Issue assigning a session variable to a sqldatasource

I have a sqldatasource that is running an update statement. The update statment calls a sproc that updates the table. I have a 'LastModifiedBy' column in the table. I set a session variable  (userid) to what I want to go into the this column in the page_load event to make sure it's being set. I setup the sqldatasource's parameters to use that session variable to send to the proc to populate the 'LastModifiedBy' column but it never gets sent. If I hardcode the variable in the proc, everything works fine.

Thoughts?

Are you sure the session variable exists at the point you use it? Do you check it for null to be use? Posting your code might be useful.

Pretty sure. However, since it's done declaratively, it's difficult to troubleshoot. Attached is the code. There is more but I think it's irrelavent. There is a 3rd party grid (infragistics) that invokes the update method. I do know the update method is being invoked so it should be out of the grid's hands at that point.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
        DeleteCommand="k_sp_Rules_D" DeleteCommandType="StoredProcedure" InsertCommand="k_sp_Rules_I"
        InsertCommandType="StoredProcedure" SelectCommand="k_sp_Rules_R" SelectCommandType="StoredProcedure"
        UpdateCommand="k_sp_Rules_U" UpdateCommandType="StoredProcedure" OnDeleted="SqlDataSource1_Deleted" OnUpdated="SqlDataSource1_Updated" OnUpdating="SqlDataSource1_Updating" OnInserted="SqlDataSource1_Inserted" OnInserting="SqlDataSource1_Inserting">
        <DeleteParameters>
            <asp:Parameter Name="product_rules_id" Type="Int32" />
            <asp:Parameter Name="original_product_rules_id" Type="Int32" />
        </DeleteParameters>
        <UpdateParameters>
            <asp:Parameter Direction="ReturnValue" Name="RETURN_VALUE" Type="Int32" />
            <asp:Parameter Name="product_rules_id" Type="Int32" />
            <asp:Parameter Name="original_product_rules_id" Type="Int32" />
            <asp:Parameter Name="supplier_im_id" Type="String" DefaultValue="" />
            <asp:Parameter Name="product_id" Type="String" />
            <asp:Parameter Name="company_id" Type="Int32" />
            <asp:Parameter Name="effective_date" Type="DateTime" />
            <asp:Parameter Name="base_cost" Type="Double" />
            <asp:Parameter Name="capability_support_cost" Type="Double" />
            <asp:Parameter Name="service_cost" Type="Double" />

            <asp:Parameter Name="unit_type" Type="String" />
            <asp:SessionParameter ConvertEmptyStringToNull="False" DefaultValue="" Name="LastModBy"
                SessionField="UserID" Size="15" Type="String" />
        </UpdateParameters>
        <InsertParameters>
            <asp:Parameter Name="supplier_im_id" Type="String" />
            <asp:Parameter Name="product_id" Type="String" />
            <asp:Parameter Name="company_id" Type="Int32" />
            <asp:Parameter Name="effective_date" Type="DateTime" />
            <asp:Parameter Name="base_cost" Type="Double" />
            <asp:Parameter Name="capability_support_cost" Type="Double" />
            <asp:Parameter Name="service_cost" Type="Double" />
            <asp:Parameter Name="cc_im" Type="String" />
            <asp:Parameter Name="cc_pct" Type="Double" />
            <asp:Parameter Name="qh_im" Type="String" />
            <asp:Parameter Name="qh_margin" Type="Double" />
            <asp:Parameter Name="qh_pct" Type="Double" />
            <asp:Parameter Name="active" Type="Boolean" />
            <asp:Parameter Name="unit_type" Type="String" />
            <asp:SessionParameter Name="LastModBy" SessionField="UserID" Type="String" />
        </InsertParameters>
        <SelectParameters>
            <asp:ControlParameter ControlID="txtDate" Name="dtEffectiveDate" PropertyName="Text"
                Type="DateTime" />
        </SelectParameters>
    </asp:SqlDataSource>
 
 
 
In code: 
    string pagename = "frmRule";
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            try
            {
                //fill header, body and footer labels
                GetPageContent(pagename, lblHeader, lblBody, lblFooter);
                txtDate.Text = System.DateTime.Now.ToShortDateString();
                Session["UserID"] = "test userid";
                
            }
            catch (Exception exp)
            {
                HandleError(exp, pagename, lblResult);
            }
        }
}

Found that if I changed one of the parameter's value in the grid's UpdateRow method to be what I wanted rather than the Update parameter value definition of the sqldatasource, the problem was corrected.

    protected void UltraWebGrid1_UpdateRow(object sender, RowEventArgs e)
    {
        //set the last mod by to be the user id
        e.Row.Cells[15].Value = Session["UserID"].ToString();
    }

Thanks!
