You need to buy a book and workout the examples provided. When you learn things, go and start the project. Whatever you asked can't be done without having a knowledge on ASP.NET. This site got many articles and sample projects. But as a beginner, I recommend reading a book before you look at the articles.

All the best Smile | :)

AJAX[^] is the answer. To make things easier, use AJAX toolkit for ASP.NET.

What the hell is wrong with you? You ask a question, you're given the de-facto answer and you want a different way of doing it just because you're not familiar. How do you think people learn new concepts?

I would prefer you to use AJAX but here is one other solution.

From javascript make a call to dopostback method with eventtarget and arguments (if reuqired) and in Page Load method check for the event target and call the C# method. Remember this is dirty trick.

JavaScript (JS File)

__doPostBack('CALL_MY_METHID','');

ASPX Code Behind

void Page_Load(object sender, EventArgs e)
{
....
....

// Insure that the __doPostBack() JavaScript method is created...
this.GetPostBackEventReference(this, string.Empty);

string eventTarget = (this.Request["__EVENTTARGET"] == null) ? string.Empty : this.Request["__EVENTTARGET"];
if (eventTarget == "CALL_MY_METHID")
{
  // Call your C# method here and return
  CallMyMethod();
  return;
}
....
....
}

Be careful, there is no Undo Button(Ctrl+Z) in life.

.NET is parsed by the server. Javascript is parsed by the browser. If you have page that is already loaded that you want to process a .NET page, asking the server to do so via Javascript is the best way.

PageMethods vs HTTP Handlers

If we are calling a server side function we can use a number of way.
I use mostly static PageMethods ([System.Web.Services.WebMethod]) using Ajax or HTTP Handlers. Can anyone please tell me which method is better and the pros and cons of each.
I keep performance and response time the first criteria.

Thanks.

AJAX and HttpHandler has no relation. I am not sure what you meant.

We can call server side function by
1. writing a static function ([System.Web.Services.WebMethod]) in code behind using PageMethods.
2. calling an HTTP Handler and returning the string.
by using Ajax.

My Question is which method is faster. I want to know about the pros and cons of each.

I am still not getting you. HttpHanlder can't return a string. It sits in the page request pipeline and handles request.

An HttpHandler can definitely return a string...it just processes an http request and responds with something...doesn't have to be a full page. It does, however, incurr the cost of full ASP.NET pipeline processing, which combined with the effort to write one, makes them less appealing than a PageMethod.

HTML Tabs - Help Required

PageMethods behave as web services, but offer a bit more capabilities than a web service. Unlike a full postback (i.e. UpdatePanel) which will incurr the overhead of processing the full ASP.NET pipeline, a PageMethod has a bit of a truncated pipeline that sets up the context, but bypasses all the rest of the event chain required for a full page postback. An HttpHandler is like a Page (in fact, a Page is an HttpHandler), and as such it will require the full event chain to be fired. A PageMethod is pretty much the most efficient way to perform an AJAX call that requires Session and HttpContext access, but not Request/Response access. A WebService might be faster, but there is SOAP overhead that could hurt performance.

Given that HttpHandlers and WebServices require a bit more work to write than a PageMethod, and the extra processing cost for both, PageMethods are generally the best solution when a full postback (async via UpdatePanel or not) is not needed.

Hi, I am new to HTML UI design. I am having a requirement similar to http://deluxe-tabs.com/templates/[^]

We needs to create tabs like Glass style, Vertical style, etc. For each tab, we needs to have its respective div tag.

Can you please suggest any good article, where I can learn the basics of the same?

Thanks
