external calender ton control scheduler

I use kendo calender instead of minicalender in scheduler.How can I control scheduler dates with kendo calender used in this link
demos.kendoui.com/web/calendar/index.html

You can create custom time section for lightbox and use any components in it.
If you want to change the current date of scheduler - you can call scheduler.setCurrentView API

I mean to use minicalender externally to control scheduler as a whole.

You place kendo calendar somethere on the page and from its date-click-handler call scheduler.setCurrentView(date) - which will force scheduler to show the define date.
