectionChanged fires twice?

Question

I have a Winforms App in C# with a ListView control. This ListView shows a list of TO-DO items and I am using the \'ItemSelectionChanged\' event to handle updates.

Yes, it will fire twice. Once because the previously selected item became unselected, again for the newly selected item. You just have to make sure you see the selection event:

    private void listView1_ItemSelectionChanged(object sender, ListViewItemSelectionChangedEventArgs e) {
        if (e.IsSelected) {
            // Update form
            //...
        }
    }
