If I have an object I need to store in viewstate, what kinds of things can I do to optimize the size it takes to store the object? Obviously storing the least amount of data will take less space, but aside from that, are there ways to architect the class, properties, attrbutes etc, that will effect how large the serialized output is?
View 3 RepliesI've build a class like this:
[code]....
The values of this class are set at postback by clicking a radiobutton list. Problem however is I don't know how to save this values across multiple postbacks. I thought of using viewstate but I'm not quite sure how to do it with this class.
Maybe I'm missing some important thing here.
Hope someone can point me in the right direction.
i want to do some thing like this in in Class inside(App_code) folder i want to know how to do it with
Correct Syntax :
public static void GetViewStateValue(int StudentID,ViewState MyViewState)
{
if(MyViewState["Name"]!=null)
{
}
}
When I use Viewstate in another cs class file it showing error,.The Name Viewstate does not exist in the current context .
View 5 RepliesNow here is the weird thing. First i am running it locally on the built in vs2008 web server.I load my control in fine, do a postback from a linkbutton, locally on my machine it all works fine, no issue.However when it goes onto my host, it falls over with the message:
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request.Now i also load controls dynamically and use postbacks and things in the admin area of the site...and that works fine, however my front end just keeps failing? See the code behing below:

I have problem getting values from viewstate in GetTopThemes.

when the page is not Posted back, I saved all values in the viewstate.
I have been getting this error a lot lately with some of my users, and I had a couple of concerns with view state and I have read so many articles but I am still lost..
1. I use masterpage on all the pages and I need viewstate for some of the pages but..
There is a page where a user will fill out the information and then submit this data to a cgi server, and it is where I get most of the Client Disconnected errors, what would happen if I disable viewstate when they click on that button?
Now when a user browses from one page to another, does the view state from the previous page get deleted? If not how would I delete it?
Does the master page have its own viewstate? Would I be able to make sure none of items on my master page are using the viewstate?
I have a shopping cart page (Cart.aspx) that has a button that will (sometimes) post to a third party payment gateway, if payment is necessary. The payment gateway will process the payment and then do a silent post to my website (Order.aspx) so I can update the order status.
Order.aspx always throws an invalid viewstate error, even though viewstate is disabled on the page.
What's happening is that Cart.aspx (which has viewstate enabled) posts to the payment gateway, and the gateway will post it back as part of the silent post. Even though Order.aspx has viewstate disabled and validation disabled, it still tries to validate the __viewstate field it's being given.
I know setting EnableViewState=false will disable the rendering of the __viewstate field, but if another page provides the field, shouldn't it still skip validation? I tried calling ViewState.Clear() on the Page_Init event of Order.aspx, but ViewState is apparently empty. how to get around this? I don't want to disable ViewState on Cart.aspx (in some cases it may be necessary), but I can't figure out how to clear it on Order.aspx.
I have the following situation: excel-like application, that is accessible from internet.
2 users access it and I want the moment one user clicks on a cell, the other user to see that. (like in google documents).
My questions are:
Can I do this using standard UpdatePanel, while I keep the bandwidth usage to its minimum (in other words, only information for the current cell is passed, not the whole huge table), or should I implement my own ajax scripts on the page in order to get it optimized.How to do the updating : one way is to have a timer on the page and update it periodacally, the other way is to make a request and keep the connection opened till a change is made (using some heavy timeout, let's say 1 minute). Can you give me clues (like ajax libraries I can use, can I do this with the standard ajax controls in asp.net, ways to implement the live connection)?

That can be optimized?
is it possible it called once at the time of login only.
My colleagues have create a website and there is a webpage which contains a Tab.
He Implement the tab with the following method:
1.Load all content of the page
2.Use javascript to display those group content as block and organize them into tabs.
3.when user click one tab, then acitve it, and hide all other tabs.
And these functions works very well, but the performance is bad:
1.Load all contents cost lots of time
2.It will show all content at first, and then shrink to a tab control. When the user see this, it might think this is a bug of our system.
The web app uses XML from a web service, which is then transformed to HTML using XSLT. The app uses a HttpModule to get the XML using AddOnPreRequestHandlerExecuteAsync.
Classes Used:
XmlDocument - stores the xml.
XslCompiledTransform - stores the transform, is cached in Application.
Asynchronous HttpWebRequest using BeginGetResponse/EndGetResponse
HttpModule with hooked AddOnPreRequestHandlerExecuteAsync events.
I do not want to use the XPathDocument unless there are no other possible optimizations. It would take some complicated code to get all the XML together without the ability to write to the XmlDocument. There is additional XML that does not come from the web service that must also be added to the document.

The problem here is that instead of using Two repeaters, can we use only one?
We actually need the header to be separated from the contents using a different table row...
Edit: changed rptHeader's ItemTemplate's html element from <td> to <th> to be a little clearer.
I wanna bind atleast 30,000 records in a gridview from a sqlserver table. I want to bind only 50 records at a time with grid view. The grid has also paging and when I click next page then next 50 records should be shown and another next page's click another 50 records.
How can I optimize this thing. I want that If 30,000 records are binding then grid should be work as binded 50 records.
There's so much hype about ASP.NET MVC these days, but the truth is that ASP.NET webforms is not going anywhere for some time. Is there any way for current developers to optimize ASP.NET webforms to perform as fast as ASP.NET MVC?
I have noticed a significant difference in speed between ASP.NET MVC and ASP.NET webforms. MVC is a lot snappier and loads pages faster than webforms. Can I achieve the same with ASP.NET webforms by optimizing it? If yes, what would you recommend?
I have an asp.net mvc application that spawns a Process as follows:
Process p = new Process();
p.EnableRaisingEvents = true;
p.Exited += new EventHandler(p_Exited);
p.StartInfo.Arguments = "-interaction=nonstopmode " + inputpath;
p.StartInfo.WorkingDirectory = dir;
p.StartInfo.UseShellExecute = false;
p.StartInfo.FileName = "pdflatex.exe";
p.StartInfo.LoadUserProfile = true;
p.Start();
p.WaitForExit();
Before going further, I need to know whether, e.g., pdflatex.exe is a managed code or a native code? Edit 1 I need to consider this because: (Hopely I am not wrong...) Each Asp.net application runs in an separate/isolated AppDomain as opposed to a separate/isolated process. A native executable cannot live in an AppDomain.to be continued.. Shortly speaking, I hope my site does not spawn a new process for each request. Because a process is more expensive than an application domain. Edit 2 My asp.net mvc application allows users to submit LaTeX input commands such as $ax^2+bx+c=0$ to be converted to a pdf file rendering an quadratic equation. Behind the scene, this web app will spawn a process executing pdflatex.exe. The job of pdflatex.exe is converting the LaTeX input commands to pdf document.
we have this problem but can't find a solution. We have an application that references something like 24 dlls. When you invoke the application the very first time (after the application is for any reason reset) it takes 25-40 seconds to start loading contents.
This is what we tried:
1. precompile and publish everything in release mode
2. removing pdbs from bin folder
3. put strong named assemblies into GAC
4. set application to debug = false
consider that the whole bin folder is composed by 24 dlls for a total size of 28MB. Just 4 of these dlls are strong named and they are more and less 25MB. Nothing seems changed. What happens EXACTLY when the application is started is something I couldn't find in any book nor forum/blog/post... What can we monitor more to find where the problem is?
I posted a question about using AutoCompleteExtender. It simply shows users all available email addresses when they type in a letter(prefix).
It works, but the problem is it loads to late :( takes around 5 seconds to pull out the list.
So I would like to optimize this

I've been developing a game using Silverlight 4 and silversprite (http://silversprite.codeplex.com/)
This game is HEAVILY content dependent, using a lot of audio and images. My content folder is around 90 mbs worth of stuff. And because of that, my XAP file is around 60 MB, and takes 5 minutes to download from the website before any user can start playing.
I am using Visual Web Developer 2010 to create my site and load the XAP. Is there a way where I can take content out of my XAP and put it in my ASP.net site project? Or perhaps upload my content files to the site's storage?
This would make my XAP file much quicker to download.
Do you know of a library/httpmodule for logging slow loading pages (perhaps for a specific treshold) in an ASP.NET environment?
Google did not yield any results.
It would not be too hard to implement on my own, but why re-invent the weel.
In my website, I am using thread to perform a repetitive process in background. Now the process takes around 30 to 45 seconds to update the database.
Basically the function performs the following:
1) Download the CSV from a website.
2) Parse the CSV and update the database tables.
I want to optimize the performance and decrease the time it takes to 15 seconds.
How can I do this?

i have a trigger that executes asp.net page with method that first retrieves from DB users with needed details and then emails them with information they need like ie. users that does not have an image in their profile. Once i get data from DB i build large string with encoded HTML and assign it to MailMessage.Body tag. There are about 20000 users per action/night who get the mail. Stored procedures just get users based on criteria i need nothing to optimize there (after proper indexes been made). How do i optimize it? Can i create sort of queue in ASP.NET that it will be executed all day long without one time action? Maybe i can use async actions to send few emails per time.

View 3 RepliesI have a master page(created for pop ups as i have a lot..) with the following code:
<body>
<div id = "weadas>
content content content..

<script type="text/javascript">
var content = document.getElementById("weadas");
window.resizeTo(content.offsetWidth + 50, content.offsetHeight + 50);

but then it does not resize properly when poping up. It does work in IE6 but it does not in IE8 nor Mozilla 3.0.
Any ideas of how to optimize that resizing code for asp.net?

basically, the InstellingGegevens table gest filled in by some procedure from another server.
the thing i then need to do is check if there are new records in this table, and fill in the new ones in Instellingens.
this code runs for like 4 minutes on 15k records. how do I optimize it? or is the only way a Stored Procedure?
this code runs in a timer, running every 6h. IF a stored procedure is best, how to I use that in a timer?
