this is the very basic thing for the pages that pages needs to process by on its controls. controls are the basic entities to navigate from one to another autoeventwireup is use to stop the invelaid callbacks for example if u r using the ddl and there is no autopostback property then if in some way there is call using java script then that time it is useful.

For example I set the Autoeventwireup property to false.

Now if i run the appilcation, does the page_init, preinit will be called or not ?

As per your reply it should not call the above events unless you manually attach the event to the page, right ?

if so we can boycott some of the events and makes the performance better, right ?

correct me if I am wrong.

1) For improving the performance.
If we are working in highly traffic environment
then it will affect performance. Because it searches for methods at run time.

2)If we set it true then framework will automatically call events. this can result in double calling of events.

I hope this will clear ur doubt.

Let me change my question.

In which scenario we will set the AutoEventwireup attribute to false in C# and if so Why ?

Hi,
I dont think so, it will help us to implement any functionality.
If we have set this attribute as false. Page_load,init event of Page cannot be executed.
But if we still want to execute it , we can achive this by:

Hi,

AutoEventWireup is attribute of Page directive.

AutoEventWireup="true" is used for page event(For eg:Page load).

For eg:
If we set AutoEventWireup="false"
then Page_Load event cannot be executed.

Usage:
If we set AutoEventWireup="false" it improves performance.
