I have Website project, which contains some .ascx and .aspx files. I have added new element <asp:TextBox ID="tb1" runat="server" ... /> in .ascx file and I have wrote some code in proper .ascx.cs file using this element: tb1.Text = "SomeText";. When I compile this project I recieve following error: The name 'tb1' does not exist in the current context.
How can I force to refresh markup of .ascx page? I use Website project and I cannot to change its type to Webapplication.
UPD: I have Website project, which has NOT .ascx.designers.cs files. And I cannot change type of my project to web application.
Unless there's something else happening here, it sounds like the designer.cs file might be out of sync. Try cutting and pasting the control back into the markup, or go into the designer file for the user control and add the TextBox manually:
protected global::System.Web.UI.WebControls.TextBox tb1;
It seems like your design file is not connecting with your code behind file.
Can you confirm if you are defining it as follows,
<%# Control Language="C#" AutoEventWireup="true" CodeBehind="yourcontrol.ascx.cs" Inherits="CompleteNameSpace.ClassName" %>

So this code is in a file login.aspx which literally has some html mnarkup and the below code, so where does this code get loaded from? Where is the App_Web_login.aspx.d7a6dcf1 file located ?
<%# page language="C#" autoeventwireup="true" inherits="stadm_login,
App_Web_login.aspx.d7a6dcf1" enableeventvalidation="false" theme="Niko" %>
The code is contained in a file that is associated with its page. In Visual Studio if you load the project you will see a caret next to the aspx page. Click that and you will see a file associated with that page. That is the code file, or code behind, for the login page.
When the project is built, the code for each page is wrapped into a dll file or code package for the entire project. What you see for the inherits in the page is the base class for the project and also the inheriting of the page class.
So if my project is called FooProject, then at the top of each page where it says inherits, you will something like this (the _base class .page class):
inherits=_FooProject.Login
I downloaded a media player control from the Net then added in my toolbox. Then I drag-and-dropped it to my web page but it's not working...
cc1:Media_Player_Control ID="Media_Player_Control1" runat="server"
MovieURL="./video/yaarian.wmv"
this is my code
Make sure that the path is correct
e.g.
remove ./ if video is located in the child folder named video
or use absolute path e.g. /pages/video/yaarian.wmv
Check the control registration tag and make sure you have the assembly loaded in your bin folder:
<%# Register TagPrefix="cc1" Namespace="MyApp.Controls" Assembly="MyApp" %>
Then, try the following:
<cc1:Media_Player_Control ID="Media_Player_Control1" runat="server"
MovieURL="~/video/yaarian.wmv" runat="server" />
I just inherited a web site that was created by a designer. The site was originally created with all *.html files. The designer renamed all the *.html files to *.aspx files. Hence there are no aspx.cs files created. I pulled the site into a new VS2012 solution. My question is, is there a way in VS 2010 to automatically create the code behind files for a an existing stand alone aspx file?
I don't know of an automated way to do this, but if there is no server side code in the existing *.aspx files then it should just be a case of adding the .cs codebehind files and then wiring them up in the <%# Page tag like so:
<%# Page Title="YourPageTitle" Language="C#" AutoEventWireup="true" CodeBehind="YourPage.aspx.cs" Inherits="YourNamespace.YourPage" %>
Note: This will not create the YourPage.aspx.designer.cs file. (I usually delete these anyway as they cause merge issues - i find it easier to add the controls i need to reference to my code-behind file manually.)
The other alternative is to just create a new "Web Form" for each page with the correct names and then copy and paste the existing markup into them. If you do have server code in the existing *.aspx files then you will need to manually copy it to the code-behind.
Based on what I found here: http://forums.asp.net/t/1229894.aspx/1
Right click on your solution explorer.
Add New Item -> Class File.
Name the file as the name of your aspx eg: Default.aspx.cs
When it asks you the file should be in app_code click "no".
In your aspx in page attribute add
AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="Default"
Similarly in your class file that you just added remove everything. Your class should look like this:
//all namespaces go here
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
}
After you add the new .cs file, you may want to see the file look like a codebehind file (indented, icon, etc). To do so:
Unload the project
Edit the project
Find the new filename (file.aspx.cs) in the section with files.
Add an xml node for DependentUpon.
Save and Close the project
Reload the project
For a file Profile.aspx.cs, the xml should look something like this:
<Compile Include="Profile.aspx.cs">
<DependentUpon>Profile.aspx</DependentUpon>
<SubType>ASPXCodeBehind</SubType>
</Compile>
In Visual Studio 2012: Right click on the project --> click Add --> click Web Form --> Copy the content of your original aspx file into the new WebForm aspx --> delete the original aspx file --> Rename the new one to anything you want.
Now you should have a new aspx file with a code behind file that is ready for use
To save yourself from the drama of manually editing the project file like David Frette details, I suggest you remove the file from the project and create a new file with the same name with a code-behind. Then copy-paste the contents of the original aspx or ascx to the new files.
I'm trying to create a user control and reference it on an aspx page. It works, but only if I reference the individual control, like this:
<%# Register TagPrefix="schmapp" TagName="TestControl" Src="~/TestControl.ascx" %>
instead of referencing the whole namespace, like this:
<%# Register Assembly="UserControlTest" Namespace="UserControlTest" TagPrefix="app" %> <!-- doesn't work-->
I've done this many times yet it's been a while so I might be forgetting something basic. I refreshed my memory with a few tutorials and I think I'm doing the same steps.
I had this in the project I'm working on (.NET 3.5 under VS 2008) and I reproduced it step by step in a very basic project (.NET 4 under VS 2010) - I uploaded it for reference purposes.
I create a new asp.net web project, then Add -> New Item -> Web User Control, and then type some text into the ascx file (just to check if the control is being rendered). I then register the control and try to add it on the page. It works if it's referenced by Src attribute:
<schmapp:TestControl runat="server"/>
but not if the whole assembly is being referenced:
<app:TestControl runat="server" />
Now I can list the controls one by one but it's ugly and I don't want to accept defeat by something so simple, so I summon the might powers of teh internets to help.
I am getting a compilation error on a website. There is a repeater declared in the aspx file as follows:
<%# Page Language="C#" AutoEventWireup="true" CodeFile="MyPage.aspx.cs"
Inherits="MyClass" %>
<asp:Repeater ID="rptMyRepeater" runat="server">
<ItemTemplate>
<tr>
<td>
…
And the class is defined as follows:
public partial class MyClass : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
rptMyRepeater.DataSource = GetMyDataSource();
rptMyRepeater.DataBind();
}
}
}
The problem I have is that rptMyRepeater is not recognised. Note that I copied these files in from another project, and so don't have a designer.cs file.
I came across this question which implies a "Convert to Web Application" would fix the problem. As I'm referencing a CodeFile rather than a CodeBehind, does this apply, or is there a better way? Is a designer file even necessary in this case?
If what you are saying is you don't have just the contents of designer.cs, add this to designer.cs:
protected global::System.Web.UI.WebControls.Repeater rptMyRepeater;
If you do not have a designer.cs file at all, add it to aspx.cs -i.e codefile- and it should work.
Simply this is the equivalent of what the designer file supposed to be doing, controls are not much different than class variables as I see.
A couple of things you could check:
Ensure that your .cs file is set to Compile in the properties
Try using CodeBehind instead of CodeFile
If your page class is inside a namespace then ensure it is fully qualified in the aspx file
If you are using a Web Application Project then right-click and Convert to Web Application
