How can I get rid of the grey dropdown area to the right of the text in the toolbar item below?
Here is the code which produces it:
ToolBar tb = new ToolBar();
tb.Background = new SolidColorBrush(Colors.Transparent);
Button button = new Button();
button.Content = "test";
button.Click += new RoutedEventHandler(button_Click);
tb.Items.Add(button);
value.ToolBars.Add(tb);
