Help with ASP.NET UpdatePanel control!!!

[Todd Carter]

Ok, I'm having a little difficulty with the ASP.net updatepanel control. I have it all hooked up and it is posting back to the server correctly, but the problem I am having is it will not update the innerHTML of a div tag. I'm thinking I have seen this done before.

Here is the client-side code:

<asp:UpdatePanel runat="server" ID="UpdatePanel2" EnableViewState="true" UpdateMode="Conditional" >
        <ContentTemplate>
            <p>Please verify your information is correct, then click the <br />"Confirm" button continue with your enrollment."</p>
            <div id="message" runat="server" style="color:Red;"></div>
            <table>
                <tr>
                    <td>Name:</td>
                    <td><asp:Label ID="fullNameLabel" runat="server"></asp:Label></td>
                </tr>
                <tr>
                    <td>SSN:</td>
                    <td><asp:Label ID="ssnLabel" runat="server"></asp:Label></td>
                </tr>
                <tr>
                    <td>Gender:</td>
                    <td><asp:Label ID="genderLabel" runat="server"></asp:Label></td>
                </tr>
                <tr>
                    <td>DOB:</td>
                    <td><asp:Label ID="dobLabel" runat="server"></asp:Label></td>
                </tr>
                <tr>
                    <td>Birth State:</td>
                    <td><asp:Label ID="birthStateLabel" runat="server"></asp:Label></td>
                </tr>
                <tr>
                    <td>Marital Status:</td>
                    <td><asp:Label ID="maritalStatusLabel" runat="server"></asp:Label></td>
                </tr>
                <tr>
                    <td>Address:</td>
                    <td>
                        <asp:Textbox ID="address1Label" runat="server" MaxLength="50"></asp:Textbox>
                    </td>
                </tr>
                <tr>
                    <td>&nbsp;</td>
                    <td>
                        <asp:Textbox ID="address2Label" runat="server" MaxLength="50"></asp:Textbox>
                    </td>
                </tr>
                <tr>
                    <td>City:</td>
                    <td>
                        <asp:Textbox ID="cityLabel" runat="server" MaxLength="50"></asp:Textbox>
                    </td>
                </tr>
                <tr>
                    <td>State:</td>
                    <td><asp:Label ID="stateLabel" runat="server"></asp:Label></td>
                </tr>
                <tr>
                    <td>Zip:</td>
                    <td>
                        <asp:Textbox ID="zipLabel" runat="server" MaxLength="10"></asp:Textbox>

                </tr>
                <tr>
                    <td>Country:</td>
                    <td><asp:Label ID="countryLabel" runat="server"></asp:Label></td>
                </tr>
                <tr>
                    <td>Home Phone:</td>
                    <td>
                        <asp:Textbox ID="homePhoneLabel" runat="server" MaxLength="10"></asp:Textbox>
                    </td>
                </tr>
                <tr>
                    <td>Cell Phone:</td>
                    <td>
                        <asp:Textbox ID="cellPhoneLabel" runat="server" MaxLength="10"></asp:Textbox>
                    </td>
                </tr>
                <tr>
                    <td>Work Phone:</td>
                    <td>
                        <asp:Textbox ID="workPhoneLabel" runat="server" MaxLength="10"></asp:Textbox>
                    </td>
                </tr>
                <tr>
                    <td>Work Phone Ext:</td>
                    <td>
                        <asp:Textbox ID="workPhoneExtLabel" runat="server" MaxLength="5"></asp:Textbox>
                    </td>
                </tr>
                <tr>
                <tr>
                    <td>Email Address:</td>
                    <td>
                        <asp:Textbox ID="emailAddressLabel" runat="server" MaxLength="150"></asp:Textbox>
                    </td>
                </tr>
                <tr>
                    <td colspan="2" style="text-align:right;">
                        <asp:Button ID="confirmButton" runat="server" Text="Confirm" CssClass="button" />
                    </td>
                </tr>
            </table>
        </ContentTemplate>
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="enrollNowButton" EventName="Click" />
        </Triggers>
    </asp:UpdatePanel>

Here is the server-side code:

 Protected Sub confirmButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles confirmButton.Click
        If String.IsNullOrEmpty(Me.address1Label.Text) Then
            message.InnerHtml = "Address is required! Please enter your address."
            message.Style("display") = ""
            'UpdatePanel2.Update()
        End If
        If String.IsNullOrEmpty(Me.cityLabel.Text) Then
            message.InnerHtml = "Address is required! Please enter your address."
            message.Style("display") = ""
            'UpdatePanel2.Update()
        End If
        If String.IsNullOrEmpty(Me.zipLabel.Text) Then
            message.InnerHtml = "Address is required! Please enter your address."
            message.Style("display") = ""
            'UpdatePanel2.Update()
        End If
        If String.IsNullOrEmpty(workPhoneLabel.Text) Then
            message.InnerHtml = "Address is required! Please enter your address."
            message.Style("display") = ""
            'UpdatePanel2.Update()
        End If

    End Sub

Any help with this would be appreciated.
