Question

I have a WPF ListView control with a ContextMenu written in XAML Code. With every right-click on the ListView the ContextMenu is shown even when there are no items in the ListView.

This is a behavior I don’t want. The ContextMenu should only open if there are items in the ListView. I have no problem counting the items but I don’t find the right event to suppress the ContextMenu.

How can I do that?

Answer 1

Handle the ContextMenuOpening event of the ListView to cancel the menu if the list is empty :

    private void listView_ContextMenuOpening(object sender, ContextMenuEventArgs e)
    {
        if (listView.Items.Count == 0)
            e.Handled = true;
    }
