Can we attach domain data source (ria control) and also add items through code behind to one rad combo box in Silverlight?
I've attached domain data source to radcombobox in xaml & want to add one value i.e. "None" to radcombobox which is not in domain source.Is it possible ?
I tried it in domainsource_loadeddata event
radcombobox1.items.add("None");
but it is not added.I debug and found that radcombobox1.items.IsReadOnly property is true.I also tried to change it to false but it gives error.
Can anybody help me?
I need it in my project.
