你可以，但它是不漂亮！ 
<GroupBox>
<GroupBox.Header>
<TextBlock Text="Hello">
<TextBlock.RenderTransform>
<RotateTransform Angle="90" CenterX="0" CenterY="0" />
</TextBlock.RenderTransform>
</TextBlock>
</GroupBox.Header>
<TextBlock Text="World!"/>
</GroupBox>
你也將需要修改style of the GroupBox支持這一點。
這看起來像它只是一個有幾行，兩個內容主持人和幾個邊界的網格，所以應該可以將其轉換爲列並從那裏出發。我實際上是將Rotate放在ContentPresenter的頭部，這樣你就可以將你的風格應用到任何你想要的地方。
最後更新
通過提取模板出來的標準控制，我們可以修改它以輪動頭的，但是我們也發現，有用來掩蓋周圍邊框的轉換器。通過使用反編譯器（DotPeek），我們還可以切換行和列來將間隙移動到一側。
所以模板看起來像這樣

而且修改後的轉換器看起來像這樣

感謝您的代碼，是的，我會努力減少白色空間，否則它看起來不正確。 – wonea
只需刪除中的所有內容即可完全刪除白色間隙。 –

謝謝我需要弄清楚如何繪製文本上方的文本，即改變繪圖順序。 – wonea
