This section describes several controls used during development. For more information, see
-- Master page
In ASP. in NET2.0, the master page is a very special file that contains some fixed static la s on the page. areas that can be used in the derived page are given as special placeholders, during system compilation, the master page and the derived page are integrated and displayed as pages with specific functions at runtime. In the code on the page, except for the distinguished code @ Master, it is the control ContentPlaceHolder, where the content of the derived page is displayed. A standard master page code:
1 <% @ Master Language = "C #" AutoEventWireup = "true" CodeFile = "MasterPage. master. cs" Inherits = "MasterPage" %>@ Master at the beginning of the Code indicates that the file is a Master page, which enables the ASP. NET Runtime Library to correctly process the file. The identifier of asp: ContentPlaceHolder is the point character of the derived page. On the master page, you can customize any number of content placeholders.
When a derived page is generated, the content of a normal webpage is no longer displayed in the code, but directed to the master page:
1 <% @ Page Language = "C #" MasterPageFile = "~ /MasterPage. master "AutoEventWireup =" true "CodeFile =" Default2.aspx. cs "Inherits =" Default2 "Title =" "%>You can perform specific development on the derived page.
