Hi Ashley Murray,
With RadComboBox Prometheus you should be able to use the SelectedValue
property to obtain the value of the selected item even in a callback mode. What does the SelectedValue
property return in your case?
To set an initial value/text you can use the set_value
methods of the combobox objects. You can hook on the client-side onload
event of the page (<body onload="...">) and call the methods in the event handler.
