从组合框中选择文本 [英] Select text from combobox

问题描述

我有一个简单的问题:

我在WPF中有一个组合框，但我希望用户能够将文本从其中复制到剪贴板.因此，选择所选项目的显示文本，然后右键单击copy或ctrl + c.就像默认的Windows行为一样.

I have a combobox in WPF, but i want users to be able to copy the text from it to the clipboard. So select the displayed text of the selected item and right-click copy or ctrl+c. Just like default windows behaviour.

<ComboBox 
    ItemsSource="{Binding Products}" 
    DisplayMemberPath="ProductName"
    IsEditable="True"                               
    SelectedItem="{Binding SelectedStroomProduct}">
</ComboBox>

如何在不使用代码的后面或旁边放置or脚的按钮的情况下做到这一点?

How can i do that without using code behind or putting a lame button next to it?

推荐答案

除非您采取特殊措施以吞下鼠标单击事件和键盘输入事件，否则可编辑组合框中的文本框将支持带有剪贴板命令(包括加速键快捷方式)的上下文菜单如 Ctrl + C .因此，基本上简单地将< ComboBox> 放在具有 IsEditable ="True" 的WPF窗口上就不会表现出您描述的行为.

Unless you do something special to swallow mouse click events and keyboard input events the text box inside the editable combo box will support a context menu with clipboard commands including accelerator shortcuts like Ctrl+C. So basically simply putting a <ComboBox> on a WPF window having IsEditable="True" does not exhibit the behavior you describe.
