I am trying to display total count in a particular column inside a treegrid. I have 4 levels and the number is populated in the 3rd level and it should apply sum function to its parents. But since it has a child, sum function is not working properly. But if I try to remove the 4th level so that I have my count in the last level, then it is working fine. I am using ‘js’ format to bind data into the grid.
