Hi Jeffrey,

Thank you for contacting the Telerik team.

To achieve the described scenario, you could subscribe to the OnSelectedIndexChanged event of the Clinic combo (custom resource), where the start/end date could be changed.

I have prepared a sample web page, which contains a simple workaround for this scenario. You could download the attached files, and test it locally.

The sample page contains a RadScheduler which has an OnClientFormCreated event subscribed to it. In this event the Start Date/Time and End Date/Time objects are found and saved in global variables. Also, an  OnClientSelectedIndexChanged event is subscribed to the Clinic combo, and values are set to the start/end date/time objects (saved in the global variables), in accordance with the Combo's selected item's text. (Take a look at the attached sample, to see how it is implemented.)

I hope you will find this useful for your scenario.

Please feel free to contact us if you have further questions.

Kind regards,
Ivana
the Telerik team
