telerik:RadScheduler -- Exception: 13.333333015441895 is not a valid value for Int32

[Vamsi]

Hi, This is little bit weird and hard to debug. only one user (rest of the 10 business users are not having this issue on their computers, and all users are having similar systems and applications and all are using latest chrome browser only) is getting below error when trying to open advanceedittemplate in telerik:RadScheduler by clicking on any event on the calendar control. we are using 2012 version telerik.web.UI.dll.

tried to put try catch block in all the events but it logs below error only. and more over I'm not able to replicate this issue on the development machine using Visual Studio 2012.

Hello Vamsi,

The issue should be resolved in the latest versions of the control so an upgrade is highly recommended. 

In the meantime, you can try placing the following script somewhere under the ScriptManager of the page:

Telerik.Web.UI.RadScheduler.prototype.saveClientState =  function() {
        return '{"scrollTop":' + Math.round(this._scrollTop) + ',"scrollLeft":' + Math.round(this._scrollLeft) + ',"isDirty":' + this._isDirty + '}';
    }

Regards,
