如何访问位于ControlTemplate中的WPF控件? [英] How to access a WPF control located in a ControlTemplate?

问题描述

通常，WPF控件在.xaml文件中声明，而不是在后面的代码(.xaml.cs文件)中声明.但是，有时我需要在后面的代码中使用其中一些控件来进行操作.如果该控件驻留"在xaml文件中，该如何获取它的句柄?

Usually, the WPF controls are declared in the .xaml files and not in the code behind (.xaml.cs files). However, sometimes I need to use some of those controls in code behind in order to manipulate them. How can I get the handle of such a control if it "resides" in the xaml file?

推荐答案

您可以使用ControlTemplate类的FindName()方法.

You can use the FindName() method of the ControlTemplate class.

// Finding the grid that is generated by the ControlTemplate of the Button
Grid gridInTemplate = (Grid)myButton1.Template.FindName("grid", myButton1);
