推荐答案

通常您可以单击任意位置将其打开.我不想那样.

Usually you can click anywhere to open it. I dont want that.

然后您应该为 ToggleButton 创建一个自定义模板.Yan 在 Visual Studio 或 Blend 中的设计模式下右键单击 ComboBox 元素，然后选择编辑模板"->编辑副本".

Then you should create a custom template for the ToggleButton. Yan right-click on the a ComboBox element in design mode in Visual Studio or in Blend and choose Edit Template->Edit a copy.

这会将默认模板复制到您的 XAML 标记中，然后您可以根据需要对其进行编辑.寻找一个 x:Key 为 "ComboBoxToggleButton" 的 Style 并修改它的 ControlTemplate.

This will copy the default template into your XAML markup and you can then edit it as per your requirements. Look for a Style with an x:Key of "ComboBoxToggleButton" and modify the ControlTemplate of this one.
