这些方法找不到。[/quote] 用绑定。如果 DishesFontSize 属性属于listboxitem的DataContext的一个属性，那么就可以使用 绑定方式，使用RelativeSource,指定要查询的祖先元素为ListBoxtItem. 类似： FontSize="{Binding DataContext.DishesFontSize,RelativeSource={RelativeSource ListBoxItem}}"

RelativeSource ListBoxItem -> RelativeSource AncestorType=ListBoxItem

[quote=引用 3 楼 Libby1984 的回复:] 这么多的TextBlock你想要哪一个？干嘛用的呢？ 如果你硬要获得的话，你可以使用命中测试，然后遍历命中测试中的命中结果找到TextBlock HitTestResult result = VisualTreeHelper.HitTest(myCanvas, pt); if (result != null) { // Perform action on hit visual object. } 但是如果你想修改模板样式中的某些内容，最好还是用绑定。

普通的绑定解决不了我的问题，我要的是首先获取到控件，然后再动态给这个控件绑定字段[/quote] 那你试试我上面的代码，看应该能满足你的需求
