AJAX :: IE 8 Causes Page To Render Slow?

Apr 21, 2010

I have an application that runs perfectly fine and fast in IE 7. There are certain pages in the application that use the AlwaysVisibleExtender control.

However, when I run the app in IE 8, the same exact pages seem to lock up for roughly 5 seconds before they render completely. What's weird is that the page shows all the contents except for the alwaysvisibleextender and relating panel. Then after the 5 seconds the panel shows. During that 5 seconds the page cannot be navigated or scrolled. This is not really acceptable.

Chart Control Too Slow Or Doesn't Render

Jan 20, 2010

I have a web page rendering two pie charts using the ASP.NET 3.5 chart controls. On my dev server (IIS 5.1) the charts load well. On the QA server, the charts load pretty slowly and sometimes one or both of them doesn't even load. I am loading the charts using the codebehind tag. Is there anything else that could be done to make these charts run faster? Note: I was previously using dotNETCHARTING and never had any issues with it. Nothing else has changed except for the charting engine.

AJAX :: How To Keep Value After Page Render Again

May 8, 2010

in my updatePanle have 5 controls

RadioButton1 TextBox1 TextBox2
RadioButton2 TextBox3

I use javascript to change TextBoxes's Status each time RadioButton.onClick

now I want to force controls in UpdatePanel render again eachtime RadioButton clicked..

I add _doPostback to my javascript..

the result is not ok... because I lost the value after page render again

for example,user fill in these value to controls

RadioButton1 (Checked) TextBox1 (Text= 90 , Style = "AA") TextBox2 (Text=30 style="BB")
RadioButton2 TextBox3

then user change controls like this

RadioButton1 TextBox1 (Text= 90) TextBox2 (Text=30)

RadioButton2 (Checked) TextBox3

I want to force controls render again but keep the value and style .

User Controls Is Very Slow In Loading Page (AJAX)

Aug 23, 2010

I have an .aspx page with multiple .ascx (User Controls on it). One of the User controls is very slow in loading (calls a very slow webservice for the data.). Now, my question is how to render all the controls on the page (so the User can view those) and have a rotating icon for this control (slow one) (till it loads). I know, I need to bring AJAX into picture, but any clarification on that would help as I will be new to AJAX programming.

Web Form Render Engine Outputs A Control Tree / Looking For Info On Render Logic.

Feb 12, 2011

I've been watching a video on Scott Hanselmnn teaching MVC 2 tricks/tips. He mentions how MVC 2 by default uses ASP.NET Web Forms view engine to render the output of the views; he mentions that the web forms view engine is a little slower than it could be for MVC 2 since it generates a control tree and then outputs the HTML to the page (I hope I said that right).

I was wondering what he meant by web forms generating a code tree before outputting the HTML to the page. Does anyone have insight on the view engine of Web forms and the steps of the rendering process works for ASP.NET and MVC2?

Ajax Request Times Out (or Is Really Slow)

Nov 15, 2010

My basic structure is that I have a table on a page, which I want to reload without refreshing the entire page. So on clicking a button on the page it fires of this:

function RefreshMissionsAjax() {
//fade out the old table.
//request the new value from the page (calls the GetIncompleteMissions() method in the MissionViewer.aspx.cs page)
type: "POST",
url: "MissionViewer.aspx/GetIncompleteMissions",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
error: function (xhr, ajaxOptions, thrownError) {
$(clientID('MissionsDisplay')).html('An error occured while trying to refresh the page data.');
And I have in the code bedind of an aspx page:
public static string GetIncompleteMissions()
return GetHTMLTable();

This method just grabs some data, and creates a html table - nothing too fancy. When the returned table is small (a dozen rows or less) then it works like a charm. But when it gets larger, it takes a long long time. At 100 rows it can take 5 minutes to render the table. At 1000 rows I have left it for 30 minutes and nothing will happen after the fadeout. (NB - it loads fairly quickly on the pageload, before the ajax refresh is used, so it is not the actual server side creation of the table thats the problem).

This is my first real attempt at doing something like this, so I dont know if this is the best way to do it - it was just something i pieced together that worked great when i was testing with small datasets. Now, not so much.

AJAX :: Using Pages Extremely Slow Load?

Feb 18, 2010

So i'm new to AJAX and just installed the AJAX toolkit.

When i have tried to used any of the object there my page are really slow, it like the server is forever to compile the site and when that is done the browser shows it in a flash.

You can see here :


This is not a problem when using only ASP.NET.

When i debug in VS2008 i can see that is looking for some random files when compiling like C:AjaxBuildAjaxServerAjaxControlToolkitToolkitScriptManagerToolkitScriptManager.cs and alot of other stuff, it goes through alot of setting there and i think that is the hold up, why it's so slow.

I have Sp1 installed, running Windows 7 64bit.

These pages are very small and standard. I basicly drag a toolkitscriptmanager, htmleditor, textbox and two buttons to the form. There isnt more.

This is the code for the first page :


The host has AJAX support and has installed SP1 for .NET.

AJAX :: ComboBox Load Slow On Postback?

Feb 23, 2011

I have a situation where I need to have close to 30 drop down lists on one form. The user also wants the autocomplete functionality. I decided to use the ASP.NET AJAX control. So that the page will load faster I hide them until they are needed. But, as more and more become visible the postback time is getting longer and longer.

I know this can be fixed, but I'm not sure how. Can anyone give me any advice, point me to some articles? Do you have a suggestion for another method of doing what I need? Maybe, I shouldn't even be using ComboBoxes for this?

Performance - Webforms W/ AJAX Slow Rendering?

Mar 1, 2010

I have a Webforms, AJAX-enabled web page which, when rendering large amounts of data, is extremely slow to load in IE (we're married to IE - no other browser options). In an attempt to determine the source of the slowness, I viewed the HTML source (about 2.5 MB) and copied all of it (except for the Ajax JavaScript calls) to a blank .html file. IE renders this file MUCH faster than when the rendering happens through .Net. This seems to indicate that the AJAX JavaScript is slowing down the display of the page. Does this sound plausible? Any recommendations on improving performance here?

I've already eliminated as many UpdatePanel controls as I can from the page, but it doesn't seem to help with render time.Update... In the HTML source, I noticed that at the bottom of the screen, a call to WebForm_InitCallback() appears. When I executed this call directly through javascript:alert(WebForm_InitCallback());, the CPU spikes for 12 seconds before it completes! This call is here because I implemented ICallbackEventHandler to try to accomplish some traditional-style AJAX handling. Looking at WebResource.axd, that WebForm_InitCallback() method iterates through the entire form and attaches some kind of events to EVERY SINGLE textbox, checkbox, radiobutton, etc. So I guess I really need to abandon ScriptManager and UpdatePanel altogether here.

The problem is the page loading process is slow, very slow. I am thinking one of the possible cause is jquery itself.

Slow Initial Page Load

Jan 22, 2010

I'm writing a simple web site using codebehind for each page, however using the "codefile" directive, not "codebehind" as such, because I'm not precompiling. I'm just using a text editor to edit the aspx and codebehind files. Problem is, every time I make a change to the code or the aspx file, and refresh the page in the browser, it takes a 2 or 3 seconds to come up the first time, like it's doing an on-demand initial compile. I assume that's what it's doing, as after the initial load, the page refreshes without any delay at all.

This behaviour is quite frustrating when making small changes to the html or code. I'm coming from classic ASP, where you could edit-refresh-edit-refresh etc. all day without your "stride" being broken by waiting for a "compile", you know? So I'd love to know if there's a setting which prevents this initial delay. When I want to deploy, I can do a compile or something, but while making lots of small edits, I just need the page to run without that initial delay.

Slow Of First Page - Running On Windows / IIS

Mar 16, 2011

I'm more into the LAMP stack, but I've been asked to work on a site that is running Windows and IIS 2008. I'm a beginner with IIS, so please be patient with me on this, and please ask me to provide more information if that is needed to determine. I read the answer here (Slow first page load on asp.net site), but it seems like if I go to the site with one browser it takes long to load the first page, then fast on all other pages, then if I open up another browser, it's the same thing, so it's not something that is saved on the server, but per session? Is there a way to have the application running at all times? Right now it is taking 12 to 15 seconds for the first page to load. I have access to the WebControlCenter and FTP.

Web Forms :: Page Load Very Slow?

Sep 21, 2010

I've developed a web page Client.aspx that is used for editing a client. This application has been deployed and I made sure that debug='false'.Upon selecting a client from the dropdownlist, his/her information is retrieved for editing. This retrieving process is very slow( about 9 seconds).Except this DropDownList, all the other controls on this page are within the Update Panel. There are 2-3 other Update Panels within the main Update Panel.

When a client is selected from the DropDownList, the Client_ID (DataValueField) is used to retrive the informationSELECT * FROM CLIENTS WHERE Client_ID=1576
This method returns a dataset.In the calling method I'm assigning these values to the respective fields.Some JavaScript is used for validating Phone#.I also have a RadioButtonList on this page. When one of the ListItem is selected I need to disable a TextBox. Even this process is taking much time than expected.
