Master-Details with GridView and FormView and Paging

[ThePurpleCat]

Hi, I'm a newbie to ASP.NET programming but not to Visual Studio.

I'm having trouble getting my Master-Details page to work. I have a
page enabled GridView which is linked to a FormView control through an
objectdatasourc e. The paging on my GridView works fine except that when
I change the page the FormView
does not update. I tried setting the selectedindex to 0 in the
GridView's PageIndexChange d event and manually binding the formview but
the selectedvalue that the function sees is the old value from
the page being changed from and not the new page so the FormView
refreshes with the wrong value. I also bind the formview on pageload
but that doesn't work either. What am I doing wrong? Here's my
code-behind, followed by the form script...

Protected Sub Page_Load(ByVal sender As Object, ByVal e As
System.EventArg s) Handles Me.Load

If Not IsNothing(Me.gv wProducts.Selec tedValue) Then
Me.fvwCurrentPr oduct.DataBind( )
End If

End Sub

Protected Sub gvwProducts_Pag eIndexChanged(B yVal sender As
Object, ByVal e As System.EventArg s) Handles
gvwProducts.Pag eIndexChanged
Me.gvwProducts. SelectedIndex = 0
fvwCurrentProdu ct.DataBind()
End Sub
