You can use a data-bound control like the Repeater or ListView, re-bind it to a list of control properties as needed, and let it generate the controls dynamically.

As an alternative, you can use Response.Redirect(".") to re-load the same page.

You can manually call the method invoked by PostBack from the Page Load event   public void Page Load object sender  EventArgs e        MyPostBackMethod sender  e       But if you mean if you can have the Page IsPostBack property set to true without real post back  then the answer is no
