Solution 1

try this:-
Use SessionParameter with SelectParameters to pass Session values

XML

<asp:SqlDataSource ID="SqlDataSource2" runat="server"
     ConnectionString="<%$ ConnectionStrings:yourConnection %>"
     SelectCommand="SELECT * FROM [examConfig]   WHERE [tchId]= @getTchId">
     <SelectParameters>
     <asp:SessionParameter Name="Name" SessionField="getTchId" Type="String" />
    </SelectParameters>
    </asp:SqlDataSource>
