Dataset and Balloon property

Hi,
In my program, I'm using LinkData to create a PushPin dataset.
I was wondering how I could programmatically set which Balloon field is displayed.

so far i've tried
objDataSet.Fields.get_Item(ref index).VisibleInBalloon
but i can't seem to be able to set the value...

Take a look at the MapPoint help doc for the method
DataSet.SetFieldsVisibleInBalloon(arrayOfFields)

Cool! Thanks!
