My question is regarding the solution on this page http://www.experts-exchange.com/Programming/Languages/C_Sharp/Q_25373688.html
I have implemented the solution but when I try to reference the controls after a postback they are not available.
Protected Sub bSearch_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles bSearch.Click
If nvddl1.SelectedValue <> "" Then id = nvddl1.SelectedValue
Gives the error Object reference not set to an instance of an object.
