using object to load dropdown error is It must be either an IListSource IEnumerable or IDataSource.

Question

What syntax do I use to load dropdown with an object?

IE I have a class "project". The method "LoadAll" loads "project" with thirty projects

Project object has a idProject parameter and a projectName

project objProj = new project();
objProj.LoadAll();

            DropDownList ddTemp = new DropDownList();

            ddTemp.DataSource = objProj;
            ddTemp.DataValueField = "idProject";
            ddTemp.DataTextField = "projectName";
            ddTemp.DataBind();

error is "It must be either an IListSource, IEnumerable, or IDataSource".

I wrote a method that loads a datatable from the object parameters. I thought that the object was array storage but had to load from database directly. The writing was a bit obscure and required a closer look. Thank you for your assistance.

You really need to bind to to an array or List of projects as these collections implement IEnumerable. It seems an odd situation that a project object should load 30 more :-/ How would you access those 30 projects? Are they held in an array internally?
