And I found a solution that worked for me, but it might not be readily available to fix for everyone, I'll explain. I've attached two screenshots, a before and after that displays my Visual Studio 2010 Design Views with the errors and the fixed result. The part that helped me figure it out was with the RadScheduler. It displayed a much more helpful message that helped me find the solution. If you notice in the "error" screen shot the RadTreeView and RadMenu controls do not display anything but the error message. But when I dragged a RadScheduler on the page, it displayed amuch

There's plenty to google on this and I've tried it all. What am I missing? -Trying to debug from another instance of Visual Studio: Error Creating Control vs2010 MasterPage - there's not a whole lot of detail on how this is supposed to work. I error creating control started another empty instance of VS2010 and attached to devenv.exe. Set Debug->Break All. Switched to design mode in the website instance of VS. Ran the website instance of VS in debug mode. Nothing happens. I was hoping this could help because I DO have some user controls in the page. I can't find anything wrong with them though. Can I get more detail on how exactly to do this type of debugging? See the end of this post for the .aspx source. -Commented out some <% =Session["Username"]%> junk in the tag of the page, since apparently accessing session stuff could cause this -Checked the OnInit() method for dynamically adding controls or accessing uninstantiated objects.

Tweets by @RickStrahl Error Creating Control Errors in the ASP.NET Designer February 16, 2009 - from Maui, Hawaii 18 comments Tweet I’ve been getting a lot of Error Creating Control in the designer recently. Well, probably recently only because I’ve been using the designer a bit over the last couple of days to build some data entry heavy pages that use my DataBinder control, which is a lot easier to set up using the designer than in markup since it’s an extender control. But more than a few times in the last few days Visual Studio had decided to mangle my control with an error like this: It looks like somehow Visual Studio is failing to properly sync the files in the BIN directory (which are not actually used in the designer) and the temporary copy of the assemblies that simulates the ASP.NET temporary assembly directory. How these files can get out of sync or how they even can be differentiated is something I don’t understand. I’ve been trying to pinpoint what causes the problem and it seems (although I can’t duplicate it 100%) that when the underlying control assembly changes these errors start popping up in the designer. In this particular project I am using controls in my own Web Control project and since I’m working on the library at the moment this control assembly gets recompiled occasionally. Every time a change is made it seems like Visual Studio screws this up. The resolution? Restart Visual Studio which cleans out the temporary assembly folder. When I come back in and re-open the page everything is as it should be. It seems this behavior is something new though – I’ve done heavy control development and never really noticed issues with this until Visual Studio 2008 released possibly even as late as SP1. In the past I’ve always been able to use the designer’s Ref
