Progress Area resets when complete Issue

[Paul J]

I'm using a Progress Area Control to monitor the progess of some code (actually just calling System.Threading.Thread.Sleep(4000)) for right now to simulate code doing stuff. Anyway, it runs fine until it finishes, at which point both the progress bar and the OperationText seem to "reset" back to the first thing I set it to.

For example.

I initially set the PrimaryPercent to 0 and the CurrentOperationText to:  "Initialization started...". the last thing I do is set the PrimaryPercent to 100 and the CurrentOperationText to:  "Initialization Complete...".  It shows this on screen but then seems to reset the PrimaryPercent to 0 and the CurrentOperationText back to:  "Initialization started..." before the page response is finished.

Any idea why? I'm setting the progressContext.OperationComplete = True before the final update. Here's my full code:

<asp:button runat="server" ID="btnInitialize" Text="Initialize" CssClass="button" />

<telerik:RadProgressManager ID="RadProgressManager1" runat="server" />
    <telerik:RadProgressArea ID="rpaInit" Width="100%" ProgressIndicators="TotalProgressBar, CurrentFileName" runat="server" Skin="GCSD" EnableEmbeddedSkins="false">
      <ProgressTemplate>
        <ul class="ruProgress" runat="server">
                <li class="ruProgressHeader" runat="server"><span id="ProgressAreaHeader" runat="server"></span></li>
                <li class="ruFilePortion" runat="server"><div id="PrimaryProgressBarOuterDiv" class="ruBar" runat="server"><div id="PrimaryProgressBarInnerDiv" runat="server"></div></div></li>
                <li class="ruCurrentFile width100Percent" runat="server"><span class="lblCurrentOperationTitle">Status:</span><asp:label runat="server" id="CurrentOperation" class="lblCurrentOperation" /></li>
            </ul>
    </ProgressTemplate>

Private Sub UpdateProgressMessage(ByVal progressContext As Telerik.Web.UI.RadProgressContext, ByVal strMessage As String, ByVal intPercentComplete As Integer)
        Dim strScript As String
        Dim writer As New StringWriter

        progressContext.PrimaryPercent = intPercentComplete
        progressContext.CurrentOperationText = String.Format("{0}", strMessage)

        progressContext.Serialize(writer)

        strScript = String.Format("{1};Sys.Application.add_load(function(){{$find(""{0}"").update(rawProgressData);}});", rpaInit.ClientID, writer.GetStringBuilder().ToString())

        ClientScript.RegisterStartupScript(Me.[GetType](), "", strScript, True)


    End Sub
    Private Sub btnInitialize_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnInitialize.Click
        Dim progressContext As RadProgressContext = RadProgressContext.Current

        rpaInit.DisplayCancelButton = False

        UpdateProgressMessage(progressContext, "Initialization started...", 0)

        System.Threading.Thread.Sleep(2000) 'delay it a couple seconds

        UpdateProgressMessage(progressContext, "Loading Stuff...", 25)

        System.Threading.Thread.Sleep(4000)

        UpdateProgressMessage(progressContext, "Loading More Stuff...", 50)

        System.Threading.Thread.Sleep(5000)

        UpdateProgressMessage(progressContext, "Loading Even More Stuff...", 75)

        System.Threading.Thread.Sleep(5000)

        progressContext.OperationComplete = True

        UpdateProgressMessage(progressContext, "Initialization Complete", 100)

    End Sub

Hi Paul J,

Is your RadProgressManager inside of RadAjaxPanel/UpdatePanel or ajaxified using RadAjaxManager? If so, move it out of the ajax area and try again. Does the issue persist?

Kind regards,

No, it is not inside of any kind of UpdatePanel nor RadAjaxPanel. Nor is it ajaxified using the RadAjaxManager.

Hello Paul J,

I've already answered to you in the support thread, however, I will paste the answer here as well for a community reference. In order to achieve the desired functionality please do the following:

1) Remove the following from your code, you don't need it

progressContext.Serialize(writer)

strScript = String.Format("{1};Sys.Application.add_load(function(){{$find(""{0}"").update(rawProgressData);}});", rpaInit.ClientID, writer.GetStringBuilder().ToString())

ClientScript.RegisterStartupScript(Me.[GetType](), "", strScript, True)

2) Place the RadProgressManager and the the Initialize button inside a RadAjaxPanel while keeping the RadProgressArea outside of it.

All the best,

Thanks for the info. I did as you suggested, but as soon as I add in the RadAjaxPanel control, it gives me a 'Sys' is undefined error when the page loads. If I take it away, then the page loads fine.  I've read through the telerik blog post about the generic 'Sys' is undefined, but still could not resolve my issue. I had already had many other telerik controls on the page and they were fine, but again, once adding the specific RadAjaxPanel control, it throws that error.

any ideas?

Hello Paul J,

You can try with UpdatePanel as well. Does the issue persist? If so, please attach here your aspx code so that we can take a look.

No need, I was able to isolate my issue.

Your attached sample project greatly helped me to isolate the code line that was giving me the errors. I had a simple line in the aspx file that pulls a variable value from the appSettings section of the web.config file, and this was causing these errors after I had added the radAajaxPanel to the page. I honestly am not sure why the two conflict and cause these errors, but I easily adjusted to set a literal control's value to the webconfig's variable in the codebehind.

Thanks again.
