  Hi,
  
  There is a way to get Group Row item value from detail row?
  
  Following custom aggregation example on demo site , thru grid formatitem handler, we can check if that is stay in group row and easily to get group value.
  
  but, if cell is not in group rows (-means detail row) , can we get the group row object which cell is belongs to?
  
  For example , how can caculate ColC valule below
  
  by exp ColC = ColB/Sum(colB)
  
  
  
  ColA ColB ColC
  
  AAA 7 7/7
  
  1 1/7
  
  2 2/7
  
  4 4/7
  
  BBB 5 5/5
  
  5 3/5
  
  2 2/5

  Hi,

  To get the current group of a data item, you may use the groups property of the CollectionView class. This property is an array that contains all of the groups created. Please refer to the sample link below for reference:

  Let me know if this was your requirement.
