Databinding ComboBox to GraphicsCollection

KeithGemeinhart

Greetings,

I'd like to bind a GraphicsCollection (which is a property in a view model) to a combo box in a XAML window. The problem is I can't figure out how to display attribute values in the combo box. I can get it to display the Geometry property like this:

<ComboBox DataContext="{StaticResource MyViewModel}"                 DisplayMemberPath="Geometry"                 ItemsSource="{Binding CollectionOfGraphics}"  />

But I want to be able to do something like this that will display the OBJECTID or some other attribute:

<ComboBox DataContext="{StaticResource MyViewModel}"                 DisplayMemberPath="Attributes[&quot;OBJECTID&quot;]"                 ItemsSource="{Binding CollectionOfGraphics}"  />

I also tried this approach - unsuccessfully:

<ComboBox DataContext="{StaticResource MyViewModel}"                 DisplayMemberPath="Attributes[0]"                 ItemsSource="{Binding CollectionOfGraphics}"  />
