private void工具栏\u已加载（对象发送方，路由目标）
{
工具栏=发送者作为工具栏；
var overflowGrid=toolBar.Template.FindName（“overflowGrid”，toolBar）作为框架元素；
if（overflowGrid！=null）
{
overflowGrid.Visibility=可见性。折叠；
}
var mainPanelBorder=toolBar.Template.FindName（“mainPanelBorder”，toolBar）作为框架元素；
如果（mainPanelBorder！=null）
{
主面板边框。边距=新厚度（0）；
}
}
Edit2:修复了丢失的资源。
或者，您可以使用样式的副本，更改前面提到的可见性并删除右侧的边距，所有这些资源都属于样式/模板：

为工具栏大小更改事件指定以下方法
private void ToolBar_SizeChanged(object sender, SizeChangedEventArgs e)
{
ToolBar toolBar = sender as ToolBar;
var overflowGrid = toolBar.Template.FindName("OverflowGrid", toolBar) as FrameworkElement;
if (overflowGrid != null)
{
overflowGrid.Visibility = toolBar.HasOverflowItems ? Visibility.Visible : Visibility.Collapsed;
}
var mainPanelBorder = toolBar.Template.FindName("MainPanelBorder", toolBar) as FrameworkElement;
if (mainPanelBorder != null)
{
var defaultMargin = new Thickness(0, 0, 11, 0);
mainPanelBorder.Margin = toolBar.HasOverflowItems ?defaultMargin: new Thickness(0);
}
}
我有四个小时的时间用MVVM正确地完成这项工作（因此没有代码落后） 最重要的是切换按钮和
