我有一個WrapPanel包含 aLabel和 a CheckBox; 當MouseLeftButtonUp事件在包裝板上觸發時，復選框被選中。這個想法是讓標簽和復選框看起來像 1 個元素。
現在，該CheckBox元素具有此功能，即當滑鼠懸停在其上時，它會被藍色邊框包圍。在我的情況下，當復選框直接被滑鼠懸停時（而不是整個包裝面板），復選框僅將藍色邊框帶到自身。當滑鼠懸停在包裝面板上時，我需要我的復選框來獲得這個藍色邊框，而不僅僅是復選框本身。
我試圖在觸發 wrappanelmyCheckbox.Focus();時呼叫MouseEnter，但沒有成功。
而且我還看到了關于如何在呼叫 CheckBox.Focus() 時出現復選框焦點邊框的鏈接，但它也不包含解決方案。
任何幫助表示贊賞。

修改模板CheckBox以使用 aWrapPanel而不是默認的Grid：

如果您對替代（更簡單）解決方案持開放態度，那么您應該這樣做：為復選框定義自定義樣式并覆寫模板，以便讓 WrapPanel 和您想要的任何控制元件都成為 CheckBox 的一部分。
<Style TargetType="{x:Type CheckBox}" x:Key="myCheckboxStyle">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type CheckBox}">
<WrapPanel>
<Label />
<!-- other Controls -->
<ContentPresenter/>
</WrapPanel>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
將自定義樣式應用于復選框
<CheckBox Style="{StaticResource myCheckboxStyle}" Content="Check Me"/>
