Description Greg Martin 2015-01-08 00:56:47 UTC
When following the recommended method for not having RowHeight also affect the Group Header height of using HasUnevenRows the performance of ListView takes a major hit (my list is only 3,000 items long).

My Recommended solution would be to match the iOS pattern of being able to specify a separate default header height from the default row height and by implementing that same mechanism under the hood, will eliminate the performance issue likely related to calculating the list height.
