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'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 am developing a website which will be having both asp.net pages and MVC pages in it, So I have BaseWebPage class which will be used for both asp.net pages and MVC Views. but My BaseWebPage class is inherited from System.Web.Mvc.ViewPage, So Will there be any code/ functionality break for normal asp.net pages, because System.Web.Mvc.ViewPage is overriding some of the Pagelife cycle methods.
View 1 RepliesI have a 'classic' ASP.NET app (.NET 3.5) with a pretty standard runat="server" style form with server-side controls and an 'Execute' asp:button. In the code-behind, the executeButton_click handler processes some of the other controls, runs a report, and drops the result into an asp:label. So the effect of pressing the Execute button is that the entire page reloads with the report inserted into the label.
I need to change this so that when the Execute button is pressed, the report pops up in a new window with a different layout (ie without the controls and form). If I was doing this in an MVC framework I would just change the view template in the 'execute' action, so the analogue for ASP.NET would be change the code in front, ie the .aspx file that gets used, from the code-behind class.
Is this possible? I know the link between the .aspx and the .aspx.cs isn't extremely tight as it is possible to reuse a code-behind class in multiple .aspx files. So can I set the .aspx file to render from the code-behind?
I am trying to do something such as:
<%= Class1.GetName %>
in my ASPX page, but my class1.vb can't work like this, I have to declare it first in the aspx page, how can I make my Class1.vb file be shared among the whole website?
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 3 RepliesI am on .aspx page and i want to take the width and height of a control from a static class
where i have defined them as constans.
Is there any way to access that class directly from the aspx page?
I know that i can make a method like:
width="<%= getWidthSize() %>"
and inside the aspx.cs to define this method to take the size from that static class.
But i am asking if this could be directly managed from the web aspx page...?
I have a 2D array of doubles in my Default class on my Default.aspx.cs page, like so:
protected Double[,] time;
By the time the page loads, I have populated this array from a database. Now, I want to reference this array in another file (Diff.aspx.cs) to avoid visiting the database again. Also, the data is used in a read-only fashion.
i have a hidden textbox in my aspx page. The aspx page also has a masterpage in the <% @Page> directive.
<input type="hidden" runat="server" name="txtType" id="txtType" />
actually in aspx.cs i am getting txtType.ClientID="ctl00_MainHeaderContent_txtType"
I have a webpart in a webpart zone in this aspx page. In the webpart CreateChildcontrols() I need to access this hiddenTextbox value. I am able to access it as
string TxtValue = this.Page.Request.Form["ctl00_MainHeaderContent_txtType"];
But instead of hardcoding I want to access as a control in the page or form. How can I do that I want to do as looping through the controls in the page but Page.Controls.Count gives 1 and that is MasterPage. How can I get the entire controls in the page and loop through and find the hidden textbox. I also tried as string TxtValue = this.Page.Request.Form["<%=txtType.ClientID%>"] in CreateChildControls() of the webp[art. But could not access hidden textbox like this.
I have a webpage with a textbox, panel and a DropDownExtender, may plan is to dynamically add labels to the panel on load.
and my plan is to do the dynamic adding of labels in a Class.
so my problem is how can i pass a group Label Controls from a Class to the ASPX page Panel.
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?
I have an aspx application with 2 aspx pages. Second aspx page will get opened on click of a button in first aspx page using JavaScript. The problem is, when the second aspx page is getting opened, its Page_load event is not firing. Only when I refresh the second page, page_load event of second aspx page is fired. what might be the problem and what is to be done to fire the page_load event.
View 1 RepliesI wrote a test page that does a bunch of busy work in a method called at page load. This process as I have it now takes around 12 seconds.
If I try to load another page while the first long running page is loading, this second page doing nothing except writing out a world, it doesn't load until the first long running page is finished.
Why is this the case? I would think IIS would be able to handle multiple concurrent connections, it seems crazy that one long running page would stop every other page in the application from loading. I must be missing something or not understand how IIS works.
I would think multiple independent requests would be spawned on different threads. Is this only the case if the requests are from different sessions entirely? Are all requests from a single session bound to a single thread?
I have page A.aspx where I show some result in listview. When I click On Some data on listview I go to page B.aspx. Now the problem is when I click on back in page B.aspx it comes to A.aspx with out previous listview result. Ack requirement is when I come to page A.aspx result of listview has to be there. How do i do that?
View 2 RepliesI work in VS 2008. Whenver I add a server control(Label) and set it properties in aspx.vb and build the solution, I get the error "Label1 not declared". While analyzing this issue I noticed that the event handler statements for the Label1 where not added in the designer.asp.vb file. These statement would actually be added automatically when I drag and drop a control to my webpage.
I would also like to inform the scenario after which this problem came to me. I was working in VS 2008 , VS 2005 and VS 2003 in the same machine.Could this have caused the issue ?
Now each and everytime when I add a control, I am adding the "With Events" code in the designer page to make my build succesfull which makes me to spend more efforts.
Is it possible to set the Inherits attribute of an ASPX Page directive to a class in an arbitrary assembly?
I need to modify an ASP.NET (1.1) application for which the source code was lost. In a new assembly (foo2.dll) I've created a replacement code-behind class that derives from the original class in the site's code-behind assembly (foo.dll). It seems easy enough to set the Inherits attribute of the Page directive to the new class name, but when I do that the web server gives me Could not load type 'Foo2.checkout2'. I am referencing the new assembly in the <assemblies> section of Web.config.
I don't see anything in the documentation to indicate that this scenario is unsupported, but I'm not certain that it is, either.
Original
<%@ Page Inherits="Foo.checkout" language="c#" Codebehind="checkout.aspx.cs" AutoEventWireup="false" %>
New
<%@ Page Inherits="Foo2.checkout2" CodeFile="checkout2.aspx.cs" CodeFileBaseClass="Foo.checkout" language="c#" Codebehind="checkout.aspx.cs" AutoEventWireup="false" %>

i have tried many ways of displaying it but it ends up on displaying the actual comments instead of the code. how to achieve the above. note main concentration is on asp.net and c# using vs08, so j script and ready-made tools be avoided if feasible
