Hello - 

I’m new to AJAX and going through an example in a book. It’s a very simple exercise which I was hoping to evolve into something real-world. 

Problem is my panel know as pnlConfirmation is not being displayed once the timer runs out.  When I click the button and fire the event, the UpdateProgress panel does show as expected but once it’s done, pnlConfirmation is not displayed.
 I was hoping for a second set of eyes to point of the obvious error.  Thanks!!

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <asp:Panel ID="pnlForm" runat="server">
            <br /><br />
            <asp:Button ID="Button1" runat="server" Text="Do something awesome" OnClick="Button1_Click" />
            </asp:Panel>
        </ContentTemplate>
    </asp:UpdatePanel>


    <asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
        <ProgressTemplate>
            <asp:Panel ID="pnlProgress" runat="server">
            <br /><br />
            Doing something awesome now.....
            <br /><br />
            </asp:Panel>
        </ProgressTemplate>
    </asp:UpdateProgress>
   

     <asp:Panel ID="pnlConfirmation" runat="server" Visible="False">
        <br /><br />
         Something awesome was done.
        <br /><br />
     </asp:Panel>

…and…the button’s click event (C#):

    protected void Button1_Click(object sender, EventArgs e)
    {
        
        pnlConfirmation.Visible = true;
        pnlForm.Visible = false;
        System.Threading.Thread.Sleep(5000);

    }

What am I doing wrong?

The panel needs to be inside the updatepanel contenttemplate. 

Thanks but that didn’t seem to make a difference.  Like this?

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <asp:Panel ID="pnlForm" runat="server">
            <br /><br />
            <asp:Button ID="Button1" runat="server" Text="Do something awesome" OnClick="Button1_Click" />
            </asp:Panel>

             <asp:Panel ID="Panel1" runat="server" Visible="False">
                <br /><br />
                 Something awesome was done.
                <br /><br />
             </asp:Panel>

        </ContentTemplate>
    </asp:UpdatePanel>


    <asp:UpdateProgress ID="UpdateProgress1" runat="server" AssociatedUpdatePanelID="UpdatePanel1">
        <ProgressTemplate>
            <asp:Panel ID="pnlProgress" runat="server">
            <br /><br />
            Doing something awesome now.....
            <br /><br />
            </asp:Panel>
        </ProgressTemplate>
    </asp:UpdateProgress>

You now have Panel1; this was pnlConfirmation.

<facepalm />

Thanks!
