Ajax/Jquery code on UserControls

Posted By:      Posted Date: September 03, 2010    Points: 0   Category :ASP.Net
 
Hello,I have some user controls where I would like to add some javascript that uses Ajax and Jquery technology. Also these scripts should use Sys.WebForms.PageRequestManager.getInstance().add_endRequestand other functions of the Ajax framework.In the past I have added the related code to the hosting aspx page but it becomes a problem when re-using the same control in multiple aspx.Which are the best practice to follow in this case?Regards

jQuery $(document).ready() and ASP.NET Ajax asynchronous postback

  
Many call it the ASP.NET jQuery postback problem, but using the technique below should make it no problem anymore. $(document).ready() isn't called after an asynchronous postback. What this means? You lose the functionality that should be executed within $(document).ready() after an UpdatePanel rendered its contents after an asynchronous postback.

call JavaScript - jQuery code from ASP.NET Server-Side

  
jQuery got so close to me lately that I can see myself adding the scripts to my project almost unconsciously. The thing is, jQuery is very useful for me, in almost all situations and it has been a do or die enhancement for all my project since I first put my hands on it.

Of course while using it, you encounter few situations which need a bit of research to solve, mostly when you are trying to combine it with some other technologies like: UpdatePanels and ASP.NET Ajax. For instance there are many situations when I would like to run some jQuery magic based on some decision that I make on the server side.

Making Ajax Callbacks to the Server Using jQuery with ASP.NET

  
In the first part of this article series I introduced jQuery's functionality and how it provides a rich client side programming model. This time around I'll expand on these concepts and show you how you can use jQuery in combination with ASP.NET using it as an AJAX backend to retrieve data. I'll also discuss how you can create ASP.NET controls and otherwise interact with jQuery content from ASP.NET pages in WebForms.


jQuery is just a JavaScript library so it will work seamlessly with ASP.NET both from page code as well as through backend driven code using the Page.ClientScript object or ScriptManager. You can use jQuery on its own as a client side and Ajax library that communicates with ASP.NET or you can use jQuery in combination with ASP.NET AJAX. The two actually complement each other quite well as jQuery provides functionality that the ASP.NET AJAX library does not and vice versa. For the most part the interaction between the two libraries is trouble free except for a few very rare edge cases.

Using jQuery to directly call ASP.NET AJAX page methods

Use jQuery and ASP.NET AJAX to build a client side Repeater

  
By sending only data to the client, you can profoundly reduce the size of what you send and see a substantial increase in performance. You also allow yourself the ability to easily add features like light-weight sorting and paging on the client. This can not only improve your users' experience, but reduce server load and bandwidth requirements.

jQuery live() and ASP.NET Ajax asynchronous postback

  
The issue is that normally $(document).ready() is called when the DOM is ready to be manipulated. But this doens't happen after an ASP.NET Ajax asynch postback occurs.

This means that the initial jQuery bindings won't be automatically available after the asynchronous postback is over. I underline "automatically" here because my last post describes more possibilities, how this issue can be worked around.

Using JQuery to perform Ajax calls in ASP.NET MVC

  
The muscle behind the actual asynchronous calls comes from JavaScript. I looked around at a bunch of existing JavaScript libraries and settled on JQuery because of the way it leverages existing CSS knowledge. The three things that the library should do easily are:
