If the formView isn't drawn, then it shouldn't be calling the
DataBound event, since it has no data.
If you want to force the form view to appear, you need to simulate the
selection on the Gridview when the page loads. The code will then act
as if a user has selected a specific row in the GridView.
This actually sounds like a mode issue, ie. you only want to do this
when your FormView is in edit mode, so you'd wrap the code like so..
if FormView1.CurrentMode = FormViewMode.Edit then
'Fill my dropdown
End if
