Why master page doesn't have PreInit event in ASP.NET?
Master pages inherits:System.Web.UI.MasterPage
and as per the design of this MasterPage
class no such PreInit
event is defined for this class.
Master pages are derived from Control class as seen in below hierarchy:
System.Object
System.Web.UI.Control
System.Web.UI.TemplateControl
System.Web.UI.UserControl
System.Web.UI.MasterPage
Therefore as can be guessed now, Master pages behave and in essence are treated like a control and have events similar to other asp.net server controls.
