hi

i am using Telerik Q2 2015 to develop report that needs a column which value is cumulated with another column. e.g.

 

column A                         column B

2                                           2

3                                           5

4                                           9

5                                           14

 

I used RunningValue(scope, sum(column A)) function in column B, it does not work as expected even it returns values, but the values is not cumulated, Anyone can give me some clues? thanks

Hello David,

Please test creating a custom aggregate that returns the properly calculated value for a given row group scope, or make the calculation in the data-retrieval method and just display them in the column as a field.
