WPF样式学习：ToolBar的使用

private void ToolBar_Loaded(object sender, RoutedEventArgs e)
{
    //去掉ToolBar右边默认的扩展图标
    ToolBar toolBar = sender as ToolBar;

    var overflowGrid = toolBar.Template.FindName("OverflowGrid", toolBar) as             FrameworkElement;

    if (overflowGrid != null)
    {
    overflowGrid.Visibility = Visibility.Collapsed;
    }
    var mainPanelBorder = toolBar.Template.FindName("MainPanelBorder", toolBar)     as FrameworkElement;

    if (mainPanelBorder != null)
    {
    mainPanelBorder.Margin = new Thickness(0);
    }
}
