工具栏中的Combobox行为不同 [英] Combobox in toolbar behaves differently

问题描述

从 this 主题开始提出新问题，任何人都可以回答为什么 ComboBox 与 CheckBox es在工具栏内外会有不同的行为？

来自链接问题的摘要：

我注意到，当ComboBox放置在工具栏中时，会有不同的行为。当不在工具栏中时，它的行为如预期的：复选框更改状态，而不关闭弹出窗口。但在ToolBar中，弹出窗口会在第一次点击时关闭，而不管点击在哪里。请尝试新的代码。我真的需要这个工具栏。

解决方案

我想感谢jberger建议我去MS。 >

如 ，解决方案是将 CheckBox.Focusable 属性设置为 False

 < DataTemplate DataType =MyDataClass> 
< CheckBox Focusable =False... /> 
< TextBlock ... /> 
< / DataTemplate> 
  

这提供了 ComboBox 是在工具栏或只是漂浮在一些面板。

Starting a new question from this thread, Can anyone answer why a ComboBox with CheckBoxes would behave differently inside and outside of a toolbar?

Summary from linked question:

I noticed that there is a difference of behavior when the ComboBox is placed in a Toolbar. When not in the Toolbar, it behaves as expected: the CheckBox changes state without closing the Popup. But in the ToolBar, the Popup closes on the first click, regardless of where the click is. Try the new code, please. I really need this in a toolbar.

解决方案

I'd like to thank jberger for suggesting I go to MS.

As suggested by MS, the solution is to set the CheckBox.Focusable property to False in the template.

    <DataTemplate DataType="MyDataClass">
        <CheckBox Focusable="False" ... />
        <TextBlock ... />
    </DataTemplate>

This provides the desired behavior when the ComboBox is either in a ToolBar or just floating in some Panel.
