Place a RadComboBox control in a RadPane. Make it floating and dock it again. When selection is changed, the SelectionChanged event is fired multiple times.
IsEditable=True and ReadOnly=True
RadComboBox with IsEditable = true, IsReadOnly = true and IsFilteringEnabled = true. Select an item and then in order for the filtering to work you have to delete the selected text with Backspace
Allow the developers to style the TextBox area of a editable RadComboBox - add icons, change the string, format the text etc.
When the ComboBox is non editable.
When IsEditable is set to true the SelectedItem is not updated if you delete the SelectedItem's text to match another existing item.
