Hi Mona -- you should be able to architect your user control so that you can pass the data into it instead of having the data access inside it. You should consolidate your data management in one place.

Hi Pam -- You should be able to create a control template for the WPF data grid that contains the same type of lookup controls as shown above.

Please Beth - precisely the same data scenario as above - how do I make this work for a datagridcombobox where there is no SelectedItem Property? Thanks your help.

Thank you for this great post. I now understand that I have to use the same Object Context to query lookup table with entity framework. But I have a problem. I have a page with the info on the orders, but the info on the customer is in a UserControl. So my ComboBox is in that control. I created a two collection view on my page "OrdersSource" and "CustomerLookup" but I don't know how to get "CustomerLookup" from my comboBox in my userControl. If I use ItemsSource="{Binding Source={StaticResource CustomerLookup}}" it doesn't find it. I can't use DynamicResource. And if I try with RelativeSource FindAncestor it says it can't find "PROPERTY" CustomerLookup. Any ideas how can I resolve this? Thank you!

Thank you so much, Beth, for ItemsSource to be used with Entity Framework, I was getting mad to try to make working EF with SelectedValuePath and SelectedValue. And I can say that I've search unfortunately this in many blog before find the correct way to do in your very clear one. I put your blog in my favourites ! Merci beaucoup !
