Hi,

I would like to know the best way to validate the user's input in the Advanced Edit/Input form.  I want to ensure that the start date is before the selected end date for the appointment.  I would also like to ensure that any text boxes that contain recurrence information contain a valid integer value.  I noticed that when the user enters some text in one of these fields the server returns an error. 

Thanks,
-Paul

Hello Paul,

Thank you for the suggestion. This is a very good idea indeed. We will consider preparing an example using the advanced form to show a way to implement the desired functionality.



All the best,

Any update on this? I'd like to validate that the end date is after the start date as well. Any recommended techniques would be appreciated.

Hi Trevor,

The current version of RadScheduler does not feature integrated validation controls. You can perform basic validation in the AppointmentInsert and AppointmentUpdate events and cancel them if the data is not acceptable. But this does not help with the exceptions that are thrown when, for example, a user enters an invalid number in a numeric field. We have addressed these shortcomings and the Q3 release will handle user input much better and will include validator controls. Until then, the best alternative is to use custom advanced form templates and implement validation in them. We will also update the provided sample templates for the Q3 release, but at the moment we can only provide you rough working versions, if you decide to go this route.

I hope this helps.
