Hi Sivaprakas Subramanian,
Thank you for writing.
1. We have such an example in the Examples application that comes with our suite, section Scheduler >> Databinding
2. The above example demonstrates how to map the RadScheduler to the MSAccess database.
3. You can create a new custom form that inherits EditAppointmentDialog. After that you can change the behavior of each control that belongs to the this form. The next step is to replace the form and you can read how to do it here
4. After you create a custom form, you can override the method ApplySettingsToEvent and update the database after calling the base method.
In regards to the SQL database mapping, you watch the this webinar
All the best,
the Telerik team
