We are looking to create a custom SharePoint web part which displays appointment data on a Scheduler. Ideally we want to return JSON format data from a WCF service and bind this to the Scheduler. We do not need to use insert / update functionality. Having had a look at some examples we're not sure where to go with this. We've looked into Data Providers but again we haven't been able to successfully implement this so far. Any help / step by step examples would be greatly appreciated.
