I am currently working on a page that has 13 gridviews in it. Each one is in a control and a separate updatepanel. The time from link click to page load is 20 seconds though and I am looking for ways to load the controls asynchronously so that the page can load and then the data can come after. I have tried a few different methods so far but have been unsucessful so far. I thought about using the Ajax incremental page display pattern but I did not think this would work because it only returns html. I need to load the gridviews in and they need to support pagination and sorting.
I have a scenario which I am looking at where large files which are about 30-40 MB are being FTPed to a server. I am looking at creating a .net screen with the FTP control to upload the file to a Unix server. I need to know how much of a performance hit it is to work with such large files, is it a feasible option in this scenario? I might have to create a .net component for the same and call from ASP application. Is it doable?
how a large ASP.NET webapplication can be structured / designed with "subwebs" !? In other words I want to structure a large web-application where I have a solution with more web-application projects. These projects are more or less independent "modules". One project should be a kind of frame application with shared masterpages, an shared sitemap and and a shared authentication. Later it should also be maybe possible also to integrate loosely older websites (which where written in classic ASP. ASP.NET 1.1, ASP.NET 2.0), but this not so important at the moment
I need to create a method which looks through a large string of text, and determines which words (apart from words like "a" "and" "the") are the most frequently used. I would like to determine which are the top 3 most frequently used words in a string of text...is this possible?
I am building a small mass email application for my department. Which basically emails out a notice to a large list of email addresses. Because the company email server limits the amount of email addresses that can be contained in a single email I have to break the list apart into smaller 100 email groups.
I've create the query to pull all email addresses needed, stuffed them into a collection but I am not sure how to grab 100 emails at a time and send it off to another sub to perform the email send before grabbing the next 100.
I have a project that will be assigned to me soon whereby I need to develop a survey which needs to support 40,000 users approximately. Now we are thinking of doing a staged approach so not all users are on the server at any one point of time. Probably splitting it so we can serve at least a few thousand of users...
I dont have much experience of how I can ensure to serve those levels of users on a server and how to manage this so I am after some advice?
From my understanding I need to do some stress testing on a server and obviously I need some figures i.e. average size of request, average size of response and content of response.
- Do I have to build the database and add records in to see what size is a typical survey row?
- Do I have to build the survey in .NET i.e. by adding controls etc and seeing what size is the page?
- The survey shouldnt be too instensive processing wise, it will be adding information into a backend sql database...
It is a very large .txt file (more than 3M), and produced everyday, the content is user's system log like below:
2007-11-01 18:20:42,983 [4520] INFO GetXXX() SERVICE START 2007-11-01 18:21:42,983 [4520] WARING USER ACCESS DENIED 2007-11-01 18:22:42,983 [4520] ERROR INPUT PARAMETER IS NULL CAN NOT CONVERT TO INT32 2007-11-01 18:23:59,968 [4520] INFO USER LOGOUT
I'm developing chat application on asp.net mvc, in my app, user can create room and invite other join to chat, but don't need to save chat room information.So, I designed to save all chat message ,room information and user info in Session and clear it when owner close the room.I'm worry about stressing server when I save alot of data (include room info, user info, and message) in Session if there are up to 5000 rooms created and alot of messages transfered in that room.Is my solution good enough ? is it ok to save in Session ?
I have a simple web page in ASP.NET / C#. Currently to fully render the data I require calling a block of code that runs on background threads and can take multiple minutes to complete. I've got it to the point (using the async attribute on the page declaration) to execute and return fine with the html once it's done. What I'd like it to do is allow me to return immediately with a 'loading page' of some sort and then have that page be updated when the background work has been completed. Right now I get nothing on the page while the background work is being processed.
I am working on 3 tier architecture: UI, BL, DAL. In my UI i have following code for Asynchronous page processing:
[Code]....
But I want a database fetch operation to be performed in this asyncronous method. And due to 3 tier arch. i am unable to do this in UI Layer. Can anyone guide me that how can I implement Asynchronous processing in 3 tier architecture? Note: If you are going to place EndAsyncWork1 in DAL then show that how can I return a value back to UI layer from this function.
I'm using a CMS, which removes my ability to access the actual Page, I can only program Master pages. I need to set the Async property of the @Page directive on a particular page, but can't figure out how to do so from the Master page.
Just discovered AJAX and the AsyncFileUpload control.I added the script manager and async control to the page, browsed and selected a file but I have no idea where the control stores the image.I went to the AJAX site and tutorials are missing!
we have a classic ASP Webpage for displaying reporting data.
The process is following:
user inputs reporting criteria reporting criteria are passed to a method in a VB6 DLL containing the reporting business logic (generating a dynmic sql statement) VB6 DLL method returns xml data xml data are displayed with xsd transformation 150.000 datarows are displayed in some seconds (less than 10 seconds maybe) Now we want to extend this reporting function and decided to use asp.net (2.0) So I have written a little prototyp application with a SqlDataSource Object and a GridView Control.
A table with less data (about 100 or so) are displayed quickly.
But a view with about 150.000 datarows needs about 2 minutes and ended with a OutOfMemoryException!
The request of the customer is definitvely to display the data on one page like in the old classic asp application!
I'm trying to save some content whenever a button/hyperlink is clicked using jquery.ajax (Using Asp.net 3.5). The logic is as follows:
Through .bind in jquery I bind my own method(MakeLog) to a button click or hyperlink click. The click events of button/hyperlink contain nothing, I need to use .bind for selective controls.Now we have a button whose click event will fire a method, say MakeLog.Code snippet for MakeLog is as follows:
This works fine in IE but in Firefox this is not sending the data back as expected.I tried to identify the issue and came across the following: http://stackoverflow.com/questions/3522944/jquery-ajax-calls-async-false-vs-async-true .What I understand is that, whenver page is redirecting/reloading due to button click or hyperlink click the async call is not working properly.
i m using GridView through n-tier architecture(BAL,DAL etc). Data binding is fine but problem is that there is no page sorting , edit, delete functions are not coming in smart tag.it comes when m using SqlDataSource connection. The many functions will come.
I'm creating a web page that will show a form that allows a user to query a database and then page backwards and forwards through the data. In other words one record of the returned data will be displayed on the form and the user can move forward to display the next record or back to display the previous one.
My problem is that a large volume of data may be returned and I'm wondering the best way to keep this data between postbacks. I would think there would be too much data to use viewstate.
We have a fairly large website with several master pages. Right now the titles are being controlled by Session variables in individual pages and set by the master page. The code is bad and needs to be redone. With the current system, since the master page is executed last, we can't completely overwrite the page title when needed from the page. What is the best way to create breadcrumbed page titles across a large site in ASP.NET with several master pages, without using Sessions variables? Session variables are bad for page titles mmmkkayy.
I have part of a project whereby I need to send 1 to up to 2000 emails from a webpage. One open source bug tracker used a Thread to send emails but it was riddled with bugs. So just want to know if anyone has any ideas of how I can create a procedure that send up to 2000 emails a go?
I was told by one of my colleagues to leave it as one process (normal routine sending one email at a time) as it won't take long to process all the emails anyway. Doesn't seem right and I want to use threading... maybe I like complex routines?
[Extra] I have something like: foreach(string email in emailAddresses) { MailMessage mailMessage = new MailMessage(); mailMessage.To.Add(...) ... SmtpClient client = new SmtpClient(); client.Send(mailMessage); }
We have a html page being rendered in the browser (IE) that causes the browser to hang. The page is generated through server side script (ASP.NET and viewstate is disabled). The page while loading takes a long time (its not a bw issue since we can reproduce it on local machine) and sometimes results in script unresponsive error. On debugging the issue we found that the html size on the client side is 4.73 MB. There's also a lot of DOM traversal (using JQuery) after document is ready (jquery-document.ready). After loading as well, the page simply hangs on any user interaction (scroll, mouseover) etc. A CPU usage spike (25-50% usage) is seen during loading and on any user interaction
...I get an async postback when I click the 'Edit' button for a particular GridView row. This is what I want. In fact, I also get an async postback if I then click the 'Cancel' button for that GridView row which appears after having clicked the 'Edit' button.
However, if I instead click the 'Update' button that appears after having clicked the 'Edit' button, I get a full postback. I have tried almost every GridView EventName
I can find to add to the <Triggers></Triggers> section to get a click of the 'Update' button to result in an async postback, but with no luck.
What EventName should I use in the <Triggers></Triggers> section to get a GridView to do an async postback when clicking the 'Update' button for a particular row?
