I have 1 parent form call 1 child form by using :

        Context.Items["pplId"] = DetailsView1.SelectedValue.ToString();
        Server.Transfer("cusAdd.aspx");

In Child Form (cusAdd.aspx), have an ObjectDataSource.

How to configure the ObjectDataSource SelectParameters Source from context.items["pplId"]?

 <asp:ObjectDataSource ID="odsCusById" runat="server" 
        SelectMethod="GetPplById" TypeName="pplBLL"
        <SelectParameters>
            <asp:QueryStringParameter DefaultValue="0" Name="id" ...... <------------------------------------??????????????
        </SelectParameters>

TIA.
