The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

ASP/ASP.Net Include files

Zones: .NET, Server Side Includes (SSI)

Tags: include, file

I am moving into ASP.Net from ASP. I use a lot of include files and would like to know how to do this effectively in .Net. Most of the sites I do are constructed like building blocks. For instance, the nav menu will be a stand alone page with HTML and Server Side Script, as well as the top and bottom of the page. Each include file has it's own server side vbscript that builds the HTML or data for the specific include file. Below is an example of a home page.

ASP:






<%
server vbscript for this specific page
%>
<table WIDTH="100%" BORDER="0" CELLSPACING="0" CELLPADDING="3" id="TABLE2">
<tr>
<td class=td_blue><b>Welcome to the Home Page</b></td>
</tr>
</table>




.Net:
I've seen the use of <%@ Register TagPrefix="topMenu" TagName="topMenu" Src="topMenu.ascx" %> but this is not the best choice I hope.

The problem is that .aspx pages each have there on codebehind page, and it doesn't appear that you can have multiple code behind pages. So for above example there would be codebehind for each of the include pages. Don't think this will work?

Basically I would like to maintain the building block method. Any suggestions would be appreciated!

I don't think this is very difficult for an experienced programmer so points are low. If not let me know.

in the .NET  is replaced by User Controls
every User control is a file with its own code behid
the code you saw
<%@ Register TagPrefix="topMenu" TagName="topMenu" Src="topMenu.ascx" %>
is exactly the user control register tag in the aspx file
this is the best way to move from asp to asp.net

at the top of each include file put
<%@ Control Language="VB" EnableViewState="False" %>

and save them with .ascx extension

then in your main file put Register directives at the top of the page:
<%@ Register TagPrefix="UserControl1" TagName="Top" Src="top.ascx" %>
<%@ Register TagPrefix="UserControl2" TagName="Reset" Src="reset.ascx" %>
<%@ Register TagPrefix="UserControl3" TagName="OpenPage" Src="openpage.ascx" %>
<%@ Register TagPrefix="UserControl4" TagName="Conns" Src="openconns.ascx" %>

and between the <body> tags put

<body>
<UserControl1:Top runat="server" />

<UserControl2:Reset runat="server" />
<UserControl3:OpenPage runat="server" />
<UserControl4:Conns runat="server" />

</body>

YZlat -

That should work, but seems like a big pain in the ass! Is there a better way to make modules global. Like a menu, or header, so you don't have to rewrite the code on every page....which is not an option of course.

YZlat:

you don't have to rewrite the code, what you do is convert it to UserControl, meaning you'll put <%@ Control Language="VB" EnableViewState="False" %> at the top of the page and change the file extension to ascx. That's the only thing you can do

01.06.2004 at 07:36AM PST, ID: 10052952

alorentz:

One more thing: will each .ascx file reference the aspx.vb file as normal?

Because each .ascx page will have it's own directive at hte top to the appropriate aspx.vb file like:

top.ascx will have as first line:
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="top.aspx.vb" Inherits="localhost.top"%>

menu.ascx will have as first line:
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="menu.aspx.vb" Inherits="localhost.menu"%>

bottom.ascx will have as first line:
<%@ Page Language="vb" AutoEventWireup="false" Codebehind="bottomp.aspx.vb" Inherits="localhost.bottom"%>

Regards.

the user control is file with extension ascx
so the Page tag has to contain Codebehind="yourusercontrolfilename.acsx.vb" no aspx.vb
but for your question - yes the .ascx file reference the ascx.vb as normal

No, top.ascx will have

<%@ Control Language="VB" EnableViewState="False" %>

as its first line. NO <%@ Page Language="vb" AutoEventWireup="false"

I know this may be a bit late, but reading your question I came up with another possible option, or atleast an expansion of the posted solution.

You can put your global code into a class file such as "functions.cs" (or .vb). Create a new public class called functions in the same namespace as your existing code. Within that class you can create public static functions that can be access globally. Here is an example:

namespace MyProgram
{
      public class MyFunctions
      {
            public MyFunctions()
            {

            }

            public static string DoSomething ()
            {
                  // CODE HERE
            }
      }
}

To access your functions in other areas of your program use the following:

      MyFunctions.DoSomething();

I hope this helps.
