Designer file not updating asp net

Supposedly this should also fix up ids and check there are no duplicates and most of the time it does, but as in this case apparently it fails to check existing controls on the page when generating new ids. You have a web user control which has an error in the html markup like the one above.The user control tag becomes the focus of the error after pasting it onto the parent page, rather then the real problem, because yet again, the designer reference has not been created.As to the duplicate ID problem that is usually the cause of problems for me when cutting and pasting, that is also controllable via configuration option in the Visual Studio options. I know, duh, but the error list did not show it and the control i was pasting or typing in new onto the form was the focus of the error because Visual Studio refused to create a designer code file reference.This option when checked adds ids to any server controls that get pasted without them. Fixed problem by removing or setting onclick property.2.If there’s a problem in your codebehind with controls not showing up as above the problem usually is that the designer file is empty (if the page was created new with an error) or not updated again.The most common scenario for me is when I paste code in from another page.In my testing most of the time the more helpful error message will come up eventually.All of this also applies to full site WAP conversions.

This seems to be a problem with Visual Studio and my knowledge is not advanced enough to pick it. Net Web Application project, then there are chances that you have to face a problem, where the for the wep page stop auto upadating as you add the new controls to the page. Once I fixed that typo, the started updating correctly.When this happens, it’s really frustrating as you don’t get the error on why it’s not being auto updated. However today was a bad day (that 1% time), where the above solution didn’t worked. Net server tags (have to remove couple of those too), and finally found the issue. But what was frustrating that there was no error for this, instead the just stopped auto updating after that control.Or hopefully you get a more useful error message like this one: which gives you an idea what the problem is.It’d be really nice if the designer/markup editor could throw this or a similar dialog up for you when it can’t create the .designer file, natch – it requires the explicit Convert To Web Application option after you’ve nuked the designer file.
