Changing The View (.aspx) From The Code-behind (.aspx.cs) Class?
Nov 1, 2010
I 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'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 ...
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 having some trouble, I am very new to asp.net, and the last problem I had, I spent about 59 hours trying to solve, Now I have a new one !
:D well, I guess this is part of the learning process...
Well, in Visual Studio 2010, I clicked New Website. @ C# language, ... The template it gives is pretty nice, it creates a database MDF file, and a login/register setup ready to go !...
You guys can see it live AT CLICK HERE ...
Everything is working, well at least here at the local machine...
There are 2 pages in there, Default.aspX, and About.aspx ... I want to allow ONLY logged in users to view those 2 pages... I tryed a few things, added my account to a role called ADMIN,
In the web.cong I changed Allow"*" to allow"ADMIN" ... still didn't work.. Also, I was trying to avoid using roles for now, and I was trying to find a way to do this for individual pages in the same directory as well... If possible with out touching the web.config file...
I put common code in the app_code directory. I access classes in the code all the time from aspx.cs files by "using" the name space from the C# file in app_code and then referencing the class. Now I want to access a class from an app_code file a aspx file. How do I do this?
i have to give the user the option to upload his own aspx and aspx.cs files on to the server, adjust the hyperlink to point to a page which would do the following display the aspx and aspx.cs files code onto the page without actually rendering the code the browser should not understand anything, and while reading the files to display them the method be such that nothing is processed on the server regarding the code within the files to prevent from unnecessary problems many user would try to cause.
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
I want to know how can I load my files (file1.aspx and file1.aspx.vb) in a container on my index.aspx. My index should have my menu and my container. My problem is that i don't know how do that... options wich i tried:
Iframes: yes work it... but in html 5 iframe will dissapear...
MasterPage: isn't the solution because this refresh all index page.
Ajax: yes.. charge my File1.aspx in the container but i can't call the functions of File1.aspx.vb...
I have a simple login screen that now has to receive its parameters from another web site. I am not sure what we have to do. The other web site, will get the user id and password. the person there is asking me, does he just redirect user tohttp://reports.ourwebsite.com:90/login.aspx?username=Bill&password=testthis is the codes: First is Login.aspx<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Login.aspx.cs" Inherits="Reports.Login" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> xmlns="http://www.w3.org/1999/xhtml"
I can change the color of the return value based on conditional statements but cannot figure out the correct syntax to change the table cell back ground. My attempt is commented out.
How do I correctly declare the table cell? Findcontrol must not be the correct way.
I have a custom implementation of Application_PreRequestHandlerExecute which is applying a deflate/gzip filter to the response. However, on IIS7, this is failing on my "script generator" pages. These aspx pages take in Query String values and return a custom bit of script, changing the response type to text/javascript. I think it is failing because of the way iis7 uses mime types, but I'm unsure how to fix it short of turning all compressio off.
I have a simple user control(.ascx) with a asp label inside of it. Using the codebehind(C#) from a aspx page, how can I change the text of that label? I have tried using public classes in my user control and a few other things that I could think of off the top of my head. Can somebody give me a quick example of how this would be done?
I have a strongly typed partial view named "Address". This partial view contains 'input' fields associated to an Address model class. I want to render it twice in the same view because the user must input the Home address and the Business address.
I have problem with client validation because of the ID of the 'input' rendered is not unique.
Is there a way to set a kind of scope so the id of the 'input' for each partial view has a unique ID that can be recognized by the modelBinder , so that my page post back can correctly organize data into respective address type?
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 need to pass a string from my .aspx page to my .VB class.
i need to capture (device_category; accept_headers : user_agent) and pass the values to my class, i tryed to captur the values on the clas itself but i got an error(valuse are not member of this class..)
I have added a static string variable inside a web page with it's class named VersionBase. The class is public, the variable is public, why can't I simply do VersionBase.MyString from anywhere inside the project like I can do with any other class?
I want to bind an ObjectDataSource to a property in my asp page and I want to do it in the page's aspx code, not in code-behind. I've already done it in code-behind, as follows:
[Code]....
I'd prefer to get rid of the ugly code-behind and just do this in mark-up. Something like [Code]....
This gives me a run-time error: Cannot create an object of type 'System.Object' from its string representation 'SelectedBook' for the 'DataSource' property.Is there a way of doing this declaratively and not in code-behind? Further, what if what I want is to actually use a child property of the property in question? For example, if my Book object has a ReaderComments collection, can I databind to it decaratively in the aspx mark-up?
I am able to access the controls of ".aspx" file in ".aspx.cs" directly without any declaration in ".aspx.cs" or in designer.cs. How is this possible? This is happeing only if I open website as using File System.
Create a new ASP.NET web site application with Visual Studio 2008. So following three files will be created automatically
[code]...
How btnSave is being recognized by .cs file without defining it anywhere as an object of System.Web.UI.WebControls.Button?
i would like to know if there's a combo like jCryption (jCryption) - PHP but for jQuery - ASPX.I mean, I have been searching for a combo to send data both ways (Client-server, server-client) with jQuery to ASPX. The best I found was jCryption that sends data from JavaScrpit to PHP. I need a combo to send data from JavaScrpit to ASPX.
PD: Please don't tell me to use HTTPS, it's not enough to ensure the data communication on a client - server application.
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.
