c# - WPF 我无法以我的风格访问文本块

Question

我制作了一个单选按钮样式，并将其命名为 RadioButtonStyle，但在我后面的代码中，当我编写单选按钮 Q1A 的名称并尝试 Q1A.RadioContentTxt 时，它不会出现。

看。这是我的风格：`

我使用 Blend 制作它。

如何从后面的代码中设置我的 RadioContentTxt.Text？我尝试做 Q1A.Content 但它不起作用。

TextBlock将模板中的绑定到Content控件的属性：

<TextBlock x:Name="RadioContentTxt" Grid.Column="1"  Foreground="#33454B57" TextWrapping="Wrap" 
           Text="{TemplateBinding Content}"  Background="Transparent"/>

...并设置Content属性：

Q1A.Content = "...";

您不能使用控件的属性直接访问模板中的元素。
