I have looked at some of the other linked related articles but I still can't get it.
Simply I have 2 related tables Orders and Customers
when I am editing an order I want to display the Customer in a Combobox.
Let's say I wish to change the customer using a cbo
The Customer Combo box should be populated with all Customers from the customer table
the currently selected customer should be the current customer in the Order Table for the Order I am Viewing
The display member should be the customers name
the tables are related with a CustomerID field in each table
The data is EDMX
I have done some work on databinding in WPF and I can get combo boxes populated with Data but it's just not quite there. I can't seem to get the selected cbo customer to update to the Orders
