Hi Martin,
Thank you for writing.
With this setup, the drop downs will contain items and each item Value will be whatever is contained in the following property:
So, if you assign the SelectedValue with a valid ID, contained in the control it should get selected. I have tested this with the following example:
I cannot think of a reason for the drop down's to have its SelectedValue == null, if a proper ID is assigned.
Should you continue to experience this undesired behavior I would kindly ask you to create a small sample project where the issue can be reproduced and get back to me with it, so I can investigate the precise case and help you resolve it. In addition, please include a description of the steps that I need to take in order to reproduce the experienced issue.
I am looking forward to your reply.
Regards,
Stefan
