In my deployed web application I am getting the following error:
CS0103: The name 'releaseLionButton_Click' does
not exist in the current context
It identifies this as the offending line:
<asp:Button ID="releaseLionButton" runat="server"
Text="Release the Lion!"
OnClick="releaseLionButton_Click"></asp:Button>

I am using TFS to build my MVC app. I cannot do it because I get lots of compile errors. I am using version 4 of .Net and MVC 2. On the build server I have the .Net framework 4.0 installed. It has been suggested that I should also download the MVC framework as well, but when I look on the net all I can find is this MVC framework; http://mvcframework.codeplex.com/ which does not seem to be relevant and does not work anyway.
One of the assemblies I am missing on the build server is System.Web.Mvc dll.Typical error messages include; "The type or namespace name 'Mvc' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)"What do I need to do to fix this?
Every once in a while, when I'm editing an aspx or ascx page, Visual Studio will start telling me there is an error on the first line of my file. For instance, right now, it is saying Argument missing on line 1. That line is just your typical header, with no apparent problems (to my eyes), and I hadn't even changed that one when the error started appearing.
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="MyControl.ascx.cs"
Inherits="MyNamespace.MyControl" Debug="true" %>
Unlike most compile errors, the build still succeeds. (At least this time it did.)
It's worth noting that no other errors or warnings are thrown by this file or its as[p|c]x.cs
Sometimes, to get out of it, I am forced to undo my changes until it disappears and carefully redo what I wanted. This time, grasping at straws, I cleaned and rebuilt the solution. While I was typing this, the error disappeared, sometime after the rebuild finished.
I have a suspicion that it often happens when I tinker with the databinding in my markup. Sometimes it seems to appear if I'm missing a space inside a tag before its closing slash, like so:
[...] Text='<%# Eval("Field") %>'/>
versus:
[...] Text='<%# Eval("Field") %>' />
...But that doesn't seem to have been the problem in this case.
When coding PHP and Perl, sometimes the interpreter would throw an error referencing the very last line of the file. Over time, I learned to look for imbalanced brackets and other delimiters somewhere up above. This problem in ASP.NET feels similar, but stranger, since it's the first line, and not just something amiss above, cascading down to the bottom. Or is it just Visual Studio getting temporarily confused? Can any pros shed some light on this problem, with reasons why it happens? I'd like to have some logic (as opposed to my own built up superstition) to throw at this the next time it rears its ugly head.
I have an ASP.NET website where the pages call a few components in DLLs. I need to change the signature of a method in the component, and short of doing a text search, don't know if this will break any pages or not. IMO, this is the weakness of web programming -- you don't get the benefit of a compiler telling you about syntax errors.
But it doesn't need to be so. Does anyone know if there is a way to run a spider over a website watching for compile errors, or perhaps some tool that would compile all the .aspx files in a folder structure looking for compile errors?
This is merely for syntax checking -- not to actually pre-compile the website.
EDIT It looks like aspnet_compiler is being recommended. I don't use Visual Studio projects for the website -- it's grown over time with my own templating system (back before Master Pages were available). So something that would run aspnet_compiler over all the files in a folder might work...
I have a drop down with different domains(domain_id column) and a textbox (TextBoxComment) for comments. What I am trying to do is select the area, input a comment, click the button and have it save to the db. My connection string errors on compile.

Working through Steven Sanderson's excellent Pro ASP.Net MVC Framework book.I am trying to reference the TempData collection to display a message after an item has been successfully updated and so have placed a reference to this on my Master Page.[Code]....
This is giving me the following compile time errors:
Error 1 The name 'TempData' does not exist in the current context <programme location>
Error 2 The name 'TempData' does not exist in the current context <programme location>
If I reference TempData on a content page it compiles (and works) fine.
I have a VS 2008 solution. I need to copy an existing .aspx page and re-name it to something else (need to make modifications to that newly copied page). But I keep getting compilation errors saying that duplicate text boxes exist. Can't I have control on different .aspx pages with the same name? How can I do this elegantly?
View 4 RepliesFor the first time in my career, I'm working on an ASP.Net (v3.5) project that has been set up as a Visual Studio 2008/10 Web Site Project.
I'm not keen on this way of working this way for various reasons but for the moment and until such time as the company sees the virtue in working in an environment with namespaces, designer and project files etc., I have to continue with the existing codebase.
I've run into some odd issues since I began this but perhaps the oddest one of all is that althought VS lets me build the code, it doesn't reliably pick up compilation errors so these are not noticed until runtime.
I know the website model allows dynamic/hot compilation when a request is made for a specific but I can't see why it wouldn't do this when I manually (F5) build/rebuild the project. Its immensely annoying as you can imagine and I can't find a workaround.
I have a C# web forms ASP.NET 4.0 web application that uses Routing for URLs for some reason custom errors defined in the system.web section of my web.config is entirely ignored and it will fall back the IIS errors.
This gets entirely ignored

This would be a minor inconvenience except that by the fact it falls back to IIS native instead of my application it completely circumvents Elmah logging my 404 exceptions correctly.
I have an ASP.NET website that worked fine using and debugging in VS2008. I went through the upgrade process opening the solution in VS2010. I can run the site, but as I make changes in the app_code folder classes, they don't seem to commpile and warn me of compile-time errors. As soon as I get to a point that calls the class, the errors show up. Sounds JIT I guess, but this isn't how it was working in 08. Is there an option that was changed in the upgrade process? This is a large project, I really don't want to break something and not find out until some obscure page is opened.
View 1 Replieswhy is it that the exact same codes that i use to create a Windows application, which is able to work, does not work on a Web application? i created a windows application using c# and socket programming language. i will be connected to a remote server and through the windows application, and i will be able to send the "byte[] msg" to the server and activate the LED lightbulbs attached to the remote server. that exact same codes works well on the Windows application. however, when i create another Web application using the same exact codes, i does not have any error yet i am not able to activate the LED lightbulbs attached to it. is it that through the web or internet explorer i am not able to send the "byte[] msg" correctly? or that i sld modify "byte[] msg" to suit the web usage? or any other reasons?
View 7 RepliesWe have deployed an application in iis 6.o. We set cache for 1 hr in that application so that the updated data in the back-end will be visible by the user after 1 hr. If the requested data not available in cache it will fetch from database directly.
Is there any way that I can clear this cache in between 1 hr for some of our testing.
Resetting the website and app pool and deleting temp asp.net files didn't work, I have tested that.
I developed an application locally using the Visual Studio 2008 built-in web server and it is running nice and neat on every single browser. When we deployed it on the IIS6 and open it on IE8, there are rendering issues. The fonts are bigger than the other browsers (which are still nice and neat) and some components just moved around. The generated HTML is the same as the others.
View 2 RepliesI'm trying to deply a 3.5 Net application developed in VS Web Express and built using the asp compiler. This works fine when tested using an eval version of Win 2008 Standard server on a VM. However when installing on a production Win 2008 Standard server it fails with the message can not load assembly as it has not been signed or the signature does not match. How come this works in one and not the other? The live server has symantec AV installed and running? If this the reason? Have a bit of knowledge ( as all devlopers do) of OS's but am totally stumped by this. If I could even replicate it on the development machine would allow me to move forward. Do i need full Vis Studio? Do I need to sign the DLLs?

I know there have been countless posts on these types of problems, and I have read through alot of them as well as doing Google searches, but I have not found anything that applies to my specific situation. If anyone has posted a similar question link me to the post with any appropriate derisive comments . Mods if this is the wrong forum feel free to move the post to the appropriate location.
I am a newbie C# developer. I have been getting my feet wet writing a C# web app for my department. I am using the following system:
Windows 7 Professional Visual Web Developer 2010 Version 10.0.30319.1 .Net framework 4.0.30319. IIS version 7.5.7600.16385 Internet Explorer 8.0.7600.16385CO SQL Server 2008 R2
When I run my application in the VWD debugger everything works fine and looks the way I want it to work. When I deploy to IIS (which is on the same box that I develop on) I start having some issues. Here is a breakdown of the problems I am having:
I have an asp:menu control with orientation set to horizontal. When I initially load the sitre after a deploy the menu displays correctly. But when I go to a different web page in the app the menu switches to vertical and the width of each menu item spans the width of the div that surrounds it. On the same page that causes issues with the asp:menu I also have asp:ComboBox controls that are used to filter information on the page. The combo boxes just look like text boxes. The data that should populate the boxes is not present.
I also have some ajax accordion controls contained in asp:updatepanels, neither of which work. The accordion controls are all expanded, and I cannot collapse them. If I trigger an update the entire page reloads instead of just the specific control.
I do not receive any errors when I browse to the page that causes the problems. It loads just fine everything is just jacked up. Like I said, everything works flawlessly in the VWD debugger. I know the VWD debugger does not use IIS, which makes me think this is an IIS issue, but I do not even know where to start to pinpoint the problem.
I have to design asp.net application which has to work on kiosk system. I don't know anything about the kiosk system .so, whether the asp.net application will work on the kiosk system are not I don't know. So any ideas and any sample examples will be very useful for me to start thanking on those lines.
