To fix it replace

ToolPanelView="None"
so your html code looks like

<cr:crystalreportviewer id="CrystalReportViewer1"  ToolPanelView="None"></cr:crystalreportviewer>

Error Message - Microsoft JScript runtime error: 'bobj' is undefined

I was getting this error message after upgrading crystal report to version 13
to fix it
- I noticed that if I run the same code in Mozilla I am not getting this error. 



So my first step was to delete temp files in IE, but it didn't resolve my issue.  Next I changed my default browser to mozilla, then I ran my site from visual studio - no error was produced.  Then I changed my default browser back to IE and everything was fine... for while.  After moving the following folder aspnet_client to application root directory - problem disappeared.
