To answer this question, you need to understand the page lifecycle in ASP.NET.
The page lifecycle in ASP.NET consists of several events that occur during the processing of a web page. These events include Page_Init, Control events, Page_Load, and Page_PreRender.
Option A) Page load - This option is correct. The Page_Load event occurs after the Page_Init event and is responsible for loading and initializing the controls on the page. This event is triggered when the page is fully loaded.
Option B) Page_Init - This option is incorrect. The Page_Init event occurs early in the page lifecycle and is used for initializing the page and its controls. At this point, the controls may not be fully loaded.
Option C) Control events - This option is incorrect. Control events occur after the Page_Init event and before the Page_Load event. These events are specific to individual controls on the page and are not related to the loading of all controls.
Option D) Page_PreRender - This option is incorrect. The Page_PreRender event occurs after the Page_Load event and is used for finalizing the page before it is rendered to the user. At this point, the controls have already been loaded.
The correct answer is option A) Page load. This option is correct because the Page_Load event is where the controls on the page are fully loaded and initialized.
