Very odd issue with Formview in VS2008.

Envrionment: Sql 2005, VS2008, VB.NET
Setting: Formview bound to a sqldatasource. Has an embedded fileupload control. Clicking on insert fires the upload of the selected file to the database - works fine. However, I need to pass several other fields from the datasource to the table with the file. (definitions in code windows).  

If you look at the code_behind coding, the two fields associated with the fileupload control (attachname and attachfile) get posted to the table. The remaining fields don't get passed, regardless of whether they are set to variables, defaults or constant. Not sure what is going on.
 
Formview insert template:

                                        <InsertItemTemplate>
                                            File Name:
                                            <asp:TextBox ID="AttachNameTextBox" runat="server" Text='<%# Bind("AttachName") %>' />
                                            &nbsp; File: &nbsp;
                                            <asp:TextBox ID="WorkOrderIDTextBox" runat="server" Text='<%# Bind("WorkOrderID") %>'
                                                Visible="false" />
                                            <asp:TextBox ID="DocLinkNoTextBox" runat="server" Text='<%# Bind("DocLinkNo") %>'
                                                Visible="False" />
                                            <asp:TextBox ID="AttachDateTextBox" runat="server" Text='<%# Bind("AttachDate") %>'
                                                Visible="False" />
                                            <asp:TextBox ID="AttachByTextBox" runat="server" Text='<%# Bind("AttachBy") %>' Visible="False" />

                                            <br />
                                            <asp:LinkButton ID="InsertButton" runat="server" CausesValidation="True" CommandName="Insert"
                                                Text="Upload File" />
                                            &nbsp;<asp:LinkButton ID="InsertCancelButton" runat="server" CausesValidation="False"

may be you might want to try OnInserting of SqlDataSource to set parameter value like
e.Command.Parameters("@AttachDate").Value = DateTime.Now

Thanks!!! That worked very nicely. Curious as to why the first version didn't work - would have though the parameters were sent either way.

Much appreciated!

I don't have exact idea...but in the second case you are dealing directly with the parameters before the command will be executed.
