How change a DetailsView Datafield Value to a Hidden Value on Update

Hi Experts,

I need to change the value of a Bound DataField in a DetailsView.  I select the SQL record that includes a field of who last changed the record (this need not be included in the DetailsView).  When someone edits and updates this record using the DetailsView, I need to pull their LOGON_USER value and insert it into this field of the new row of the SQL table.

I can do all of this in a regular .asp form, but I seem to be lost in asp.net 2.0.  I am using the GUI to create the DetailsView and I can edit the DataSet if needed. If code-behind is needed, I do not really understand this concept yet (I think it is a subroutine on the aspx.vb page, but how to call it???).  I have been working on this several days and really need to get past it.

Every help appreciated!

This code allows me to load data into a detailsview, change that data from a different source and then update the original source.  Be careful of AutoEventWireup="false" if trying to use code from aspx page instead of codebehind.

aspx page:  Pay attention to onitemupdating method, eval for showing data, bind for changing data

<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False" DataKeyNames="ServiceName,IsHistory"
                        DataSourceID="ObjectDataSource2" Height="50px" Width="100%" onitemupdating="StoresDetailView_ItemUpdating">
                        <Fields>

                            <asp:TemplateField HeaderText="ChangedBy" SortExpression="ChangedBy">
                                <itemtemplate>
                                    <asp:Label runat="server" Text='<% #Eval("ChangedBy") %>' />
                                </itemtemplate>
                                <EditItemTemplate>
                                    <asp:Label id="labelOne" runat="server" Text='<% #Bind("ChangedBy") %>' />
                                </EditItemTemplate>
                            </asp:TemplateField>


codebehind page:

    Sub StoresDetailView_ItemUpdating(ByVal sender As Object, ByVal e As DetailsViewUpdateEventArgs)

        Dim ChangedBy As String = GetChangedBy()
        e.NewValues("ChangedBy") = ChangedBy

    End Sub
    Function GetChangedBy() As String

        Dim ChangedBy As String

        ChangedBy = Request.ServerVariables("LOGON_USER")
        Return ChangedBy

    End Function
