Remarks

Notifies the server control to perform any processing steps that are set to occur on each page request. You can access view state information and Web form POST data from this event. You can also access other server controls within the page's control hierarchy.

Note:
If you set a custom template in a control during the Page_Load event, the text values of child controls in the custom template will be lost. This occurs because the form values have already been loaded.
