How To Find Name Property Of Parent Element When ContextMenu MenuItem Is Clicked

I have the following code which creates a new Button with a ContextMenu with a single MenuItem called "Remove".

My question is...in the removeItem_Click EventHandler, how do I find out the Name property of the Button that contained this ContextMenu MenuItem?

private Button CreateRdpConnectionButton(string content, string name)
{
    var newButton = new Button();            
    newButton.Content = content;
    newButton.Name = name;
    newButton.HorizontalContentAlignment = System.Windows.HorizontalAlignment.Left;

    ContextMenu menu = new ContextMenu();
    MenuItem item = new MenuItem();
    item.Header = "Remove";
    item.Click += removeItem_Click;
    menu.Items.Add(item);

    newButton.ContextMenu = menu;
}

void removeItem_Click(object sender, RoutedEventArgs e)
{
    // TODO: Find name of Button that contained this item
}

Store data as <Button Tag=""/> and retrieve the tag as (sender as Button).Tag

You could also directly access the parents:

void removeItem_Click(object sender, RoutedEventArgs e)
{
    // Find name of Button that contained this item
    MenuItem    menuItem      = (MenuItem)sender;
    ContextMenu contextMenu   = (ContextMenu)menuItem.Parent;
    Button      button        = (Button)contextMenu.PlacementTarget;

    string buttonName = button.Name;
}

Use (MenuItem)sender to access your menu item

You could store that info in the item.Tag when you create it, then in the handler you can just cast the sender (to MenuItem) and retrieve it again.
