Designer file not updating visual studio 2008

Here's how to do it:. Go to the ascx. Save and do build and the you should be good to go. However when you do this, it usually pops up with the error, as to why it didn't auto-regen in the first place, its usually a control ref that isn't declared in the head of the page.

Most cases can be solved by editing the ID of a server control just add a character, then delete it. And yes, there are cases where you need to do the delete-the-file magic listed above - but the name-change solution will work most of the time.

My experience is that if you want to do like in this article, like stated above. I blogged about it here. I've found a way to solve this problem without changing any code or running commands like "Convert to Web Application" - and it's simple too! What I found was that restarting Visual Studio often solves the problem, but sometimes it doesn't. In those cases, if you close Visual Studio and then delete all content in the "obj" directory for the web project before you open it again, it has always worked for me.

If you edit an ASPX page while debugging, then the codebehind doesn't get updated with the new classes. So, you have to stop debugging, trivially edit the ASPX page like add a button or something , then click Design View, then delete the button. Then, your designer files should be updated. If you are using VS or later , make sure that the code referenced with attribute "CodeBehind" not "CodeFile", then do below steps.

Here is wat i experienced , Select the website folder right click in the Solution Explorer, select Convert to Web application for all the aspx file a designer file will get generated. I've encountered the same problem for years now, working in Visual Studio And I've tried every "solution" on StackOverflow and dozens of blogs, just like I'm sure all of you have.

And sometimes they work, and sometimes they don't, just like I'm sure all of you have encountered. And apparently it's still an issue in VS and VS So finally, a couple of months ago, I decided enough was enough, and over a few weeks I built a tool called "Redesigner" that generates. It's open-source under the BSD license , with the source code available on SourceForge — free to use, free to steal, free to do anything you please with.

And it does what Visual Studio fails to do so often, which is generate. It's a stand-alone command-line tool that parses. It does all the parsing and reflection itself to avoid relying on existing code, which we all know too well is broken.

It's written in C against. NET 3. Web for anything other than type declarations, and it doesn't use or rely on Visual Studio at all. Redesigner can generate new. Exception was thrown. We've been using it at my workplace to get us out of jams for the better part of the last month now, and while Redesigner is still a beta, it's getting far enough along that it's worth sharing its existence with the public. I soon intend to create a Visual Studio plugin for it so you can simply right-click to verify or regenerate designer files the way you always wished you could.

But in the interim, the command-line usage is pretty easy and will save you a lot of headaches. Anyway, go download a copy of Redesigner now and stop pulling out your hair.

You won't always need it, but when you do, you'll be glad you have it! Your designer file should be regenerated. I was trying to do this on a Sharepoint project, using VS and TFS , and none of the solutions above worked for me. Primarily, the option, "Convert to Web Application" is missing from the right-click menu of the. This answer helped finally. My class looked like this:. I first changed the Inherits to MyProjects. Pages , hit Save, then changed it back to MyProjects.

FinanceSubmission and hit Save again. And wallah! The designer page was regenerated! How to generate aspx. It will generate all the designer files again. Delete the designer. If there is a problem with your control declarations, such as a tag not being well-formed, you will get an error message and you will need to correct the malformed tag before visual studio can successfully re-generate your designer file.

I had two problems I had the problem that my new controls would not generate in the designer file when declared in the. The problem was that i declared them in the code behind also. So deleting the declaration in the code behind solved my problem. If you are like me and you add old. ASPX files to a more recent project. You are probably going to forget some of the controls used on the page.

Next, if you have Designer files, delete all of the inserted - designer files. Next, make sure there are not any other errors when you compile, other than the designer files. Finally right click your web project and click on Convert to Web Application.

This will insert the designer files you need. One thing that nobody's mentioned is to visit the page. Ask a question. Quick access. Search related threads. Remove From My Forums. Asked by:.
