What is the meaning of “AutoEventWireup”?

Indicates whether the control's events are autowired. true if event autowiring is enabled; otherwise, false. The default is true.

In the case where AutoEventWireup attribute is set to false (by default), event handlers are automatically required for Page_Load or Page_Init. However, when we set the value of the AutoEventWireup attribute to true, the ASP.NET runtime does not require events to specify event handlers like Page_Load or Page_Init.

A thing to be kept in mind is that the AutoEventWireup attribute of the Page directive is set to true by default for the machine (check out the value of this attribute in the machine.config) but set to false by default for a .aspx page). So if it is missing, since by default it is true (i.e., at the machine level), the page framework calls page events automatically, specifically the Page_Init and Page_Load methods. In that case, no explicit Handles clause or delegate is needed.
