Sorry for leaving this for so long but I've been thinking about this issue more. Let me elaborate.
We have a number of combo boxes in the system whose values come from database tables. These tables allow users to inactive rows which may not be used commonly anymore. However, some records inevitably exist that are still linked to these inactive values. Furthermore, currently, we limit the items in these ComboBoxes to only active records. Therefore, there are cases where a previously saved record exists that uses one of these inactive values and upon displaying the record the combo box appears empty.
So then, we are attempting to find a solution to this issue. My main frustration so far is that it does not appear that the RadComboBox even attempts to select the value in any of the user-accessible overrides/event handlers; no selection changed logic ever hits a breakpoint for ComboBoxes that exhibit this issue. It seems that what needs to occur on our end is for us to be able to identify this occurrence and automatically add an item that corresponds to this saved inactive value. But again, I don't see a way to tie into the control in any way to currently handle that case.
Everything make sense?
