WPF中的复选框模板

Question

我在正在开发的应用程序中遇到了一种情况。我想为一个复选框编写一个模板，我应该能够只禁用勾选标记框并保持标签启用。这真的可以吗。我想出了一个模板，但是当我禁用复选框时，标签和刻度线都被禁用了。

看看这个 xaml

Answer 2

我遇到了同样的问题并想出了一个非常愚蠢的解决方案：

<StackPanel  Orientation="Vertical"  >
        <TextBlock Text="Set Global Edition" TextWrapping="Wrap" HorizontalAlignment="Center" />
        <CheckBox x:Name="GlobalEdition" IsChecked="{Binding IsGlobal}" HorizontalAlignment="Center" />
</StackPanel>

由于 TextBlock 和 Checkbox 是分开的，因此更改 Checkbox 状态不会影响附加到它的文本。

（如果我没记错的话，如果禁用 Textbox 并不会改变其外观，也许你可以尝试使用 TextBox 而不是标签）
