I dont think you can do this if the data is bound to a DataSet, I think you would need to load the items for the list and then manually add them to the list, obviously adding the "select" item first.

I'm not positive that this will work in a windows forms app, but here's how we do it in ASP.NET:

myControl.DataSource = myDataSet;
myControl.DataBind(); // <-- This isn't required in win forms.
myControl.Items.InsertAt(0, "-- Select --");

You should be able to do something similar in a winforms combo box.
