I have a detailsview with 2 datakeynames, host_id and db_id. When I edit the registry I can modify the host_name, so I have to modify the host_id too. But when I update the host_id continue the same. I'm using stored procedures, and its right. what do i do?!?!?!?! Here is the code...

Private Sub sdsPrincipal_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEven tArgs)
For x As Integer = 0 To e.Command.Parameters.Count - 1
Trace.Write(e.Command.Parameters(x).ParameterName)
Trace.Write(e.Command.Parameters(x).Value)
Next


e.Command.Parameters("@HOST_ID").Value = e.Command.Parameters("@PRM_HOST_ID").Value
e.Command.Parameters.Remove(e.Command.Parameters(" @DB_DESC"))
e.Command.Parameters.Remove(e.Command.Parameters(" @HOST_ID"))
e.Command.Parameters.Remove(e.Command.Parameters(" @DB_VENDOR"))
e.Command.Parameters.Remove(e.Command.Parameters(" @DB_TYPE"))
e.Command.Parameters.Remove(e.Command.Parameters(" @DB_OBS"))

End Sub
