Well, The best way I would recommend is the 2nd Option. Create a BasePage which inherits from Page class. Define your custom functions there. Now after creating your own page, just change its inheritence from Page to BasePage.
Place the BasePage to your App_Code folder so that any webform you create will have direct access to it.

Thank you all 
sorry if my question is not clear enough. |:
To be more detailed:
In our project, we have a business and data layers. Each has a class with related methods and properties that can be accessed by any web form within the project.
What we're working on is:
Develop a bilingual system, create 2 pages for the same purpose but with different UI language. we're looking for using the same code-behind file for both of them but with a little difference which is in a Button Click event called "Back" that specify different 'Redirect' link.
we tried the the 2 methods mentioned above.
In the 1st option we considered one of the 2 pages class, which has all needed methods and properties in code-behind, as a base class of the other one, which has no methods.
e.g.
Project called: MyProject
page 1 called: Page_1.aspx
page 2 called: Page_2.aspx
Page_1.aspx.cs is a base class,
Page_2.aspx has the following page directive:
<%@ Page Title="" Language="C#" MasterPageFile="MasterPage.Master" AutoEventWireup="true" CodeBehind="Page_2.aspx.cs" Inherits="Page_1.MyProject" %>
Now, I need to know which option is the best in our case?
One more question:
while using the 2ed option, create a base class, we need to define some aspx page controls within the code to be accessed by any methods in the base class. we faced a problem when tring to declare them as a class data member?!
Note: we use a master page, so the controls in aspx pages are placed in a content holder
and because of this we use the following declaration statement:
Label Label1 = (Label)this.Master.FindControl("ContentPlaceHolder1").FindControl("Label1");
the error occured when using 'this': "keyword 'this' is not available in the current context"
any suggestions please?
Thanks again. <=

Hello,
Did you success sharing the same code behind between many pages?
I'm doing the same thing between ascx controls.
Thanks for sharing your experience!

Hi Nicolas,
Yes, we use the 2ed option which is create a base class includes all common methods, and the web forms inherits from it instead of Page class System.Web.UI.Page as following:
Page1 & Page2 are web forms,
Base is class,
in Page1 [the same in Page2] code-behind:
public partial class Page1 : Base
in Base class:
public partial class Base : System.Web.UI.Page
Hope this helps.____________

Did you check the link that I have provided to you. On that article I have mention how to create the App_Code Folder. There is nothing to do with ASP.NET Version.
On Solution Explorer > Right Click > Add ASP.NET Folder > App_Code. Thats All
Again, Please check the link that I have provided to you on last post.
Thanks !

Are you talking about variables that every session can access ?
If so then why not you use Application object.
From your code :
Applicatiion["yourvariablename"] = value;
Now this value will be available globally to every session. Call this value using :
object val = Application["yourvariablename"];

It was quite clear that the OP wasn't talking about session or application variables. Abhijit Jana already answered correctly about three hour before you. You should try reading the previous responses and going for quality rather than quantity in your responses.
only two letters away from being an asset

I think this is wrong.. .
Just see the response next to you, and see actually the user wanted my solution.
We are here to give as many solutions as we can for each posts (so that the base gets enriched and others in future can get reference to it...) rather than to blame each others.
If you see all my responses here in ASP.NET, you will see, I take lots of time to answer each post. I dont post just to increase my post counts.
If you check all my responses, you can see my replies got less no of one liners...

I am not able to create Application variable. I am unable to create appication or session variables. Please help me. I am facing some issues with that.

It seems that you are not clear about what you are going to do. I will suggest you to Buy some beginners ASP.NET Books and start reading. This will help you to longer run. As you are confusing with Classes and Session/Application Variable.
Thanks !

You can use the following to create a variable name.
this.Request.Application["name"] = "This is my application";
To get the Name variable use
string s = this.Request.Application["name"].ToString();
If you are outside the page use
HttpContext.Current.Request.Application["name"]
instead.

The error means what it says. You are using virtual paths, and when you change the location, that causes them not to work, because they try to go above the root of the application.

how are you writing an ASP.NET application if you don't understand what I said ? I can't make it any simpler. The error message means what it says. You're using virtual paths, which means when you move the page location, the file path also changes.

I have a div in my master page. The contentplaceholder is inside that div. My need is to display the page without scrolling the page. If the content in my page is heavy then the page will not scroll in the sense my banner and the footer have fix but the content inside the placeholder will scroll. But my problem is when i give a particular height to the div when i enter the full screen mode the footer will shifted to almost middle of the page..
I want to place the content inside that div and i need the scrolling in both full screen and normal screen mode with my footer fixed at the bottom of the page... And i need this property browser wise... Atleast for safari,IE,mozilla,chrome..
Have any solution for this problem... I will copy my design below...
<asp:contentplaceholder id="ContentPlaceHolder1" runat="server">
|
The class divStyle include the property
.divStyle
{
height: 435px;
overflow: auto;
}
Oopppzz!!!!!!!

Hi to All,
i have 1 problem, i want to implement captcha control in asp.net,i have searched on google also but not found any helpful result.
can anyone tell me how can i use captcha control in login page
Thank you.
|

captcha is never used in login that I've seen. Certainly the built in controls do not offer that ability. There are commercial CAPTCHA libraries, if you don't want to write your own. You will probably need to roll your own login code, also, and not use the built in stuff.
