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 more helpful message. Since I had just upgraded my ASP.NET AJAX controls to the latest version yesterday, the local cached version was still the prior version. This is what caused the errors. So here's what I did: Close Visual Studio Navigate to the location of the older Telerik assembly Delete it Open Visual Studio - and everything works! If you don't see a message that shows the path of the problem assembly, try dragging a RadScheduler onto the page to see if that shows the details paths. Edit - 1/23/2012 This problem seemed to p

Another Error Creating Control in the Design View with Object Reference Not Set in Visual Studio 2010 ★★★★★★★★★★★★★★★ May 6, 2010 by Web Development Tools Microsoft // 11 Comments Share 0 0 In a previous blog, Controls State: "Error Creating Control" in the Design View in error creating control Visual Studio 2010, I have discussed about an Error Creating Control issue related to accessing the Session state in the OnInit() method. Since then, I have discovered that the Error Creating Control will also show in the design view if we try to access any object not being instantiated at the design time inside the OnInit() method. For example, in a web application project, in a code-behind file that is adding controls dynamically to a page, similar to what was discussed in the article How To Dynamically Add Controls to a Web Page , we have code that’s accessing an object that is null at the design time as shown below When you switch to the design view, you would see "Error Creating Control– xxx. Object reference not set to an instance of an object”, where xxx is a control on your page. Screen shot of the error is shown below A simple workaround for this issue would be to check if we are in t
