Question

I cannot set the default combobox selected value for an unbound combobox. Here is my code:

         System.Console.WriteLine("Current Tag Org Id = " + CurrentTag.Org.OrgId);
         ddlRUC.SelectedValue = CurrentTag.Org.OrgId;
         System.Console.WriteLine("ddlRUC selected value = " + ddlRUC.SelectedValue);

Here is the output:
Current Tag Org Id = 285
ddlRUC selected value =

Note that ddlRUC.SelectedValue has not been set to 285. Does the datasource need to be bound in order to use the SelectedValue property? If so, how do I set the default item shown in a combobox that is not bound?

Answer 1

The SelectedValue property will only work for a databound listbox. If you can create your list items in a List<>, you can then bind the list to the control and SelectedValue will work as you would like.
