Auto Submit UpdatePanel and show UpdateProgress area.

Question

I want to auto submit my form and show the update progress area once it is submitted. I have tired adding 2 fucntions to the page:

window.onload=function(){
     __doPostBack('UpdatePanelId','');
}

and....

window.onload=function(){
     var btn = document.getElementById('buttonID');
     btn.click();
}

The page gets posted back to, but the progress area is not showing up. Any thoughts how I can handle this?

Answer 1

Based on your further comments:

you have an UpdatePanel and SomeUploadControl outside of that panel. You want to show UpdateProgress when you cause a FULL POSTBACK from SomeUploadControl.

If the above assumptions are correct - I'm afraid you can't do what you want. The whole idea behind the UpdateProgress is to work on PARTIAL POSTBACKS.

I'm pretty sure the above is correct, but I might be mistaken.

Edited in light of your comment :)

try:

window.onload=function(){
     __doPostBack('buttonID','');
}

if this doesn't work - give more details on the problem you're trying to solve (why are you trying to cause the postback via javascript), and there might be a better way altogether.

I got it to work!!

Origianlly, I had my script running inside the ScriptManager client script block. I moved it outside of the script manager and added a timeout to the script. Here is what it looks like:

            Dim script As String = "window.onload = function(){" & vbCrLf
            script += "setTimeout('submitPage()',2000);}" & vbCrLf
            script += "function submitPage(){" & vbCrLf
            script += " var btn = document.getElementById('" & Me.btnProcess.ClientID & "');" & vbCrLf
            script += "btn.click();}" & vbCrLf    
                            ClientScript.RegisterClientScriptBlock(Me.Page.GetType, "autosubmit", script, True)
