IE9 Beta and UpdatePanel

Posted By:      Posted Date: September 16, 2010    Points: 0   Category :ASP.Net
Has anyone else problems with IE9 Beta and UpdatePanel? When I make a postback with a UpdatePanel i get many JavaScript Errors like this "Microsoft JScript runtime error: Invalid set operation on read-only property". It works fine in IE 7/8, Chrome, Firefox and Opera.I use the ScriptManager from AjaxControlToolKit (Latest Version).

ASP.NET 4 and Visual Studio 2010 Web Development Beta 2 Overview

Many exciting changes for ASP.NET are coming in the .NET Framework version 4. This document gives an overview of many of the new features that are included in the Beta 2 release of the .NET Framework 4 and of Visual Studio 2010.

Visual Studio 2010 Beta 2

This is a big deal. This isn't ".NET 3.6" - there are a lot of improvements of .NET 4, and it's not just "pile on a bunch of features so you get overwhelmed." I've been working with and talking to many of the teams involved and even though it's a cheesy thing to say, this is a really customer-focused release.

ASP 4 - Whirlwind Tour around .NET 4 (and Visual Studio 2010) Beta 1

There's a lot of stuff that's new and added in .NET 4, but not in that "overwhelming-I-need-to-relearn-everything" way. More in that, "oh, this is way easier/simpler now" way. Like, moving data around with ADO.NET DataServices is easy, binding with client templates is easy, there's F# if you need it, the "dynamic" keyword if you need it, Silverlight's already installed, oh, and the parallel stuff will freak you out, but in a good way.

UpdatePanel is not a known element - message when upgrading to 1.0 ajax


It worked on one of my old pages.  I change the web.config, renamed all the <asp.

On some aspx page it doesn't recognize the updatepanel.  It only does on one page.  If I create a new aspx page with a different name - then it works.

Should I just create a new web project ajax - then copy all my code into there?  Or is there a way to get those old pages to recognize the new ajax controls?

.NET Migration Case Study: Using ASP.NET to Build the beta.visualstudio.net Web Site


When the Web site used to collect customer feedback about the Visual Studio .NET beta needed an update, the Visual Studio team saw a good opportunity to implement, deploy, and showcase a real-world site using .NET technologies. This article covers the migration of the Web site, beta.visualstudio.net, from components written in Visual Basic 6.0 and ASP hosted on Microsoft Internet Information Services (IIS) 5.0 to ASP.NET and the .NET Framework. The choices of technologies to be incorporated, along with issues such as validation, security, and authentication, are all discussed. Both existing components and the new components written in JScript and ASP.NET that were used to migrate the site are also explained.

How do you insert a google map into an ajax updatepanel?


I have built a site that I am using google maps on.  The default page has a google map with info windows containing links and all works great... until a user clicks on the link in the info window.  Doing so takes them to a community page that I have built.  On this community page, I have an ajax update panel that has 2 panels nested inside of it with the visibility set for one to be on and the other off.  The default panel shows community photos, and the second panel I want to show the google map and common directions to the community.  In testing, my buttons to switch the visibility of the panels works great as it should without postback, but when I try to add the map to its panel, it does not show up.  I am new to ajax as well as google maps and I'm not sure why the same code would work fine on my default page but not the community page.  The only obvious thing I can assume is because the community page map is in an update panel.  

How do you insert a google map into and ajax updatepanel and have it work correctly?  Many thanks in advance. 

ModalPopup/UpdatePanel from codebehind, inconsistent behavior onClick


First post bear with me please:

I have a simple form with a list of linkbuttons, each fires the same onclick event which sets an indicator image.  I have a dummy button with style="display:none" which I have set as the TargetControlID of the modal.

onClick event from the imagebutton, the modal is shown via modal.Show().  The cancel button inside the modalpopup fires an event which turns off the indicator image and hides the modal via modal.Hide(). 

The events fire perfectly, it's very simple!  Although after doing some testing I noticed the modalpopup is not presented after the 6-10th cycle of clicking the open event, then clicking cancel.  The grey background appears but it is behind the main panel and the modal is either presented behind this or is just simply not displaying. 

I spent hours researching various methods, implemented the CancelControlID to see if it was somehow tied to my call of modal.Hide() that fails.

This occurs with an updatepanel only.  The behaviour is much cleaner this way, so I would hope to be able to implement this.  I have basically eliminated everything but these two events!  Please help

UpdateProgress with a dummy updatepanel not working


I have a Submit button and some functionality like updating DB and fetching next page in the button click event. This process takes a long time and I want to display a message saying "Progress...." right after clicking the botton. I want to do the same in 20 other pages. So, best way to do it wd be to put the modalpopup MPE or an Updateprogress in a usercontrol or in master page. I first tried putting both of these on the page itself to test and see and neither worked.

I tried using Update progress control with a dummy updatepanel and giving the Submit button as Asyntrigger to the dummy updatepanel. I have also tried using MPE but it didnt work either. Below is an example of what i did..

<asp:UpdatePanel ID="UpdatePanel1" runat=server><contenttemplate><triggers><asyntrigger ID= "Submit"> /> /> />

<asp:updateprogress ID="Progress1" unat=server AssociatedUpdatePanelID="UpdatePanel1"><Progresstemplate>Progress.... />/>

<asp:button ID= "Submit" runat=server >

I have nothing for updateprogress in code behind. Am i missing or doing somethign wrong here? Any help would be appreciated.

UpdatePanel in a Webpart


I'm exploring the usage of UpdatePanels in WebParts for MOSS 2007. The code I have so far for adding a test update panel is this:

                LinkButton goButton;
                goButton = new LinkButton();
                goButton.ID = "butGo";
                goButton.Text = "Go";
                goButton.Command += new CommandEventHandler(goButton_Command);
                goButton.Click += new EventHandler(goButton_Click);

file upload in Create User Wizard Created User event with UpdatePanel Tag wont work?



In my Create User Wizard1 Created User Wizard Event, I am collecting extra information from text boxes and allowing

the user to uplad a file.



I have put the Submit button within an Update Panel Tag but since I have done this it does not work.

Is there a way round it. In this situation would you use a trigger.?

Total newbie question: Calling jQuery in an UpdatePanel?



Please forgive this ignorant question - I've used ASP.NET AJAX a good deal but I'm new to jQuery.  Specifically, is it possible to call or create jQuery events on the fly via an UpdatePanel?  For example, calling a jQuery modal or animating a Label (or <div> contained Literal), etc.

If anyone has any advice or could point me to some easy tutorials on mixing ASP.NET AJAX and jQuery, I'd greatly appreciate it. 



V1.1 to Beta 2 - Namespaces Not Recognized


We are attempting to test out a website written in VS2003/.Net 1.1 in VS2005 Beta 2/.Net 2.0.  Our main problem at this point is that certain classes are not being recognized when they are referenced in other files not in the same directory as the class file.


A Framework.cs file under \Applications is inherited by several other webpages. It resides under the namespace Company.WebSite.Applications.

Another class, SearchHistories, is in \Applications\CrackHistory directory. The namespace of SearchHistories class is Company.WebSite.Applications.CrackHistory. SearchHistories inherits Framework.  Under .NET1.1, there was no problem with this. However, in VS2003, a compile error states "The type or namespace name 'Framework' could not be found (are you missing a using directive or an assembly reference?) C:\WEB\Applications\CrackHistory\SearchHistories.aspx.cs".

The immediate solution is to copy the Framework.cs file from the Applications directory and copy it into the Applications\CrackHistory directory. Then the error goes away. What is up with that?

Cancelling UpdatePanel progress


I have an UpdatePanel that consists of a button and a GridView. The UpdateProgress as shown consists of an image and a "cancel progress" button. The style on the image helps in graying out the controls on the page but still letting the user view those (due to the opacity settings). What is the best way to implement cancelling the progress of loading data into the GridView by clicking the cancel button.

<asp:ScriptManager ID="sm1" runat="server" />
        <asp:UpdateProgress AssociatedUpdatePanelID="upCheckBoxes" ID="upr1" runat="server">
                <div id="container">
                    <img src="images/loading.gif" id="loadingimg" />
	<asp:UpdatePanel ID="upCheckBoxes" runat="server" UpdateMode="Conditional">
	<asp:AsyncPostBackTrigger ControlID="btnSubmit" EventName="Click" /> 
		<script type="text/javascript">   
			Sys.Application.add_load(BindEvents);     //Doing some jquery stuff here
