I have a form that has errors on it.... Not a problem. When trying to view the Forms Designer, VS normally will display the error in a "browser" window and "render" html. My IDE is now only showing the "raw" HTML in the form of a string. I would like to see the "rendered" html.

Hi kmurray,

Why do you think this page is an html page? Microsoft doesn't announce how does the page is made. We don't think VS generate an html file and show it in the VS window. VS should generate that html code dynamically. As most of the web site you have browsed, it is not exactly some html pages on the server, instead, it is dynamically generate and send to your client.

I think the valuable information is in the Error List, you can right click an error item to copy the text. Hope this helps.

Sincerely,
Kira Qian

The problem seems to be associated with IE8, try uninstalling IE8 and see if the problem goes away. (Note: I don't mean the underlying issue with your form, but rather how the error is displayed to you).

I had the exact same thing happen. I was handling a form "core" function (overridden OnMove), and I mistakenly accessed a variable that doesn't exist in a designer. Instead of being given a meaningful error in the designer window, I was presented with raw HTML followed by an unfortunate crash by VS (looked to me like a buffer overrun). The fix in my case was very simple: a check to see if this.DesignMode evaluates to true, and if so, don't perform any further calculations (ironically, I had the line in there before I had done any actual override work code, but I had evaluated a static variable prior to checking for DesignMode - and that was my downfall).

Hope this helps!
