C# - Update Panel Working Very Slow?
Mar 20, 2011
I'm writing an app in which user can register. While registering the one may choose several options and according to these regiester fields are visible or not and are required or not. I came up with an idea that all fields will be in in the updatePanel and when users changes registration options I would set visibility of these fields on the server side.
It works but incredibly slow and whats more on the FF I have the given error:
The state information is invalid for this page and might be corrupted
3 checkboxes with other fields are in the updatePanel
Each field is in dl tag with runat="server>
I had to do it like that cause for "required" option I simply add css class to this dl (need in in javascript validation. If field should be visible I set visible="false" for given dl and then that field for example FirstName with title and so on isn visible after postback.
Am I doing something wrong ? Why does it take so long (~4 min on localhost) and in firefox it doesnt really work (when I use debug I think that process completes without errors on ff, I dont understand that at all :)
If update Panel is so weak what would be other option to change visibility and adding required class to all dls. Logic is quite complicated and has to make query to DB so simple javascript would be quite tricky.
Oh and I'm using ASP.Net and cant upgrade on this project.

I have, what i think is a very simple updatepanel setup. I have searched and found other similar issues, but they date back to 2008 and 2009. Is the fix provided back then the only known fix now? Is there any other fixes or things.

I know it's not the best practice to do, but unfortunately I created a page with multiple large dropdown lists and have them inside an ajax updatepanel. I found some work arounds using siderite's ajax updatepanel adapter:
http://fastlistadapter.codeplex.com/.
The performance is very good while I am debugging on my machine, but when I publish the site and post it to a win 2003 server the performance drops off almost as bad as when the fix isn't there.
I understand that using a 3rd party fix really isn't supported by most, but is there any obvious reason why debug performance would be much better than published site performance on the same exact code?

I'm new to the world of Update Panels and i'm having a hard time figuring out how to use them properly.
I have a form that has a table(TABLE1)...and inside TABLE1 i am linking to a sql data source....at the bottom of the table i have a 'Add' button.
When the user clicks the add button...a modal popup appears (POPUP1) and inside the POPUP1 the user can click a link that can add a user...when the link button is clicked...a panel within POPUP1 is set to visible = true.
I have one update panel around the whole table and the add button...when i click add and then click the link to add a user....the modal popup disappears.

I have added two update panels to my page. I'm trying to update the first panel but not the second. The second panel contains validation controls which seem to be kicking in no matter what I try.
<asp:ToolkitScriptManager runat="server" ID="ScriptManager" />
<asp:UpdatePanel ID="updatePnl" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:label ID="NoConsignments" runat="server" ForeColor="red" />

I am working on an application where i have got, a content page within a Master Page. I have placed a gridview on the page. This gridview has three fields, one of them is TemplateFied, a BoundFiled and a CommandField, along with paging enabled in the gridview.
In the template field i am creating a dynamic javascript on RowDataBound.
I wanted to place this gridview in Update panel so that it doesnot re-loads when command is clicked or page is changed.
I placed a scriptmanager and an update panel, and placed the grid in it. Now my command field works only once and not more, and same is true for the javascript, it doesnt gets initilized.

I have a problem doing a partial page post back with an update panel within a tab container.
I am adding the control programmatically as follows
[Code]....
The controls are added to the tab container but the button now causes a full page postback. The button_click event is no longer called. Is there something I am missing here.

I have placed this control in an aspx page that contains the UpdatePanel. Everything works fine except Download Link.
I have given a Command on donwload link button and a function is associated with the command to start download.
Below is the code i have implemented -

I am fixing issues in a project where I was not able to figure out a solution for the below problem. There are multiple user controls in Main.aspx page. First one is header.ascx which is added directly in .aspx page. and the others are added dynamically from Page_Init event. Basing on the hyperlink clicked from the menu on the left side of the main page, the respective user control is displayed.
Now, If I try to add script-manager/update panel inside any of the dynamic user controls, the respective user control page throws error. I have noticed that the header.ascx control is using scriptmanager. Is it creating the problem? How to handle this kind of issue?

I have one button on my page. On click of this I need to run four methods parallely in four saperate thead and need to show the progress bar for each method. Also need to update the label controls form those threaded methods.
Also I need to user Update panel of AJAX control tool kit to avoid post back to user.
I have used the read pool for that. When I remove the update panel the code works fine and update four labels but when I put the update panel it is not updating the labels.
