37820240The Callback is among the novelties of the ASP. Net 2.0, it can communicate with the server without posting the whole page ..
The difference between Callback and postback is that in the PostBack whenever you click a button, all the HTML of the page and its controls is regenerated (Render).
By cons in the callback is not the case and it is very important! Why regenerate all the HTML page? Is it important to do? when I just want to add a row in my GridView (for example).
So for a web application slightly, the "Render" of a control should be targeted and not overall ..
I mean no need to generate all the html code of the page and its controls.
You can use "Ajax control" but I do not know the code generated behind, so I can control what happens in my application.
To better understand this we will see the page life cycle with 2 modes (PostBack and CallBack)....

P.S: The WebApplication DLL (AspxToCsharp.dll) is instantiated for each client request!
in Page_Load we register the Ajax client script to the client's browser and create a list of string (the source) that contains some names.
when implementing ICallbackEventHandler, two methods are added:The purpose of this article is to create a C # FTP client in Secure mode, so if you don’t have much knowledge of FTPS, I advise you to take a look at this: FTPS.
In the .NET Framework, to upload a file in FTPS mode, we generally use the FtpWebRequest class, but you can not send commands with « quote » arguments, and even if you search on the web, you will not find a concrete example of a secured C# FTP client.
It’s for those reasons I decided to create this article.
