I am trying to create a format in UltraWebGrid with GroupBy such as below.

Col1             Col2               Col3          Col4

x1                                          20              30

                      a1                    10             10

                      a2                    10             10

                      a3                    0               10

x2                                          20              30

                      a11                 10             10

                      a21                  10             10

                      a31                    0               10

I am using ViewType as Outlookgroupby. How can I create the cells in the group by row and show the aggregated values for the grouped rows?

regards,

Rajiv.
