Thanks for lead in there. It didn't work but I keep plugging away at the control!

I know have these line:
Session["dsGetModels"] = dsGetModels;
MmDropDownList2.DataSource = dsGetModels;
MmDropDownList2.DataBind() ;

And I get :
System.Data.DataRowView in my display.

I'm banging away at it. thanks again.
