I've tried removing the update panels but it is still slow
View 3 RepliesI have a problem with the performance of the web site-application . The major problem is when i hit the site from a long distance remote pc all server side events responces are too slow espesially the gridview (paging) , the point is when i used ajax update panel of asp.net it was more slower .
View 6 RepliesI have created a website with asp.net 3.5 and c# (using linq to sql). its a basically a project managment system. bt its very slow when u look at its loading time. my dashboard takes a whole lot of time to load.when i look at other sites created by my colleagues it loads much faster than my site. they have developed it using ado.net + Stored procedures. that made me believe that linq to sql is slower than ado.net + SP combination.to improve my site perfomance using linq to sql.
View 4 RepliesI am using the asp.net 3.5. i have development a website using master page, user control, update panel, asp.net ajax such as loading box and message box etc. when i testing the site in my local, it show with the normal speed. but after i upload the website into the live server, the loading box and message box is slow loading.if there is a popup of messagebox, it is slower and when i click the ok button on the message box. it seem close in very slow and have a duplicate box come out. i have no idea on it. why it is so slow when uploaded to the server?
View 1 Replies have a website with MasterPages, on load master page has many database roundtrips and logics implemented.Now, if move to one page to another, the MasterPage get reloaded and all the above mentioned procedures processed again, which again takes a lot of time and as a result my website's response is very slow.For eaxmple, once the default page is loaded, all the child pages can load within the centent area (in ajax style).
tell me some workaround to optimize the site so that it doesn't this procedures repetitively.
I recently upgraded to Windows 7 Ultimate on my work computer. Before this debugging a website in Visual Web Developer 2008 was really fast - the page loaded up like a normal website would.
Since I've upgraded to Windows 7 the page loads like normal but gets stuck for about 30 seconds at the end of the load - this is slowing me down as I normally need to use the FireBug tool as soon as the page has loaded.
I have a really weird problem that I've been investigating for at least one week now. I deliver a website hosting both ASP classic and .NET 3.5 content in IIS6 on a Windows 2003 server environment with MySQL db backend. The solution has been installed on several servers (some hosted in WMWare) with no problems. On one specific server, also hosted in WMWare, the user experience great performance issues on the website. The problems are most seen when using database resources and is not limited to either .net or asp classic, but I am still not sure that the problem is only related to database calls.
Following components are involved:
IIS6 .NET FW 3.5 MyODBC 3.51 / 5.1 MySQL 4.x
Code executed on the server using all resources above runs smoothly when the IIS is not involved. The website shows times up to 2 minutes to execute code that takes 2 seconds outside the IIS. The exact same code is executed. Using profiling tools, I've seen that the great loss comes within calls to unmanaged code, for example when System.Data.ODBC namespace to calls into myodbc.dll.
The tricky part is: If at least one console user is logged in to the server, the performace problems are not seen anymore. When the user logs out, the problem appears again.I have tried to reinstall all components above, tried different versions of MyODBC, tried different website authentication methods, tried to run website under administrator privilegies, installed various MS KB's with no success.
speed Performane i create a web site but it very slow run i use tree view and grid view but i do it run very fast
View 1 RepliesMy 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.
$(clientID('MissionsDisplay')).fadeOut(500);
//request the new value from the page (calls the GetIncompleteMissions() method in the MissionViewer.aspx.cs page)
$.ajax({
type: "POST",
url: "MissionViewer.aspx/GetIncompleteMissions",
data: "{}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
$(clientID('MissionsDisplay')).html(msg.d);
$(clientID('MissionsDisplay')).fadeIn(500);
},
error: function (xhr, ajaxOptions, thrownError) {
$(clientID('MissionsDisplay')).html('An error occured while trying to refresh the page data.');
$(clientID('MissionsDisplay')).fadeIn(500);
}
});
}
And I have in the code bedind of an aspx page:
[WebMethod]
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.
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.
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.

And here is my aspx code:

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.
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?
my page contain a dropdownlist which binding many list of data with no categories. While refresh in one update panel is very slow.
View 4 RepliesI 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.
Why the ajax control is working slow when i upload to the server? such as the custom validator is slow response in the server, the modal popup box or loading is slow to response or close up after click the ok button. It work fast in the local server.
View 2 RepliesI 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.
View 4 RepliesI made a login system, when the user presses the login button a pop up panel using ajax appears. The textboxes and other features are in a Web User Control.
The problem is that when writing information in the textboxes in IE or pressing the cancel button it is very slow compared to other browsers. I have the latest version of Ajax.
I'm trying to implement AJAX within an existing application and it seems to be running slow.
I have 3 datallist that all have checkboxs. I have buttons that all users to check all checkbox for a specific datalist. I have an update panel around each datalist. When I check and uncheck it seems to be really slow. I also have 3 textboxes and 4
buttons within my update panel.
When I user uses this site it hides and shows different panels and that seems to be really slow when the users press a button. There is no database stuff happening when the slowness occurs.
I was wondering if anyone could tell me why any .aspx page that I drop an Ajax HTML editor on will then become painfully slow to load and update.And more importantly is there anything that can be done about it to speed it up?I am using VS2010 and targeting ASP.Net 4.0 web application and I am using the AjaxControlToolkit version 4.1.40412.2.

View 4 RepliesI have a Gridview containing 10 columns and anywhere from 10 to 40 rows and each cell contains either dropdown or input boxes.I also have a calendar control that changes the data displayed in the gridview.Right now I have an outer update panel around the entire gridview and then I have inner update panels around each control, so potentially 400 update panels depending on the amount of rows for each day.The individual control updates happen fairly quickly if I for example change a dropdown etc, but when I change the day and the entire gridview has to refresh it is painfully slow.On average 30-50% of the cells will be manipulated between change of date. What is best practise? Right now it is to slow.
View 2 RepliesWhenever I use ASP.NET AJAX it's calling Resource.asx files many times and it's affecting site performance. How can we avoid that?
View 3 RepliesI have problems with optimizing AJAX Control Toolkit. The specific problem is that 4800 records take about 30 seconds to bind in Internet Explorer (only 2 seconds in Opera & Firefox). I've tried anything, but I still can't improve the load time in IE.I've already enabled compression and caching, I'm using ToolkitScriptManager instead of ScriptManager. I've tried setting LoadScriptsBeforeUI and EnablePartialRendering to false, but it still doesn't help.
This is the query I use for binding.
