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?

I 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.

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 main.aspx page, it contains several tabcontainers. In each tab container, there is an iframe with the src="myPage.aspx".
In the myPage.aspx, I have added two comboboxes. The buttons of the comboboxes do now show at all until a postback on the myPage.aspx.

I have a MVC view using the following VM.
[Code]....
Currently the page load slow. I am thinking of using JQuery load and render List<A> and List<B> separately and asynchronously. Can I still use MVVM pattern? Or I had to create to controller methods returning List<A> and List<B> separately?]

I have the following items bound to my combobox:
Value: 1, Text: SNS
Value: 2, Text: ING
Value: 3, Text: ING
Choosing value 1 results in a SelectedValue of 1
Choosing value 2 results in a SelectedValue of 2
Choosing value 3 results in a SelectedValue of 2
does the combobox has as a disadvantage that the Text has to be unique?

I'm try to add a combobox to my form which i have done and populate it with the infomation i need but i want to stop the user from being able to edit the first 5 character in the textbox part of the combo box( 1 is this possible 2 am i going about it in the right way).
I have 3 columns fro a db to enter ips ie 123.456.7.89 at the start if each number i want (SE1)(SE2)(SE3) which i can do at the momment . So I get in the combobox list 3 items with (SE1)123.456.7.89 OR just (SE1) depending of i a result is returned from the DB. However i don't want the user to be able to edit out the (SE?) part of the sting in the textbox. When editing i've tried used the text change event to try and capture the change and make sure the string.length > 5 , but the event does not fire also when i leave the combobox it it adds to the combox list. If I refersh it goes back to how it should be with only the 3 items.

In my base page, I have a dropdownlist control which loads different usercontrols on selectedindexchanged event.
While loading these usercontrols, my page postbacks all the page. I used updatepanel but again same problem.
Is there any way to load controls without postback?
Here is my code:

I have a dynamically generated image placed inside an update panel. The image is generated with the Generated Image control (see here for more:
[URL]. This is basically a specialised httphandler linked to a normal asp:image, where the image src is generated dynamically. In my case, I use some GDI+ to dynamically generate the image, based on values from a database query.
The problem I have is that the image does not update when the update panel updates. The image does, however, update if I manually reload/refresh the page (i.e., hit F5). Why is is that some code fires during an update panel update, and not other code? And, more importantly, what can I do to make sure the image generation code does fire during the updatepanel update?

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.

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.

Every now and then (always after a long period of idle-time, e.g. overnight) when I access a site built using asp.net - it takes around 15 seconds to load the page (15 seconds before I see any progress whatsoever, then the page comes up fast).Further pages on that site, or refreshes, are quick as usual - they are also fast on other machines, only the first one seems to take the 'hit'.
Page tracing never through anything up (whole cycle was a fraction of a second) So my question is where else should I be looking? Perhaps IIS? Or could it still be my asp.net app and I'm just looking in the wrong place (the trace) for clues?As I don't have much control over the IIS server, anything I can check through asp.net would be more helpful, before I go ask that particular admin.

The first time that my page loads (this is after it has been deployed), it is terribly slow.
My guess is that it is still compiling dynamically, and not precompiling.When I publish through VS2008 I have "Allow this precompiled site to be updatable" unchecked and "Use fixed naming and single page assemblies" checked.Could I be missing something in my web.config file?
I can post the URL of the site if you would like to view it, but it takes 10+ seconds to load upon first visiting, and then less than 1 second to navigate the site.

I have a simple web application that loads very slow the very first time after i deploy it. I am using ASP.NET 3.5 SP1 / VS 2008 / Linq / Web forms to load the default.aspx home page. It is a very light page with nothing too fancy.Now to debug this load issue, I logged all the events in the global file and got the following log text:
2010-04-10 11:58:38,083 - Application_Start
2010-04-10 11:58:38,111 - Application_BeginRequest
2010-04-10 11:58:38,117 - Application_AuthenticateRequest
2010-04-10 11:58:52,321 - Session_Start
2010-04-10 11:58:52,454 - Page_Load
2010-04-10 11:58:53,951 - End Page_load
2010-04-10 11:58:53,981 - Application_EndRequest
Now my question is, between the Application_AuthenticateRequest and Session_Start functions, there is generally around 10 - 15 seconds - which i believe seems to be the problem.The thing, I am unsure why this is slow between these two functions.I am not using any forms authentication.Also, I am not doing anything fancy in the global file besides setting a session variable.

We have an asp.net website running on IIS 6 Windows 2003. When ever we upload a class file to the App_Code folder our whole site goes down temporarily until, what I assume, compilation is complete. Has anyone else experienced this? Any other file we upload it does not do this only our class files.

When we include Javascript files in our aspx files. either we write all the Javascript code in the Head section of aspx or we link to an external Javascript file.
So when the clinet makes a call to that page. Does that mean that all the Javascript will be loaded on the client side?
If that is the case then does not that mean that it will slow down the loading of page as all the Javascript has to be loaded on the client machine?
