Have a picker with ViewModel, populated by a Web Service (the Picker is populated by an object, that contains PolicyName, PolicyID and Description. What I want to do is be able to select the item in the Picker by the Value (ie PolicyName), not by SelectedIndex. Originally I thought I be able to use the SelectedItem (OnChangeProperty) I use in the ViewModel that I use to get the SelectedItem that the user selects. But this time, I need the ability to set SelectedItem.
Thoughts? Or I didn't explain myself too well?
