Motion control applications with large, moving loads can generate more energy during deceleration than the drive can safely dissipate internally. In such cases, a passive regeneration resistor, such as the MC4U-REGEN-600, can connect to the drive to dissipate the excess energy.
Sometimes when I'm editing page or control the .designer files stop being updated with the new controls I'm putting on the page. I'm not sure what's causing this to happen, but I'm wondering if there's any way of forcing Visual Studio to regenerate the .designer file. I'm using Visual Studio 2008
In VS2013-15 there is a Convert to Web Application command under the Project menu. Prior to VS2013 this option was available in the right-click context menu for as(c/p)x files. When this is done you should see that you now have a *.Designer.cs file available and your controls within the Design HTML will be available for your control.
Well I found a solution that works, though I don't really like it. I had to delete the .designer.cs file then recreate an empty file with the same name. When I went back in and saved the aspx file again, the designer file was re-generated.
As it turns out, VS doesn't modify the designer file for a page that uses CodeFile (run off of pages) instead of CodeBehind (DLL). This is true no matter how many times you close VS, reload the project, re-create the control(s), or modify a file. Nothing would prompt VS to regenerate the designer. It's as if it doesn't create the designer file for CodeFile pages but does require it to be there.
I changed it to CodeBehind and saved the page. The designer file updated immediately. Then I just changed it back and everything was still golden. This behavior seems to be new with VS 2010 / .NET 4.0 as VS 2008 by default didn't suffer from this.
If you switch to Design View, it will show the control as unable to be rendered. Fixing the control (in my case it was an extra quote in the properties) and recompiling should regenerate the designer.
Most of the solutions here don't work if you're running Visual Studio 2013 and possibly 2012. Microsoft probably introduced some optimizations to make the IDE snappier, consequently they've reduced the number of cases that trigger the code generator. The following scenarios that used to work no longer do:
The solution is surprisingly simple, but it's slightly cumbersome. In order to trigger the code generator, change something that would require the designer.aspx.cs to be generated. Changing content that doesn't affect code, such as a CSS style or adding text, won't trigger the code generator. You must change a referenced control. Here's how to do it:
the only way I know is to delete the designer file, and do a convert to web app. 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.
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.
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.
Just to add to the long list of answers here - I've just run into this issue in VS2010 (SP1) with an .aspx file. I tried adding and removing standard ASP controls (which has worked in the past) but in the end, I had to remove one of the runat=server lines from an existing control (and save) to force the designer file to regenerate.
I've encountered the same problem for years now, working in Visual Studio 2008. 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 VS2010 and VS2012.
It's a stand-alone command-line tool that parses .aspx and .ascx files, performs all the necessary reflection magic, and spits out correct .designer files. 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 3.5, but it makes pains to avoid using even System.Web for anything other than type declarations, and it doesn't use or rely on Visual Studio at all.
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.
I was trying to do this on a Sharepoint 2010 project, using VS 2010 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 .ASPX file when using TFS in VS 2010.
I first changed the Inherits to MyProjects.Finance.Pages, hit Save, then changed it back to MyProjects.Finance.Pages.FinanceSubmission and hit Save again. And wallah! The designer page was regenerated!
Delete the designer.cs file and then right click on the .aspx file and choose "Convert To Web Application". 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 the problem that my new controls would not generate in the designer file when declared in the .ascx file. The problem was that i declared them in the code behind also. So deleting the declaration in the code behind solved my problem.
