the designer give to me .aspx file Website without .asp.cs now i can't make any change because i don't have .CS file from .ASP can any one help me for getting .CS file by the way i already open the file by visual studio but just .aspx without seeing the design code
If you right-click on the .aspx file is there a context menu item named "Convert to Web Application"? If so click on it and VS should generate the designer cs file for you provided the .aspx file doesn't have errors.

I'm very new to asp.net ( but an aged PHP developer) ..
I'm now in a situation where I should do some small modification in an online aspx script(using vb.net).
I downloaded the whole site and opened it in visual studio, all the modification I had to do is to make a redirect to another external page after succesful login,I determined the place where I should do my modification inside a file named login.aspx.vb , and added this line in it:
Response.Redirect("My URL Here")
And then uploaded only the modified file again, to get no change at all.
I even tried to modify the success msg that appear after successful login and re-uploaded it to find no change at all ( still showing the old message)
Is there some step I'm missing before uploading the page?
You will need to compile the project, and if using visual studios you can just hit ctrl shift B and it will build the entire solution. Visual studio detects which project in the solution has changed and will compile it. Then do as the other answerer says and upload the .dll file which is a container of your compiled code that will be referenced by the host you upload it to when there is a request for it. (A container is a definite over simplification for more details check:
What is a dll?
In ASP.NET there are two types of projects.
Web application project
Web site project
In the first case, when you edit a .vb file you need to compile it with Visual Studio and upload the generated .dll file created in the bin folder.
In the second case you can edit the .vb files and upload them and IIS will compile them.
Based on what you wrote, you are in the first case. In that case you need to have the project / solution files to make any modifications in the .vb files. If you don't have access to those files you could inject some code in the .aspx or .ascx files.
For example:
<%
Dim flag As Boolean = false
// Write some code to set the flag
If (flag) Then
Response.Redirect("~/default.aspx")
End If
%>
Using <%....%> you can write code to execute when the page starts to render. This is a bad practice since because it has poor performance since the code is parsed and executed at runtime, while the code in .cs files is already compiled.
But if you don't have the project files you could do minor changes with this hacky approach.
Edit: If you are in the first scenario, you need to build the project and then upload its .dll file which is in the /bin folder. For any changes in the code files you upload only the .dll. If you change the .aspx, .ascx, etc files you need to upload those as well
I am using visual studio 2012. I have created a directory named "Handler" inside my project and added an aspx file along with .cs file (both downloaded from a third party tool) to it. All code is working fine.
Now, I have published project to another directory. In published directory I have marked that the in side "Handler" folder aspx page is there but not the .cs page.
Now, when ever I am requesting the aspx page inside "Handler", I am getting error 404 xxxx.aspx page not found. Now, if I am coping the path and hit the url for that page then I am getting error that xxxx.aspx.cs file not found.
As per my best knowledge, whenever we build the project, all the code will build to dll in bin folder. Then why this file is required .cs file?
Thanks.
This will depend on the attributes of the #Page directive of your aspx page
I guess your third party page #page directive holds a CodeFile attribute.
CodeFile attribute states that, even though the .aspx.cs gets compiled (let's say it just gets checked) in Visual Studio, the result of the compilation will not be put in the dll resulting of the build.
The .aspx.cs will be compiled, along with the .aspx upon first invocation.
This allows to edit your deployed aspx.cs and have the result available immediately (which can be seen as handy, or risky)
As per my best knowledge, whenever we build the project, all the code
will build to dll in bin folder. Then why this file is required .cs
file?
This is the case when being in the default case, having a CodeBehind attribute in the page directive,instead of a CodeFile attribute
See CodeBehind and CodeFile attributes in documentation for #Page element
Note that you can use CodeFile attribute in Web Application Projects. I do it all the time.
I upload 2 page and downloaded same page.I added 2 more control in that file.But my aspx page control are not visible in my .cs file.When I am compling it,error occur on cs file(ddlbrand is not exist in current context).I am using vs 2005.I don't have designer file.(Only aspx and cs file).
Check if your controls are well formed, if the problem exists than I think you can't do that without the whole project and the solution file. You need to make changes in the project with visual studio. All the controls you add in the page are also added to the designer file.
Web Application Projects compile the .CS files as part of the build, and compile the ASPX's on the fly referencing your pre-built codebehind DLL - that's why you have to recompile if you change the code behind.
No designer file means you are working in ASP.Net Website project.
Check your aspx markup it must be missing some closing tag or some important parameter like runat="server"
I am quite new to .NET development and I am just wondering how does it work?
My undermentioned points are:
While developing ASP.NET application, under the project we have files like:
pagename.aspx
pagename.aspx.cs
pagename.asp.desiger.cs
After adding certain functionality to pagename.aspx page, assuming I have the development required web application (this is not my concern, what is developed)
Now I'm going to deploy this application, I use web deployment MSI which creates the required files in the one folder called folderdelopyed.
This folder contains the files required to support this application but interesting does not contain pagename.aspx.cs and pagename.aspx.designer.cs files.
My question is if folderdelopyed does not contain .cs file, then how does it work to run the segment of code which I have written in this file called PageName.aspx.cs?
The code in your cs files gets compiled into a dll.
For Web Application projects this is one dll
For Web Site projects, this is a dll per page.
All of the code is now in the dll's in the bin folder of the website.
You can use a tool like ILSpy (http://wiki.sharpdevelop.net/ILSpy.ashx) to look inside the dll's and see your code.
In the old days, for classic ASP, the script used to be embedded in your page - a mix of code and HTML, and was interpreted at runtime.
I like the new way more :-)
ASP.NET code is compiled into Dynamic-link library files, also known as DLL files.
The code you write in your code behind, which is the files with .cs extension, is compiled and put into whole new file, with .dll extension - and that file is copied to the server, to the BIN folder of your site.
Depending on what project type you choose, it's possible to have several DLL files for the web application, changing in every build - see dash's answer for more details.
On every .aspx page you have referece to what DLL file to use, as the very first line. For example:
<%# Page Language="C#" AutoEventWireup="true" CodeBehind="pagename.aspx.cs" Inherits="MyNameSpace.pagename" %>
In this example, the Inherits part determines what DLL to use. How? By the namespace, which is also the name of the DLL file.
When the above .aspx is requested by a browser, the .NET engine will go to the BIN folder, look for MyNameSpace.dll and in there look for class called pagename that inherits from the base Page class - all the rest is typical life cycle of ASP.NET page.
let me to say you something more Amazing.
you can hide your aspx file too.and put their content in to dll as same as your cs file put in dll.
you can make k aspx that just contain an address to the ddl file and no html body :D
that was greate!!! not only you can hide your cs file, you can hide you aspx file too :D
i have some files with extension aspx.cs.
i tried opening them with visual studio c# 2008.
but all that opens is the code page, and not any design page.
what should i do?
i have to work on that project.
how to open those files, in which program/software?
please help.
Open the project .csproj or .sln file if there is one
The design files end with an extension aspx. The aspx.cs files are the code behind files and do not contain any design elements. Open the .aspx files in visual studio and you will have the proper design page.
The aspx.cs files only contain the code living behind the aspx files (that's why they are called code-behind files). If you want to be able to see the design you have to open an aspx file with the same name.
For example, if you have customers.aspx.cs, it contains the code-behind of a page called customers.aspx.
If you only have aspx.cs but not aspx, then you have a problem, as probably you lost files of the project.
Hai!!
.cs files are code files .aspx files are desidn files where you can switch from asp tages to asp design view but .cs files are c# code file that has no design
Happy Codding
Jay
For the Design File in .net Extension is only .aspx, Please open .aspx files instead of .aspx.cs Files
