WPF ComboBox default ControlTemplate
提问by Stefan Fachmann
Where to find the default ComboBox ControlTemplate?
Is there any tool to extract it from a ComboBoxinstance?
All I've found is a ComboBox ControlTemplateexample, which is completely different from the default one.
在哪里可以找到默认值ComboBox ControlTemplate？是否有任何工具可以从ComboBox实例中提取它？我发现的只是一个ComboBox ControlTemplate例子，它与默认的完全不同。
回答by Mark
In the Designer -> Right Click the ComboBox -> Edit Template -> Edit a Copy
在设计器中 -> 右键单击组合框 -> 编辑模板 -> 编辑副本
