I need to be able to move/resize a recurring apointment such that any changes are reflected in any future linked appointments. At the moment I can't seem to resize even the master appointment of a recurring series. Please advise.
Currently, such scenario is not supported by RadScheduler. I have logged it in our Public Issue Tracking System as a feature request and we will address it in a future release. You can subscribe to the PITS item to track its progress and you can vote for it in order to increase its priority.
For the time being, you can create a custom implementation of this functionality by inheriting from RadScheduler. Please refer to the attached project for additional details.
Your Telerik points have been updated for the feature request.
I hope this is helpful. Do not hesitate to write back in case you have any additional questions.
