I could'nt understand how to define these Properties,Sub and Functions. How i start?
i have an application consisting of two asp.net projects. And i have have a BasePage which inherits System.Web.UI.Page and have the class some core logic which i require in all of my pages(Implemented in BasePage.cs). So all my pages inherit this BasePage.cs . Now can an Webservice inherit the same class apart from the normal webservice class System.Web.Services.WebService

Here When i create object of Class InheritingOneConstruntor value of public field var1 is zero at last. But when i checked step by step through debugging i found that when base class's New() constructor is called, for a moment all var1's value becomes 89. All var1 means at all locations where var1 is used i.e., in base class and in child class.But the moment control exits New() constructor of base class, var1's value again becomes zero. Why it happend ?
I might be asking a dumb question, but I have a client for whom I need to build many websites (10+) (asp.net 3.5) which will all the pages on each site will have the same codebehind, but the sites will launching in different regions and whilst following the same template, will have different content.I have built and launched site 1, and sites 2, 3 & 4 is nearly live, but it occurs to me that as all the sites are basically the same, the code is going to get more complicated to update as it will be duplicated, so if I need to do a bug fix on one site, I'll need to do the fix on all websites (and this is going to get complicated.)
I was wondering if it possible to somehow create a class library of all the current aspx.cs files, reference this dll in each website and then inherit these classes into the .aspx.cs files. So default.aspx in each site would still have a CodeFile of "Default.aspx.cs", but Default.aspx.cs would inherit the corresponing class from the dll:
using WebPagesClass;
public partial class _Default : WebPagesClass._Default
{ }
The reason for doing it like this is that if I need to change any code on a specific website (for minor changes in languages for instance), I can override the page functions and change the parts required. For all other pages which have not cha, I can just copy from a single website.Is this vaguely possible? If not anyone one got any killer suggestions of how to manage so many websites from a single codebase?
How does we inherit data from one class to another class using Inheritance in practically using c# .net show me some examples. My doubt is we create one method in class and we will call that method when ever it is neccessary in same class , But if we want to call the method and use that properties in another method in another class what is the process?

I'm just starting out learning ASP.NET. From what I understand, ASP.NET differs from old school ASP in that the logic code for a page exists in as separate file rather then being embedded in the ASP page. So when a user requests a page like ShoppingCart.aspx the server reads the directive at the top ...
<%@ Page Title="" Language="C#" MasterPageFile="~/Styles/Site.Master" AutoEventWireup="true"
CodeBehind="MyShoppingCart.aspx.cs" Inherits="TailspinSpyWorks.MyShoppingCart" %>
This tells the server what file and what class in the file is associated with the page. The code behind class also has member variables that correspond to each control on the page, and provide a way for code in the code behind file to manipulate the controls.
First, do I understand this correctly?
Second, could a site be setup with two separate ASPX pages with identically named controls, which both had a directive pointing to the same file and class? Would you even want to do this? Both pages could have the same functionality but a different layout. I was thinking this could be a way to create separate "desktop" and "mobile" versions of a page with out duplicating content in the code behind files.
I guess ultimately what I'm wondering, is if there a way to define an abstract page? Say create an abstract page definition that says a page must have controls "cart_list", "total_lbl", but then be able to have multiple pages that inherit from this abstract page?
I have Page, MasterPage and UserControl in my project.
So I create basepage class and share some logic, then inherit from System.Web.UI.Page. My problem is I want use single basePage for any type of UI content.
I want to know, how to inherit a class within the form/page?

am currently working on a web application, whereby I want to add code to the Application_BeginRequest method of the Global.asax file, without adding code to the Global.asax file, which sounds a little crazy, let me explain a bit more.If anyone has ever developed in sitecore before, they would have seen that the Global.asax file has empty methods, however it has 'using Sitecore;' and the global.asax file provided does not inherit from System.Web.HttpApplication.
View 1 RepliesI have a user control (uc1) which inherits from uc2. uc2 has a user control (uc3) declared in the markup. I am trying to access uc3 from uc1 but I get NullReferenceException. I thought due to inheritance uc3 would instantiate but looks like I am missing a step.
Clarification:
How does the child user control inherit the markup from the base class? The server controls in the base user control are null in the code behind of the base user control. Why?
Recently, I tried to get my Web Service class to inherit from a custom base class that inherits from System.Web.Services.WebMethod instead of the System.Web.Services.WebMethod directly.
However, I've been getting Error 500.

View 4 RepliesI have been trying to find a way to declare two classes using page directive, but it seems like mvc framework doesnt support it.
I have got :

which shows the list of the contacts including edit delete and create option.
What I need to declare another model class which is FileRepository.cs for uploading files on the same page. In this case the page directive should be like:

Is there any way I can incorporate both into one as the first is coming from the database.
