Hello Dhamodharan,

Please try out the following:

function lnkSymptom_clientClick(sender, args)
        {
            var window = $find('<%= rwSymptoms.ClientID %>');
            window.show();
            var grid = $telerik.findControl(window.get_contentElement(), "rgSymptoms");
            grid .get_masterTableView();
            return false;
        }

All the best,
