I have two radcomboboxes. When radcombobox VendorType SelectedIndex fires, radcombobox Vendor is then populated in code by the value chosen in VendorType . Radcombobox Vendor loads fine in code until I add the properties for MarkFirstMatch, EnableLoadOnDemand, and EnableTextSelection to radcombobox Vendor . If I add these properties to the aspx page, then the radcombobox Vendor does not get loaded with the correct values on the selectedindexchange of radcombobox VendorType. If I do it in code after the radcombobox Vendor has done the binding or during the binding, radcombobox Vendor still does not get loaded with the correct values.
