Hi,

We've implemented RADSchedular control for our application. Scheduler control running properly in every browser except Internet Explorer 10 (IE 10).
In case of IE 10
1. Scheduler layout is not showing properly. (Please see the attached image - Schedular_IE_10.png)
2. Right click event is now working.

Whereas in Chrome it shows the proper layout. (Schedular_In_Chrome.png)

We've make some changes according to these instructions -

http://www.hanselman.com/blog/BugAndFixASPNETFailsToDetectIE10CausingDoPostBackIsUndefinedJavaScriptErrorOrMaintainFF5ScrollbarPosition.aspx

We've followed "SITE-ONLY FIXES", but we are unable to solve the issue.

Development Environment
.NET Framework - 4.0.
Windows 7.
Visual Studio 2010.
Telerik.Web.UI - 2012.1.411.40
Telerik.Web.UI.Skins - 2012.1.411.40

Thanks in advance for your valuable inputs.

Thanking you.

Best Regards,

Hello Pratap,

It seems that this is a known issue with our RadScheduler control and a css workaround posted in our Misalignment section located here might avoid that unusual behavior . Please take a look at the second common problem "In Browser Mode Compatibility IE9 the time slots of the RadScheduler twist to the left" and the solution below the image. It is quite possible that the right click is not working because the time slots are twisted to the left and you are actually not clicking on a time slot.

Hi Boyan Dimitrov ,

Thank you very much for your suggestion.

We've updated the CSS and deployed it in two servers.

1. Test Server
In Test server RadScheduler  running well.
2. Live Server or Production Server
In production server the problem still exists. Unable to identify the exact problem.

From console (developer tool) it’s showing
“Unable to get property 'PageRequestManager' of undefined or null reference Telerik.Web.UI.WebResource.axd”

If I run this application in Browser Mode: IE9 then it’s running well.

Attached image is console error.

Could you be please tell me where is the problem? Thanks in advance for your valuable inputs.

Best Regards,
Pratap

Hello,

Thank you for getting back to us.

It seems that the issue is related to the problem described in the following post. At the bottom of the post you may find an attached sample project. Could you please try to run that  project on your production server and let us know how that worked? This might help us to determine whether the issue is caused by not correctly loaded Microsoft scripts or it is related to our RadScheduler control. Please share any JavaScript errors that you might have running the attached sample project on the production server.
