I have a plain "Location" object with a list of string properties (City, Country, Zip, etc.) I want to display, underneath headers of the name of the property. What I've got now works, and looks like this:

<TextBlock Text="City" Style="StaticResource HeaderStyle" />
<TextBlock Text="Binding City" />
<TextBlock Text="Country" Style="StaticResource HeaderStyle" />
<TextBlock Text="Binding Country" />

… and so on. The header text happens to be the same as the property path, and naturally I want to avoid duplicating writing all these pairs of TextBlocks and instead use an ItemsControl and DataTemplates.

I've defined a list of strings in my Window.Resources, and have an ItemsControl displaying at least the headers correctly, but I can't use a dynamic value for a binding path:

<Window.Resources>
 <x:Array x:Key="LocationKeys" Type="sys:String">
 <sys:String>City</sys:String>
 <sys:String>Country</sys:String>
 <sys:String>Zip</sys:String>
 </x:Array>
</Window.Resources>

...

<ItemsControl ItemsSource="StaticResource LocationKeys">
 <ItemsControl.ItemTemplate>
 <DataTemplate>
 <StackPanel>
 <TextBlock Text="Binding" Style="StaticResource HeaderStyle" />
 <TextBlock Text="Binding Path=Obviously I can't do this" />
 </StackPanel>
 </DataTemplate>
 </ItemsControl.ItemTemplate>
<ItemsControl>

So close! I can't shake the feeling that I'm missing something here, and I'm having enough trouble finding the terms to search for to find someone with the same problem - all the hits I'm getting so far for 'Dynamic binding path' etc. are usually trying to solve another problem that's quite different.

Am I missing something easy? Is there a better way?

Your view model may contain a dictionary like

public class ViewModel

 public Dictionary<string, object> Locations get; 
 = new Dictionary<string, object>();

to which you would bind like this:

<ItemsControl ItemsSource="Binding Locations">
 <ItemsControl.ItemTemplate>
 <DataTemplate>
 <StackPanel Orientation="Horizontal">
 <TextBlock Text="Binding Key" Width="100"/>
 <ContentControl Content="Binding Value"/>
 </StackPanel>
 </DataTemplate>
 </ItemsControl.ItemTemplate>
</ItemsControl>
