Question

I have a listbox that is displaying several attributes from an XML file. How can I update a textbox whenever you select one of these items on the listbox? My listbox looks like this:

<ListBox Name="RouterSelection" ItemsSource="{Binding Source={StaticResource RoutingData}, XPath=Routes/Route/IdClient}"/>

and my textbox looks like this:

<TextBox DataContext="{Binding ElementName=RouterSelection, Path=SelectedItem}" Text="{Binding XPath=@Value}"/> 

But the textbox is not showing the content when you select any of the items. What am I missing? Thanks for any help!

Answer 1

Try

<TextBox Text="{Binding ElementName=RouterSelection, Path=SelectedValue}"/> 

and set SelectedValuePath for ListBox
