Hello Raj,

You can implement AJAX in this scenario:
http://demos.telerik.com/aspnet-ajax/ajaxmanager/application-scenarios/ajaxify-timer/defaultcs.aspx

And make avail of the OnRequestStart event handler:
http://docs.telerik.com/devtools/aspnet-ajax/controls/ajax/client-side-programming/events/onrequeststart

Within the event you can keep the id of the focused input using a HiddenField:
https://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.hiddenfield%28v=vs.90%29.aspx

And using OnResponseEnd event handler you can set the focus back after the AJAX request initiated by the Timer is complete:
http://docs.telerik.com/devtools/aspnet-ajax/controls/ajax/client-side-programming/events/onresponseend

Hope this helps. I can also prepare a sample RadGrid web site if you prefer.
