对于初学者，当想到要改变一个控件的模板时都是这样一套写下来的
<TextBox Text="ABC" Width="100" Height="30" Margin="150,15">
<TextBox.Template>
<ControlTemplate>
<Border BorderBrush="Red" BorderThickness="1">
<ScrollViewer x:Name="ContentElement" Padding="{TemplateBinding Padding}" BorderThickness="0" IsTabStop="False"/>
</Border>
</ControlTemplate>
</TextBox.Template>
</TextBox>
但你会发现，这样写，那么功能都不在了，比如我在<ControlTemplate>加入一个border，运行时发现根本就没法输入。当遇到这样的情况时，应该用Blend打开，对象->编辑模板，此时你会发现，它原来的模板出现了，这就是一个完整的模板了，会发现里面用了很多x:name，这时你会发现TextBox有这么一行代码
<ScrollViewer x:Name="ContentElement" Padding="{TemplateBinding Padding}" BorderThickness="0" IsTabStop="False"/>
就是这个x:name决定了是否能够输入，所以，在自己写的模板里就要把这个name加入才有最基本的功能。当我要写一个控件的模板时，我喜欢用blend打开，看原来有哪些属性，希望初学WPF的朋友们多用Blend看看控件的元模板。
以下是完整的代码，运行效果如下：
