上下文菜单，取决于列表框项目类型

Question

Is it good idea to select ContextMenu of ListBox item through Converter or is there some better way to do it?

Just to be clear I will describe my situation:

I have a Listbox control. As a ItemsSource of this Lisbox is ObservableCollection<MyClass>

I've set ContextMenu of ItemContainerStyle of the Listbox to look like this :

<Setter Property="ContextMenu" Value="{Binding Converter={StaticResource contextMenuConverter}}"/ >

In ContextMenuConverter I check some properties of MyClass class and select ContextMenu accordingly.

Answer 1

Uh, no, thats actually pretty good.

Another option would be to bind the SelectedItem to your ViewModel , bind the ContextMenu property to the same, and return a new ContextMenu whenever the SelectedItem is changed, based on the SelectedItem .

But, frankly, I like your solution more. Its cleaner.
