hi,
I am Telerik report book using but  Microsoft JScript runtime error: Object expected Here's the first line that is causing the error:

ToolbarImageButton('ReportViewer1_ReportToolbar_HistoryGr_NavigateBack_Button','NavigateBack',false,'NormalButton','DisabledButton','PushButton',false);

 

ToolbarImageButton('ReportViewer1_ReportToolbar_HistoryGr_NavigateForward_Button','NavigateForward',false,'NormalButton','DisabledButton','PushButton',false)

 

I am visual sutudio 2008 using(Running 32-bit, windows XP, i.e 8) ,This is a .net 3.5 web application.
I tried   Telerik Report book  and I still get the error.  Any ideas?

Hello bülent,

Usually this problem happens when the report viewer's javascript files are not loaded correctly. Please, use the suggestions from The styles of the web report viewer's toolbar are messed up KB article to troubleshoot the issue. Let us know if you need further assistance.

Kind regards,
