禁用时WPF切换按钮显示状态

我在WPF表单上有切换按钮,用于显示布尔值。

然而,这些应该显示其IsChecked状态,但它们都是未经检查的

我正在通过代码创建切换按钮,但“静态”切换按钮也存在问题

ToggleButton tb = new ToggleButton();

tb.Name = "btnRegisterR" + register + "P" + pos;
tb.Content = tuple.Item1";
tb.IsChecked = rnd.NextDouble() >= 0.5;
tb.IsEnabled = tuple.Item2;
tb.VerticalAlignment = VerticalAlignment.Top;
tb.HorizontalAlignment = HorizontalAlignment.Left;
tb.Height = 25;
tb.Width = 87;
tb.Margin = new Thickness(xPos, yPos, 0, 0);

registerGrid.Children.Add(tb);

编辑 :我不认为这是一个重复的链接问题,因为我不太期待禁用按钮上的互动,因为它看起来被禁用,但保持显示其状态。链接的问题只回答了功能部分,而我主要问的是造型部分。

编辑2 :为了进一步澄清,下面是我在一个旧的Winform应用程序中使用的内容,其中复选框的外观设置为“按钮”

您可以清楚地在视觉上区分启用或禁用的选项,同时仍然能够看到输入的状态(选中或未选中)。我只是尝试在WPF中复制这种显示行为,暂时没有成功,因为“选中|禁用”和“未选中|禁用”看起来与WPF切换按钮完全相同。

我最终在风格上使用了multitrigger使其工作。不知道这是否是最佳解决方案,但至少它给出了与winform相同的结果
