Hey,

What are you binding the original list against? Let's say you are binding a list; you can always do the following to do that type of operation:

MMBRSODS.UpdateParameters["UserName"].DefaultValue = list.SelectedValue;
MMBRSODS.Update();

So supplying the default value allows you to still use the update, the param relies on this default and supplies it to the backend... what control are you using to show the data?

HTH.
