Hi,
what is the difference between the index and the key in a ListDataSource?
In the Custome Data Source Sample program, the 'key' is used to swap, deleter, remove elements of the data source, instead of the index, why?
Hi Mesarina,
A key is used to uniquely identify the item in the data source. It would not change, even if the item was moved to a different location in the list. The index would indicate the location of the object in the list.
This talk actually explains the concept quite well: http://channel9.msdn.com/events/BUILD/BUILD2011/APP-210T He talks about keys and index early in the talk.
