WPF GroupBox Header Text Issue
提问by BrianKE
I have the following XAML which displays correctly:
我有以下正确显示的 XAML：
<GroupBox Name="RulesGroupBox" Header="Rules">
<StackPanel Name="RulesStackPanel"
HorizontalAlignment="Left">
....
</StackPanel>
</GroupBox>
I now want to make the header text bold using the following (which I know works in other projects):
我现在想使用以下内容（我知道在其他项目中有效）使标题文本变为粗体：
<GroupBox Name="RulesGroupBox">
<GroupBox.Header>
<TextBlock FontWeight="Bold" Text="Rules"></TextBlock>
</GroupBox.Header>
<StackPanel Name="RulesStackPanel"
HorizontalAlignment="Left">
....
</StackPanel>
</GroupBox>
For some reason, in this project, this change has the effect of making the text displayed for the Header text "System.Windows.Controls.TextBlock" and not "Rules". The text is now bold but not displaying "Rules".
出于某种原因，在此项目中，此更改具有使标题文本“System.Windows.Controls.TextBlock”而非“规则”的文本显示的效果。文本现在是粗体，但不显示“规则”。
Any idea why the chagne would not show "Rules" in bold?
知道为什么 chagne 不会以粗体显示“规则”吗？

You likely have changed GroupBox's HeaderTemplateand this template supports displaying only text.
您可能已更改GroupBox'sHeaderTemplate并且此模板仅支持显示文本。

Headeris defined more than once.
Header被定义不止一次。
<GroupBox Name="RulesGroupBox">
<GroupBox.Header>
<TextBlock FontWeight="Bold" Text="Rules"></TextBlock>
</GroupBox.Header>
<StackPanel Name="RulesStackPanel"
HorizontalAlignment="Left">
....
</StackPanel>
</GroupBox>
"Rules" appears in bold with this correction.
此次更正后，“规则”以粗体显示。
