I compile above code with asp.net 2 vbc.exe --> (vbc.exe /t:library /r:system.dll,system.data.dll,system.web.dll,system .xml.dll /out:bin/paging8.dll paging8.vb)
and everything is ok without any error and .dll create in /bin folder.
but when i call paging.aspx file in my browser then I give error

BC30456: 'Prev_Click' is not a member of 'ASP._2paging_aspx'.

Line 41: <asp:LinkButton id="btnPrev" Text="&lt; Previous Page" OnClick="Prev_Click" runat="server" />
