I've been trying to send my webservice a contextkey for the first drop down. When I debug the webservice, and I manually enter a context key, i get the correct values back with the value that equals my context key having <isDefaultValue>True</isDefaultValue>.
WebService (part of it that gets data for my first drop down):
i followed this tut http://www.ajaxprojects.com/ajax/tutorialdetails.php?itemid=554 for cascading drop downs, but i changed the sql connections for my linq datasource. VS2010 is showing no errors in my code and the page loads fine too, but the two drop down lists are emptycan anyone scan there eyes over it and see if theres any reason why it shouldnt be working?my code is the same as the tuts apart from it uses LINQ instead of SQL
Now you can execute any code behind function when you receive a response, and because it's async anything short of leaving the page and it will still postback when you get a response.For example, I have a site which display data from a database in a gridview and uses a client side web service to get the time last updated for a database, call the web service client side every second, then, when an update is detected, call a partial postback, alert the user, and update the gridview.Though this really is a hack, so I'm not sure if there any problems with this approach, if there's a simpler and better way to go about it (I'm all ears).
I'm trying to implement an auction website and I search in web the Ajax Push is the best way where I can use! So, I'm finding some samples in web to learn how to implement Ajax Push (comet) in client and server. By the way, I find some samples in ASP.Net Webforms, but no in MVC version. I'd like to find a demo, sample, anything ... that use MVC
i am doing a project in asp.net...i want to retrieve image and logo from database and then pass image and logo as argument in a function but the problem is in retreiving the image from database[i.e the retreived image from db should be in image data-type]...
I installed MS SQL Express 2008 with Advanced Services including Management Studio 2008. When I connect to the SQL server of my provider (shared hosting - one SQL server for many customers), it takes very long (up to serveral minutes) until all DBs are displayed in the object explorer (from which I then have to choose my DB). Somebody told me, the long waiting time occurs because Management Studio first checks rights (whichever rights that may be) with every DB that runs on the server.
But in Management Studio 2005 the behaviour is different - the DB Tree in the object explorer expands immediately! No waiting time! Does anyone know a solution for this? I don't want to install two separate versions of Management Studio just because of that!
I've noticed that once I've instantiated 3-4 objects now, my ASPX page is running slower. The response from the server (which is my own PC) is taking longer.
With one or two objects, the performance is same. After I instantiate 3, it slows a little, and 4 just completely wears it down.
I've read this article: [URL]
that says to avoid using session variables especially storing objects into them. Well thats exactly what I'm doing. My object has about 10 methods(~30 lines of code each) and 20 fields.
My question is, if I want to persist object in memory for each user session, how else could I store them on each postback if not in the session variable>? I can't use application variable because thats shared and not thread safe.
I used iTextSharp to convert my gridview into a pdf document however i want to have my logo on the top right hand corner of every pdf page along with a static title word at the bottom left of everypage generated.
Tried both RegisterStartupScript and RegisterClientScriptBlock, no luck.
I've got an issue where I'm unable to view Ajax controls within the Visual Studio toolbox section What makes this issue even more bizzare is that I'm able to view the controls of the .dll (AjaxControlToolkit.dll) in a test website. I can see Visual Studio iterate through the controls and add them to the tab in one project and absolutely nothing in the other. I've already checked to see if another tab has my controls and done multiple Toolbox resets. Obviously, I need consistency with this and for me to be able to easily add controls to my target website...Does anyone know why one VS2008 project displays controls correctly in one place but not in another project?

I want to show a waiting image/progress bar on page load event. In page load event, some code is being processed for displaying a report which takes 1/2 minutes to display on the aspx page, meanwhile the aspx is being empty and nothing is displyed, this is not so userfriendly. So, I want to show an image indicating page is being processed. I tried searching in google and found some code samples but couldnt achieve my target. How to implement this. Requirement is nothing but: Display an image/progress bar until the report is processed.
I have some difficulties in one of the web based projects that I've developed.
It's a country wide project and database is big, so the waiting time is getting increasing. I tried to write non- complex queries and set up index on some important fields that are being searched as well.
Is there any other way to enhance the efficiency and performance?
I'm using VS2005.I just downloaded .NET framework 4 and so then I downloaded ajaxcontroltoolkit.binary.net4 via [http://ajaxcontroltoolkit.codeplex.com/releases/view/43475](as opposed to ajaxcontroltoolkit.binary.net35 for .NET 3.5), but when I try to load the ajaxcontroltoolkit.dll into my toolbox (as said in the tutorials), I get the following error msg:"'C:......ajaxcontroltoolkit.dll' is not a microsoft .NET module."
I have a page where the user will select criteria from drodownlists and then click the "go" button.I would like to create some kind of progress template or progress-bar so that the user will know that the query is in progress. What are the best and easiest options for this?I just want a simple thing like a rotating sand clock,
Is there a way of stopping the main page waiting for a usercontrol to load before it can finish loading?
I have a usercontrolthat has to do a lot of DB calls which can take a few seconds making the page slow to load. Ideally I'd like the main page to load straight away and then the usercontrol content appear when it is ready.
