Hi guys,

I want to do a very simple thing, can you point me on the right direction?

I want to change the source in XAML to another object source, let me put you an example:

• I have a Listview, bound to a "Model A", it has many properties, but one is called "Total". This property is not shown on the View
• Each ListviewItem has its own source (ItemsSource), BUT, one of the fields should show "Total" from "Model A"

Caveat: I am implementing MVVM, so the "Model A" is assigned as a VM DataSource, XAML knows nothing about it.

So, in my perfect world the XAML should look like this:

<GridViewColumn Header="Total" Width="150">
   <GridViewColumn.CellTemplate>
      <DataTemplate>
         <Label Content="{Binding Source=<The source of LISTVIEW> Path=Total}"/>
      </DataTemplate>
    </GridViewColumn.CellTemplate>
 </GridViewColumn>

I have tried RelativeSource but that points me to the XAML object, I want the source of it, is it possible?

Thanks
