Unable to edit appointments constants.js http error 500

Hi there,

When trying to move appointments (drag drop) we are receiving a HTTP 500, looking closely at it, it appears to be having an issue with constants.js:93.

Screenshots attached.

Any help is greatly appreciated.

Thanks Vengatesh ,

I am using Scheduler control in ASP.NET MVC.

Hi Georg, 

Sorry for the inconvenience. 

We have prepared the below sample in ASP.NET MVC with CRUD actions. And we suspect that the reported issue is occurred due to either UpdateData method is not in the project or the arguments mismatch. So kindly try the below sample and revert us for further assistance with this.
