Hello yin tong,
We have a demo with full source code in C# and VB .NET in our Examples project (it comes with the installation). Please take a look at the Data Binding example of RadScheduler. I think that it will help you a lot, as it demonstrates the following:
2.1 How to bind the RadScheduler control to business objects.
2.2. How to bind the RadScheduler control to a sample data base.
2.3. How to create custom appointments and use the AppointmentFactory.
2.4. How to customize the edit appointments dialog and apply it to RadScheduler.
2.5. How to create and apply the AppointmentMapping information.
2.6. How to manually update your data base, after you have made any modifications in your scheduler.
In addition, I would suggest that you look into the topics of RadScheduler in our online documentation.
Please refer to the following link to start with: http://www.telerik.com/help/winforms/declarative_databinding.html
If you need more information, we will be happy to help you.
