Value from Sub Routine not being passed to parameter

I am trying to create a SUB in asp.net 2.0that will eventually update a fully editable grideview. However when i try this i get a no value for parameters error on this line dsoTithe.Update()


Sub Updatedb(ByVal sender As Object, ByVal e As EventArgs)
Dim dgi As GridViewRow
For Each dgi In GridView1.Rows
'Read in the Primary Key Field
Dim id As Integer = (GridView1.DataKeys(dgi.RowIndex).Value.ToString())
Dim Titheup As Double = CType(dgi.FindControl("TxtTithe"), TextBox).Text
'Call UPDATE statement...
dsoTithe.UpdateParameters.Clear()
dsoTithe.Update()

Next
End Sub

<asp:AccessDataSource ID="dsoTithe" runat="server" DataFile="~/App_Data/tithe/GBCTITHE.MDB"
UpdateCommand="UPDATE Tithe SET Tithe=? Where trid=?">
<updateparameters>
<asp:controlparameter name="Titheparam" controlid="Updatedb" propertyname="Titheup"/>
<asp:controlparameter name="TRIdparam" controlid="Updatedb" propertyname="id"/> </updateparameters>
</asp:AccessDataSource>

 

Is there a URL that we can see the error?
