HELP!! Reading a reccurence rule and showing on a custom radwindow

[Swadesh Brojolall]

Hi:
I need your help and advice.
I am using a radscheduler which I have customized to work with a radwindow for appointments. I am stuck on the part where I need to decrypt the recurrence rule and set the appropriate controls in the radwindow..e.g. if hourly, then set the interval and the range...

Please refer me any thread or materials that I can use.

Thank you!
