Different snap behavior for appointments

[Christian Burkhardt]

Hi,

I need to change the snap behavior depending on the appointment properties. For example, if an appointment (custom) has a property Planned, I know that this appointment was already been planned and the user should be able to drop the assignment on a different resource but at the same time interval.

I can do the snap easily for all appointments  by using a custom SnapBehaviour which inherits from DefaultSnapBehavior, but I can't find a way to modify the snap behaviour depending on the appointment properties. The problem I have is that I can't get the appointment in the SnapBehaviour class.

Is there any way in which I can do this?

Thanks

Hi Christian ,

At this stage I cannot suggest you a way to implement the task by using the SnapBehaviour. You can try complete the task by using a custom Drad Drop behavior and override the Drop method.

Hi Rosi,

I have the same problem as  Christian.
So I'm trying to override the Drop method, but is it possible to raise the AppointmentCreated event from within my own drop method?

Hi,

Any news about this in q2 2011? Is there a way to define snapping during a drag&drop operation from an external source, depending on some values on the dragged data?

Thanks!

The snap behavior still cannot access the appointments' properties in order to provide different snap logic for the different appointments.

Hmm...I was just playing with it. What I did in a behavior that inherits from DefaultSnapBehavior was to overwrite SnapStart and SnapEnd and there, in the SnapData parameter you can get the OriginalData, which looks to be actually the original Appointment (or derived class), or in case of a drag&drop the Occurrence instance (from which you can get the Appointment). So if I cast it appropriately I can get to its data and return a snap date appropriately.

This seems to work, am I doing something wrong? :)

Hi Adrian,

You are correct, the OriginalData property sometimes contains the appointment that is being snapped (when resizing the OriginalData is not the appointment), but I should warn you that this might change in the future versions of the control.

Hi Valeri,

Thanks for the answer. Hopefully if it changes in the future, it will be for the better :)
