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 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
View 4 RepliesI 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?
I want to know, how to inherit a class within the form/page?

I'm fetching some settings out of the database based on a value passed from a query string. Out of these settings, a few will be used in master page, few on my Page and few in my user control (say login control which is a web user control).I've an entity class MySetting for it and there is a method in my data access layer which returns me an instance of MySetting when I pass the value I got in query string.
I don't want to fetch settings from the database multiple times for one request. I'm using asp.net web forms with C# and sql server.

I have a masterpage that uses an external .css file to set the masterpages apperance across the site. Now I have eight pages on my site and I use the masterpage for seven of them. I have a single page I do not wish to inherit the apperance and layout of the masterpage and so was wondering how would this be done?
View 6 RepliesSenario: Masterpage with a UserControl and a child ASPX page
In the past when using this senario I've used an Interface as a way to pass a value from the UserControl (embedded in a master page) to the masterpage code behind then consume that value in the child aspx page.
My question is now that asp.net 4 have arrived is this still a good way to achieve this or is there another or perhaps better way to do it? I've read somewhere that perhaps "delegates" is perhaps another route to take.
have a look at the code:

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 have MainLayout.master that has UC_Menu.ascx on it.
I have a page named Customer.aspx that uses MainLayout.master. Customer.aspx also contains a UserControl named UC_Details.ascx.
How can I have UC_Menu.ascx call a function that is in UC_Details.ascx with this scenario?
I've seen a few similar examples, but none that match this type of layout.
Currently I'm doing common functionality required throughout my site inside of my masterpage. What I want to do is move this functionality to a BaseClass so All my pages inherit from the Base Class. However, I'm not sure how to set this up interms of c# code with regards to Using a Base Class and then having a masterpage applied to my aspx pages that i create.

i want to know, can one aspx page have two or more code behind page?
like if i have page collge.aspx, by default it will inherit college.aspx.cs, i want to know can't it inherit more then one aspx.cs. If not then why?
I want to inherit more then one class is there any method ?For instance in login.aspx page:
<%@ page language="c#" codefile="nishant.aspx.cs" autowireup="true" inherit="nishant"%>
now code behind file
nishant.aspx.cs:
class nishant
{
//code...
}
class bill
{
//code.....
}
now i want to inherit bill class then how i will ?
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?
Following is the code to insert userName from session and PageName into table to keep record that how many times a user does hit a particular 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?
I have the following situation:
A MasterPage MyMaster.Master
A Content Page Content.aspx
A UserControl MyUserControl.ascx
MyUserControl.ascx is being used in Content.aspx and is being added programatically. The content page is using MyMaster.Master
MyMaster.Master has a variable which I can access from Content.aspx as I have the @MasterType directive set. What I am wanting to do is the following:
1) Set a value in MyUserControl.ascx
2) Access value from Content.aspx
3) Set value in MyMaster.Master
Step 2 is implemented in the PageLoad of content.aspx as follows:
Control ucControl= LoadControl("/UserControls/MyUserControl.ascx");
UserControls_MyUserControl myUC = ucControl as UserControls_MyUserControl; [code]....
The PreRender handler just sets a value in MyMaster.Master to true. In MyMaster.Master I check that value in PageLoad and try display something if it is true. This does not work.I suspect it has something to do with the Page Lifecycle, but I cannot seem to find which part is wrong.
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.

<System.Web.Services.WebMethod()> _
Public Function GetSessionID() As String
GetSessionID = Me.Session.SessionID
End Function

public property Property2 as string

I've seen code to handle MasterPage events in the content Page, but if I'm loading a UserControl dynamically into the Page, can I handle the event in the UserControl instead?
Basically I have a button on the MasterPage, when it's clicked I need to make the UserControl do something, such as display text or change a value in a form.Failing that, is it possible to make an event from one dynamically loaded UserControl fire in another on the same page? I could then replace the button in the MasterPage with one in another UserControl
