有关更多详细信息,我正在使用 mvvm light,当我单击透明按钮时,命令会触发,但不会触发其他颜色(命令中未到达断点).谢谢你的帮助:)

推荐答案
按钮在边框内并且不可见"
The button is inside the border and "invisible"
要获得圆形按钮(或矩形以外的其他形状),您需要更改按钮本身的模板.
To get a round button (or another shape other than rectangular), you need to change the template of the button itself.
这是一个完整的圆形按钮模板示例.将其记录在资源字典中并在您的按钮中使用.
Here's an example of a FULL circular button template. Record it in a resource dictionary and use it in your button.
我没有设置颜色绑定,因为我从你的代码中不明白它们在哪里使用.
I did not set color bindings, because I did not understand from your code where they are used.
<SolidColorBrush x:Key="Button.Static.Background" Color="#FFDDDDDD"/>
<SolidColorBrush x:Key="Button.Static.Border" Color="#FF707070"/>

<SolidColorBrush x:Key="Button.MouseOver.Border" Color="#FF3C7FB1"/>

所有的key都是通过DynamicResource获取的.因此,它们可以在应用模板的地方重新定义.
All keys are obtained through DynamicResource. Therefore, they can be redefined at the place where the template is applied.

用完整的 XAML 代码补充问题后,如果我理解正确,我展示的模式应用如下:
After complementing the question with the complete XAML code, if I understood it correctly, the pattern I showed is applied like this:
<Button Content="{Binding}" Tag="{Binding Name}"
Height="130" Width="130" Margin="0"
Click="Button_Click">
<Button.Resources>
<SolidColorBrush x:Key="Button.MouseOver.Border" Color="Gray"/>
