Question

I am trying to bind programmatically the Content property of my WPF Button to a Dynamic Resource (Business Object) I have previously defined using a given Path. So far I tried the following approaches with no luck:

My Business Object is defined as a resource:

<Window.Resources>
   <env:PartyType x:Key="myParty" FullName="JOHN"/>
</Window.Resources>

I tried binding to my button programmatically like this:

        Binding binding = new Binding();
        binding.Source = this.Resources["myParty"];
        binding.Path = new PropertyPath("FullName");
        btn.SetBinding(ContentProperty, binding);

But apparently when I serialize to XAML its trying to serialize the whole Party Object, and I just want to keep a binding reference to my resource, so this option doesn’t work.
My second option was:

btn.SetResourceReference(ContentProperty,"myParty");

That gets serialized to XAML as:

<av:Button Content="{av:DynamicResource myParty}"/>

But I don’t know how to specify my Path=FullName so it can display the Party.FullName and not the Party.Type().

Any ideas on how to achieve this?

Thanks in advance,

Assign the dynamic resource to the DataContext and then create your binding without setting the Source property

btn.SetResourceReference(DataContextProperty,"myParty");

Binding binding = new Binding();
binding.Path = new PropertyPath("FullName");
btn.SetBinding(ContentProperty, binding);

Now if you already depand on the button’s DataContext, then you need set a Label as the button’s content and set the resource and binding on the label.
