I have a number of combo boxes in a window that I need to setup two-way binding on, however I can't seem to figure out how to do it. I have successfully set up basic binding to fill the control where I have the ItemsSource="{Binding}" and I set my DataContext in my C# code behind. I also have two-way binding working on all of the other controls in the window
Let's say I have an object and I am returning an ObservableCollection of it and I want to display Name which is a string. I want the value member to be an ID which is an integer. Is there a code snipped you can please provide that shows how to do two way binding on the ID? I can't seem to find a ValueMember property anywhere, and basically XamComboBox binding is a mystery for me.
Thank you for a very simple and basic xaml code snippet.
Hello Mike,
Thank you for the clarification and the sample code that you have posted. I have looked into it and I assume that you are using the shared XamComboEditor, which is available in both WPF and Silverlight. If my assumption is correct, you can use the SelectedItem in order to bind the name of the selected item form the XamComboEditor to the Text property of the TextBox, since the XamComboEditor which comes from the Silverlight does not currently expose ValuePath property. I have used the sample code that you have posted and created a sample application in which you can change the Name of the selected Clinic from the TextBox.
If you need any further assistance on the matter please do not hesitate to ask.

Krasimir,
Thank you for your sample project, but it is not what I was looking for. Maybe I have not been explaining this in a good way, so let me take a step back and try again. Also I made a mistake and grabbed the composite control, and I meant to use the WPF XamComboEditor, please excuse.
I have a user control with a number of edit controls and XamComboEditor controls. This is a detail window for a patient. I have bound the user control's grid to a Patient object and then did two-way binding between each TextBox and the appropriate property in the Patient object. This all works great.
Next I have several combo boxes that I have filled with information. An example of one of these would be Clinics (I have several others). I have populated all combo boxes when the window inits so they are all filled by the time I bind my Patient object. In filling my combo boxs, I have the ItemsSource="{Binding}" and set their DataContext to an ObservableCollection.
What I am looking to do is if the selected item in a combo box changes, the patient object will be updated through two-way binding as with the text controls. I am new to WPF and binding, and with windows forms, I would have trapped the selection changed event and made the change in there. However I am wondering if there is a way to do this with binding the combo boxes selected item event to the Patient object? Or is it because I have bound the combo boxes to the lists that originally populated them, two-way binding to the Patient object is not possible and I have to take another step in there to make it happen.
Thanks.
Krasimir, Are you still able to help me with this issue?
Thanks,
Mike
