I have an application build using asp.net in sharepoint platform, however the paging and sorting features in gridview failed to function properly in Offline Explorer (Metaproduct) environment, an offline browsing software.
anyone have encounter the same problem?
Thanks
Assuming I have understood your question correctly and you are using something similar to google gears. Paging cannot work offline.
The concept of paging is where data is retrieved from the server 'as required' rather then when the page is loaded - which obviously cannot work if you are offline.
Without seeing any code its hard to provide specific advice but basically you would want to make sure that the page that is being loaded contains all the data necessary for the gridview to display. This would be done by either rendering the gridview straight away with all data or alternatively loading the data into a javascript array.

I have searched the internet for 2 days having found no answer to the below requirement. What i found most were GeckoFX and CefSharp which are external packages and not installed libraries. How can this be done?
I have been asked to do the following:
Use a suitable library function out of the set of libraries installed with the .NET platform. You must not use the C# WebBrowser class but perform the required HTTP-level communication directly from within your code. The code must clearly identify the HTTP-level client-server communication and must explicitly manage Home page, Favourite, History Lists and Tabs.
Optionally, you may add functionality to render a web page, but there must be an option to disable this functionality and to show only the raw HTML that has been retrieved.
Thanks
What have you attempted so far and what problem are you encountering?
Maybe read this first :)
Currently it sounds like you have been given an interview or homework task that you dont know how to solve. If so, then you should have some idea on where to start or you are in the wrong course or job interview. If you want help, then try to solve the question yourself and ask for help when you are stuck. Tell us what you have tried, show the code you currently have and let us know where you are stuck or what doesnt work as expected.
Where are you stuck? Fetching the webpage? Building the user interface?
My website has a lot of menus and submenus in its index page and these submenus are loaded from the db.Ajax is used to load the submenus. So its taking a lot of time to load the full page. How will i reduce the loading time.I am using asp.net mvc3 and sql server 2008 database
It's very hard to tell what could be the bottleneck in your solution without actually seeing it, but it sounds that you can benefit greatly by doing caching, in ASP.NET MVC it's quite easy to do, here is another great tutorial on the subject. Oh and remember -> “There are 2 hard problems in computer science: caching, naming, and off-by-1 errors” ;)
There are many things that could be going wrong and causing your application to run slowly.
I’d recommend you turn the trace feature on because that will tell you what may be wrong. As Dimitar Dimitrov already mentioned you can try to cache the query in some way so you don’t have to retrieve it every time.
Another option would be to optimize the query so that it fetches all menus and submenus in one query.
But again, don’t do anything specifically until you’ve profiled your application to see where specifically is the issue.
I am trying to put together a winform app that also has a web interface that can interact with events generated from within the winform portion of the app. I am successfully running the cassinidev server from within the app and asp.net pages are being processed but I am still running into a few obstacles and I am not sure if they are even possible???
I am unable to use code behind pages. I have added the appropriate
attributes to the page directive but I still cannot access controls
from the aspx page.
I am unable to access classes from the web portion of the app. See
screenshot...
Maybe what I am trying to accomplish is not even possible but if anyone can help to point me in the right direction I would be most grateful!
I'm pretty sure you can't do that since the only thing you have available is the "website path" option.
You do however have the source and if you find some way of sharing data (maybe using the ApplicationPool) you could probably do that...but i'm guessing you'd still need to cast that data on startup to a static variable in your website.
Seems like too much work 2 me.
I'd suggest selfhosting WebApi as well and then just using that as the data layer of your website.
Both can be hosted in winforms and webapi CAN share static data directly from your code :)
I'm having some problem finding the source of the problem, but here it goes, maybe you know the magic answer.
I'm running this asp.net site with an AJAX updatePanel on my local machine, and everything works just fine, since it's where I developed it. Now, a few days ago, I uploaded the files to my web-host and assigned every single DataBase, and there is no error messages, even though it's still set to debug mode. There is a problem though, whenever I click an element which triggers my asp.net AJAX updatePanel to update, the whole site is updated(which it should not, only the Panel), and my jQuery's (document).ready is called every time as well.
Thank you for any help, I have no idea why this does not work online, nor' do I know why it does work on my local machine.
I have choosen not to upload the code, since I have no idea where the problem might lie, please feel free to ask for the code and I shall reply :)
Have you checked that your web host either:
a) Is running .net 3.5
b) Has the Ajax extensions for .net 2.0 installed
...and that you are testing locally with the same?
I'm trying to do load testing against an ASP.NET web site and I need to be able to parametertise field value of a page to test different code paths.
I had great success with JMeter when load testing a JSP web site before. However, because ASP.NET encodes all form values in the ViewState, changing control values does not really work.
I Googled this problem and people said the web testing tool in Visual Studio Team Tester Edition works well with ASP.NET pages. However, it cost quite a bit so I am just wondering does anyone know how to get around the ViewState issue with JMeter or WAPT?
I've used WebLoad before. Its scripting language is basically JS, so you may be able to find controls on the page using JS and invoke them as part of your load script.
WebLoad is free.
I've figured out how to do this, basically you cannot simply record a static script with JMeter. What you need to do is to record a request, send it, capture the viewstate in the response and send the viewstate back in next request.
If you need more details, I've documented how to do this along with some screenshots on my blog post
As webapps get more complex (ViewState, AJAX, etc) it is tougher and tougher to use traditional load testing tools. That's because they try to jam a ton of virtual users on a very small amount of hardware resources.
My company, BrowserMob, took a different approach. We build a load testing service that uses real web browsers to drive load. Your scripts end up being essentially functional tests (specifically Selenium scripts). My background has been in Selenium for some time (I created Selenium RC and founded OpenQA.org), so as soon as cloud computing made it possible to rent the 5TB+ of RAM necessary to do this, I jumped on the idea :)
