3 Different Ways to Display Progress in an ASP.NET AJAX Application
 
In this article, we will study three different techniques that allow you to visually display progress to users while performing partial-page updates using the UpdatePanel. For all the three approaches, I have used a .gif image to show a spinning gear kind of a progress bar while the UpdatePanel is performing some action. The image can be found with the source code for this article over here.
Method 1: Using PageRequestManager to display progress in an ASP.NET AJAX application
The PageRequestManager class handles the partial-page updates of the UpdatePanel. This class defines client events that you can use during an asynchronous request cycle. Let us see how to use some events of this class to display progress to the user while the UpdatePanel updates its contents.
Drag and drop a Button(btnInvoke) and Label(lblText) control inside the UpdatePanel. Also add a <div id="divImage" inside the UpdatePanel. This div will contain a .gif image that depicts progress and is initially set to invisible style="display:none". On the button click, perform a time consuming task. In our case, we have set a delay of 3 seconds by using Thread.Sleep(3000).  
C#
    protected void btnInvoke_Click(object sender, EventArgs e)
    {
        System.Threading.Thread.Sleep(3000);
        lblText.Text = "Processing completed";
    }
VB.NET
      Protected Sub btnInvoke_Click(ByVal sender As Object, ByVal e As EventArgs)
            System.Threading.Thread.Sleep(3000)
            lblText.Text = "Processing completed"
      End Sub
The markup and code for this sample is as shown below:

    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
         <script type="text/javascript">
             // Get the instance of PageRequestManager.
             var prm = Sys.WebForms.PageRequestManager.getInstance();
             // Add initializeRequest and endRequest
             prm.add_initializeRequest(prm_InitializeRequest);
             prm.add_endRequest(prm_EndRequest);
            
             // Called when async postback begins
             function prm_InitializeRequest(sender, args) {
                 // get the divImage and set it to visible
                 var panelProg = $get('divImage');                
                 panelProg.style.display = '';
                 // reset label text
                 var lbl = $get('<%= this.lblText.ClientID %>');
                 lbl.innerHTML = '';
 
                 // Disable button that caused a postback
                 $get(args._postBackElement.id).disabled = true;
             }
 
             // Called when async postback ends
             function prm_EndRequest(sender, args) {
                 // get the divImage and hide it again
                 var panelProg = $get('divImage');                
                 panelProg.style.display = 'none';
 
                 // Enable button that caused a postback
                 $get(sender._postBackSettings.sourceElement.id).disabled = false;
             }
         </script>
 
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <asp:Label ID="lblText" runat="server" Text=""></asp:Label>
                <div id="divImage" style="display:none">
                     <asp:Image ID="img1" runat="server" ImageUrl="~/images/progress.gif" />
                     Processing...
                </div>                
                <br />
                <asp:Button ID="btnInvoke" runat="server" Text="Click"
                    onclick="btnInvoke_Click" />
            </ContentTemplate>
        </asp:UpdatePanel>
    </div>
    </form>
</body>
</html>
 
As shown in the code above, we first get a reference to the PageRequestManager and then wire up the initializeRequest and endRequest events to execute, when an async postback begins and ends respectively.
When the user initiates a postback by clicking on the button kept inside the UpdatePanel, we set a delay of 3 seconds. To display progress to the user, we handle the InitializeRequest at the client side and set the divImage to visible. This shows up the .gif image with the progress as shown below. The button that caused the postback is disabled during this event, so in order to prevent users from hitting the button again.
Progress Bar
Note: Remember that you cannot have simultaneous async postbacks using ASP.NET AJAX.
When the async postback completes (in our case when 3 seconds are over), the endRequest event gets fired. The divImage is set to invisible, there by hiding the gif image and the button is enabled again.
Method 2: Using the UpdateProgress control to display progress in an ASP.NET AJAX application
Another very simple option to display progress during an async postback is to use the UpdateProgress control. You can use this control to display status information to the user, while the UpdatePanel updates its content. In the example below, we use the same .gif to display progress while the UpdatePanel is updating its content. For understanding purposes, we have emulated a time consuming operation by setting a delay of 3 seconds by using Thread.Sleep(3000) on the button click.
 C#
    protected void btnInvoke_Click(object sender, EventArgs e)
    {
        System.Threading.Thread.Sleep(3000);
        lblText.Text = "Processing completed";
    }
VB.NET
      Protected Sub btnInvoke_Click(ByVal sender As Object, ByVal e As EventArgs)
            System.Threading.Thread.Sleep(3000)
            lblText.Text = "Processing completed"
      End Sub
 
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="UsingUpdateProgress.aspx.cs" Inherits="_Default" %>
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:ScriptManager ID="ScriptManager1" runat="server">
        </asp:ScriptManager>
        <asp:UpdateProgress ID="updProgress"
        AssociatedUpdatePanelID="UpdatePanel1"
        runat="server">
            <ProgressTemplate>           
            <img alt="progress" src="images/progress.gif"/>
               Processing...           
            </ProgressTemplate>
        </asp:UpdateProgress>
       
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <asp:Label ID="lblText" runat="server" Text=""></asp:Label>
                <br />
                <asp:Button ID="btnInvoke" runat="server" Text="Click"
                    onclick="btnInvoke_Click" />
            </ContentTemplate>
        </asp:UpdatePanel>        
    </div>
    </form>
</body>
</html>
 
In the code shown above, we use the AssociatedUpdatePanelID property of the UpdateProgress control to associate it with an UpdatePanel control. The ProgressTemplate property that can contain HTML, is used to specify the message displayed by an UpdateProgress control. In our case, we are displaying a .gif image progress as shown below
Progress
Method 3: Using UpdatePanelAnimationExtender to display progress in an ASP.NET AJAX application
The UpdatePanelAnimation control can also be used to visually display progress to the users while the UpdatePanel is performing some operation. As defined in the ASP.NET AJAX documentation “The UpdatePanelAnimationExtender is a simple extender that allows you to utilize the powerful animation framework with existing pages in an easy, declarative fashion. It is used to play animations both while an UpdatePanel is updating and after it has finished updating”. You can read more about the UpdatePanelAnimationExtender over here. For this sample to work, drag and drop a UpdatePanelAnimationExtender from the AJAX Toolkit on to your page.
<Animations> are declared in the UpdatePanelAnimationExtender to create animation effect. Within the <Animations>, you can define the sequence of effects for the UpdatePanelAnimation. You can even use <ScriptAction> definitions to fine-tune and customize the animation.
In this example, we will show how to display an image progress bar using the <ScriptAction> definition of the UpdatePanelAnimationExtender. In the example given below, we have defined two <ScriptAction>; one for while the UpdatePanel is updating(<OnUpdating>) and one for after the UpdatePanel has finished updating(<OnUpdated>).
The two <ScriptAction> definition tags call two JavaScript methods respectively that are responsible for displaying and hiding the image progress bar while the UpdatePanel performs an update on the control. As shown in the previous methods, we have emulated a time consuming operation by setting a delay of 3 seconds by using Thread.Sleep(3000) on the button click. You can replace this code with any time consuming operation, like fetching records from a remote database or performing any similar resource intensive operation. The technique of hiding and showing the image also remains the same as we had discussed in Method 1. The entire source code and mark up is as shown below:

            </OnUpdated>
        </Animations>
        </cc1:UpdatePanelAnimationExtender>       
    </div>
    </form>
</body>
</html>
 
C#
    protected void btnInvoke_Click(object sender, EventArgs e)
    {
        System.Threading.Thread.Sleep(3000);
        lblText.Text = "Processing completed";
    }
VB.NET
      Protected Sub btnInvoke_Click(ByVal sender As Object, ByVal e As EventArgs)
            System.Threading.Thread.Sleep(3000)
            lblText.Text = "Processing completed"
      End Sub
 
The progress will look similar to the ones shown in the other methods
progress
Well those were the three different methods of displaying progress to the user while the UpdatePanel updates its contents. The entire source code of this article can be downloaded from here (pwd:dotnetcurry123#). I hope this article was useful and I thank you for viewing it. 
Give a +1 to this article if you think it was well written. Thanks!

Very nice article. But, I am working on Master page, and there are 2 usercontrols in the Masterpage which uses 2 different update panels in each of them and if I click Retrieve button for one user control, I am getting the loading image for both of the usercontrols. Is there any other way to work with this kind of problem. Please update me..

very insightfull post, but which method is the
A) Best in terms of speed, responsiveness and load on server
B) Do you recommend in terms of code maintainability and good development practice

Me thinks A, the pure JScript options is the most lightweight, It will however be a nigthmare to maintain. Your thoughts?

Regarding the Copy-Scape notice on this page, is it OK print a PDF of this document? Please advise. Thank you. -- Mark Kamoski

Nice article. I really appreciate it. The only suggestion that I will make is to somehow tweak the page layout a bit because the embedeed VS.NET ad-based video wreaks havoc on the page, bouncing around, etc, and the page in general does not print to PDF very well due to ads. Aside from that, it is great. Thank you. -- Mark Kamoski

Thanigainathan - Yes.

sa - Go ahead. Do you face issues?

Stephen - If it was speed and responsiveness, I would rather focus on the task that is being performed in the UpdatePanel and find means to speedup. The difference between the 3 approaches in terms of speed should not be much, although I have observed that the animation extender is a little slower than the other two.

Watch out for one of my forthcoming articles where I show a similar approach using jQuery!

Mark: Thanks. Yes you can print the article. Can you send me a screenshot using the 'Contact' page where the VS.NET ad spoils the page view. Also please mention the browser and version you are using.

Also, we will be providing the Print option very soon on the site. It's currently being tested.

Unfortunately this is only a Binary Progress State, its eater working or done...

What would be cool is to have an intermediate indicators for ex: 10%, 20%, 30%, etc...  

protected void btnInvoke_Click(object sender, EventArgs e)
    {
        System.Threading.Thread.Sleep(3000);
        lblText.Text = "10%";

        System.Threading.Thread.Sleep(3000);
        lblText.Text = "20%";
    }

Only way i got that to work was to set Value into Application Variable and Check and Update value from Client Side every 2 sec,
if any one has a better solution please share...

Hi. Love the code it works great but when i have 2 different update panels on a page and i click either button both images show at the same time. Is their away around this. All the best AnnieX.

        function onUpdating1() {
            var panelProg1 = $get('divImage1'); //get the divImage
            panelProg1.style.display = ''; //set it to visible

            var panelProg1 = $get('divImage1'); //get the divImage
            panelProg1.style.display = 'none'; //set it to invisible

        ///btnAddZone1: These two functions are used when the btnAddZone1 button is clicked
        function onUpdating2() {

I get this error for the first two options... what am I missing?

Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed.

When I click on the link to download the source code for these examples I am taken to all of your examples.  I cannot find the source code for these examples. Would you please supply it?
Thanks,
Logan
