    I have a RadComboBox bound to an ObservableCollection. The collection is modified and cleared pragmatically (via various user interactions).

    I'm looking for a XAML friendly solution that will set the SelectedIndex to 0 when going from no items (no selection) to having items.

    I've tried simply setting SelectedIndex=0 but that doesn't work. (I get no selection).

    Hi Mike,

    Unfortunately if you change the ItemsSource of the control you will need to set the SelectedIndex in the code behind. The initially declared in the xaml SelectedIndex gets reset because it is associated with old ItemsSource.
