difference between !page.Ispostback & !.Ispostback?

Question

Sanjeeb Lenka · Answer

The two lines are pretty one the same it is just that one is being more explicit than the other. Your Web Page your class inherits of the Page class: http://msdn.microsoft.com/en-us/library/dfbt9et1.aspx And the Page class has a Property called IsPostBack. Since your page inherits from Page it has direct access to all the properties of the Page class including the IsPostBack property. However there is nothing stopping you from being explicit in referencing this Property using Page in the second example.
