Simple C#/WPF code for a MouseDoubleClick on a ListBox item?

Clyde Eisenbeis

There are numerous comments about MouseDoubleClick for a ListBox and ListView. Most are a bit complicated.

One that looks simple is MouseBinding.Gesture Property (System.Windows.Input). However, it is not clear if this would work for a ListBox, or how to implement it.

Is there an example of simple C#/WPF code for a MouseDoubleClick on a ListBox item? The MouseDoubleClick jumps to the C# code (similar to a Button_Click).

Hi Clyde Eisenbeis,

You can utilize the ListBox's MouseDoubleClick event along with the ItemContainerGenerator.

private void ListBox_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    if (e.ChangedButton == MouseButton.Left)
    {
        ListBoxItem item = (ListBoxItem)GetDependencyObjectFromVisualTree((DependencyObject)e.OriginalSource, typeof(ListBoxItem));
        if (item != null)
        {
            // Handle double-click logic here
        }
    }
}

private DependencyObject GetDependencyObjectFromVisualTree(DependencyObject startObject, Type type)
{
    DependencyObject parent = startObject;
    while (parent != null && parent.GetType() != type)
    {
        parent = VisualTreeHelper.GetParent(parent);
    }
    return parent;
}
