Mike,
You can change it programmatically by setting the .SelectedIndex. You'll see the change in the Combo when you do this, however, because it's databound, you also have to issue an .EndCurrentEdit() on the binding before it gets saved into your bound table.
this.MyCombo.SelectedIndex = 2;
this.BindingContext[this.MyTable].EndCurrentEdit();
Where MyTable is the DataTable where you've bound the .SelectedValue (not the DataSource of your Combo).

>How come when I fill the combobox by binding it to a datatable, I can't programatically change which item I want displayed? I tried changing .selectedtext, .selecteditem,
>.text, and using .FindStringExact, but I can't make it change the value.
