I am using the Page Methods of Asp.Net Ajax to call the server method by enabling EnabledPageMethods of ScriptManager to "True". Can we return the DataSet using the Page Methods written on server side?
And also I want to know what are the default datatypes that are supported by the Page Methods to return to client?
Is there anyway I can handle both json and html return types when posting jquery ajax:
For example, this ajax call expects html

I'm using ASP.NET page methods to check for the updates. I'm using inproc sessions and windows authentication in IIS 6. When page is loaded, a session is started. But sometimes when the page method is called it starts a new session(created with current request return true also). Why that might happen ?

I have three cascading dropdowns on my web page and they work fine. The issue I am facing is that there are other controls on the page which cause a postback and with each postback the cascading drop downs are being re-populated (service methods are called) which is becoming a performnace issue.

I am trying to use some page methods on an aspx page. I've done this several times before in other asp.net applications and never had issues until now. I believe that maybe the issue has something to do with the methods be exposed to POST but I'm not entirely sure. Everything on the page loads correctly then once it attempts to make an ajax call rather than hitting the "test" function, the page tries to reload and the page_load method is called again. I chacked the URL string on both cases when page_load is called and both are correct. I am suspicous that there is some need to do with the web.config but I'm not sure what. The application is close to 10 years old and has been grandfathered up all the way to ASP.net 3.5. On another note, I can hit asmx functions perfectly fine its only page methods that seem not to work.

I found a write-up somewhere about the multi-handle slider control and in the post there were the following javascript lines:
slider.add_value(value);
slider.add_drag(value);
Slider, in this case, is my slider control... but how did the person know these two methods exists? Is there an API guide somewhere for the Ajax Control Toolkit?
slider.add_valueChanged(onValueChanged);
[WebMethod(EnableSession = true)]
View 5 RepliesScenario is, I have a tab container inside which I placed 5 tabs and each tab having 4 Cascaded dropDown.Now for changing the tab page everytime refreshed and calling all 5 parent control dropwdown to fill.But can I prevent it in that manner so that for changing the tab only that parent webmethods will be called to populate.In page load itself it will call only the active tab parent Cascading dropdown web method.
View 8 RepliesI am showing state,city, zipcode in cascaded format. I designed cascade dropdown with asp dropdown list controls. I am loaing the citys & zipcode based on selection index changed.. here when I am selecting city the request is sending to server & its loading citys....
I don't want see post back operation on my page when I am selecting city & zipcode. So I am thinking to use Ajax cascade dropdown list to avoid sending the request for each selection.
If I use Ajax Cascade dropdownlist can i cascade the loading of citys & zipcode without using webservices?
If I use only webmethods for cascade dropdown it will work ?
I am using an AJAX dropdownlist control with two dropdownlist. Instead of using a webservice to populate the data, I used the pagemethod to populate. My problem is the second droplist won't populate. I get a server error, 500 in the droplist. The first droplist populates fine.
BUT here's the real kicker. If I reverse the order of the public static function such that GetHelloList2 comes BEFORE GetHelloList1 in the code, then the GetHelloList2 works ...... it just seems like it is only firing one pagemethod event and allowign only one.

Old school coders are used to having every server control create events in the .cs files.. for example.. Getting the Initial load of data, Saving Data, Deleting data... and then binding datasources to the server control..
New school coders want to do it in Jquery + AJAX calls to .svc files... That gives automatic no post backs so that is a advantage... and I think its a different way of thinking.. All of a sudden the UI related events are all being done in Jquery..
What is the most modern and efficient way to go ? How can I convince the old school coders to let us you this new paradigm ? (assuming it is the better way)

I have created a web aplication in the following environment Visual studio 2008, IIS 5.0 & OS:Windows XP. It is working fine in my local system. But when I host this application on the server some of the AJAX methods are not working.

I am building a sort of administration control panel which is basically just giving the end user the ability to manage the database through my app rather than knowing Management Studio. Creating lists of users, creating events that the users can attend etc, nothing too complex. So I am basically building the whole thing using JQuery AJAX with ASP.Net to make the DB connection and what not. My Jquery code just calls a different static method in my pages code behind for each different task, passing JSON back and forth.
From what I've seen results-wise so far, my interfaces are much quicker (almost instant) and even tasks on the server take less time to return through JQuery. But if you looked at my javascript code, you can see the "Page.aspxMyMethod". That means that people can access my methods just by sending a request from anywhere? Will forms authentication prevent this because it goes through an aspx page or what?
