RadGridView SelectedItem highlighting?

[Bradley]

I'm sure this is trivial, but I've been unable to find the answer.  I have a RadGridView defined as follows:

<telerik:RadGridView
    ItemsSource="{Binding Products}"
    SelectedItem="{Binding SelectedProduct, Mode=TwoWay}">
    ...
</telerik:RadGridView>

However, when I change the "SelectedProduct" programmatically, the RadGridView doesn't show that highlighting.  What am I doing wrong?

Hi Bradley, 

Can you share the implementation of your view model as well? The xaml looks ok but it does not give us a clue why this is not working. 

I am looking forward to your reply.
