This happens only with editable ComboBox in Silverlight.
When the ItemsSource for a RadComboBox is bound to a collection with two different properties, id and ID. When I bind SelectedValuePath to one of the properties, changing selection throw error: "Ambiguous match found" exception.
When moving through elements(checkbox+ text) in RadCombobox with the keyboard, focus of combobox is not changed as expected. Sample project attached.
Add Events for when the ClearSelectionButton is clicked. onSelectionClearingEvent (cancelable preview event) OnSelectionClearedEvent This way we can easily handle the clearing of non-nullable datatypes
