Hello Jesse Lawler,
We are planning to update the demo for RadScheduler External Edit in RadDock
(by adding reminders and recurrences).
Meantime please take a look at the project in the attached .zip file. It is made to work with latest Q3 Release (2010. 1 1109)
but you can use it as example for your custom advanced form.
Please let me know if you have more questions.
