Your application uses a common page format for most of its pages, and you want to reuse and simplify the maintenance of the shared HTML.
Review the HTML to determine what is common on all of your pages, and then create a user control for each of the common sections. The HTML page used as the basis for our example is shown in Example 18-21. Our user control for the top of the page is shown in Example 18-22 through Example 18-24 and for the bottom of the page in Examples Example 18-25 through Example 18-27.
Next, create a base page class that inherits from
System.Web.UI.Page and loads the user controls you
created at runtime. This base page class, along with the user
controls containing the HTML for your pages, constitutes a
“reusable HTML page template.”
Example 18-28 and Example 18-29 show the VB and C# versions of our base page
class that demonstrate this solution.
You can then create the pages for your application by inheriting from
the base class you have created instead of
System.Web.UI.Page and add only the HTML that is
unique to each page. Example 18-30 through
Example 18-32 show the
and VB and C# code-behind file for an application that demonstrate
the use of the base page class.
Most applications use a common HTML design for the majority of their pages, and developers often find themselves cutting and pasting the common HTML in order to repeat the design on each page. Because of the replication, maintenance ...
