Select text from combobox

问题

I have a simple question:

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>

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

回答1:

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.
