asp.net listview insert

Question

I am showing users for my website in a listview (bound to Membership.GetAllUsers()); this is working fine. I would like to allow users to be created via the listview as well (along with some workflow driven information I'll be storing in the Profile), so I have added an InsertLayoutTemplate. However I cannot seem to read the values from the insert template in the codebehind to actually get the information to update the users table in the database. I have tried handling ItemCommand and ItemInserting and searching for the control, and this works to a point - the control is found but the Text property is always blank.

The listview declaration is similar to below.

    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <asp:ListView ID="DataLV" runat="server" DataKeyNames="UserName" InsertItemPosition="LastItem">
                <ItemTemplate>
                    <tr style="background-color: #d0d0d0;">
                        <td>
                            <asp:Label ID="UserNameLbl" runat="server" Text='<%# Eval("UserName")%>'></asp:Label>
                        </td>
                    </tr>
                </ItemTemplate>
                <AlternatingItemTemplate>
                    <tr style="background-color: #f0f0f0;">
                        <td>
                            <asp:Label ID="UserNameLbl" runat="server" Text='<%# Eval("UserName")%>'></asp:Label>
                        </td>
                    </tr>
                </AlternatingItemTemplate>
                <InsertItemTemplate>
                    <tr style="background-color: #f0f0f0;">
                        <td>
                            <asp:TextBox ID="UserNameTB" runat="server"></asp:TextBox>
                        </td>
                    </tr>
                </InsertItemTemplate>
                <LayoutTemplate>
                    <table id="Table2" runat="server" width="100%">
                        <tr id="Tr1" runat="server">
                            <td id="Td1" runat="server">
                                <table id="itemPlaceholderContainer" runat="server" border="0" style="" width="100%">
                                    <tr id="itemPlaceholder" runat="server">
                                    </tr>
                                </table>
                            </td>
                        </tr>
                    </table>
                </LayoutTemplate>
            </asp:ListView>
        </ContentTemplate>
    </asp:UpdatePanel>

Answer 1

I tried without the updatepanel before posting, and ran into the same problem.

How can I check the information being passed back in the partial post-back?
