[RESOLVED] UpdateProgress not working under Updatepanel control.?

Dear All,

In my aspx page I have UploadFile, Button and a Gridview. I have embedded all controls in Updatepanel control but upon selecting file in UploadFile control, Upon click of the button UpdateProgress text message does not work whereas without using Updatepanel it works very fine.

What could be the reason? and solution for this.

see the code below:

Code:

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" >
                        <ContentTemplate>
                            <table border="0" cellpadding="0" cellspacing="0" style="width: 100&#37;;">

Hey,

Can you go back and edit your post and put [CODE][/CODE] tags around your code? It would make it so much easier to read!!

Normally when you add any PostBackTrigger to your updatepanel the updateprogress won't display. You have to display it explicitly.Add a javascript to show the update progress.

1.Add one ProgressLabel to your form(lblProgress).
2.If you want to validation, you can call in the Scriptvalidation string.
3.In the code behind you have add one javascript event for this

Code:

---

btnSave.Attributes.Add("OnClick", String.Format("{1};this.disabled = true;document.getElementById('lblProgress').innerHTML='Please wait as the vehicle is being moved...'; {0};", ClientScript.GetPostBackEventReference(btnSave, Nothing), ScriptValidation))

---

The above function will disble the button which caused the postback as long as the process is happening.
And the progress is shown. If you want to do some validation you could add in ScriptValidation string

And in the Page Design view add this javascript

Code:

---

<script language="javascript" type="text/javascript">
            function displaywaitmsg()
            {
              var objProgress=document.getElementById("lblProgress");
              if (objProgress != null && objProgress != undefined)
              {
                objProgress.innerHTML="Loading...";
              }
            }
</script>

File Upload controls don't work straight away in UpdatePanels as they're a bit more complicated than simple partial-postbacks. Have a look here:

You could also use the AsyncFileUpload control which is part of the latest ASP.NET AJAX build:
