Hi,

Whenever I encounter this scenario (not just with this one class), I usually use this approach:

• Iterate through the Infragistics collection of data items (Appointments, tasks, etc)
• locate the corresponding business object from my own data model
• assign my business object to the Tag property of the Infragistics data item

Whenever I need to get this additional info, I just cast the Infragistics data item's Tag property into my business object's type and access its properties to do anything I need (populate additional form fields, calculations, etc).
