Dear Mr. Steven,

Grouping and Totals in RDLC Report Viewer in VB.Net

One more thing is that for "total" I use as per the names in Category1 & Category2 as in the example below 

Thanks 

CATEGORY1 CATEGORY2    ITEM   PRICE  QTY
A1          A1-1       1000   12000  10
                  A1-1 TOTAL         10
            A1-2       1001   15000  8
                  A1-2 TOTAL         8
            A1 TOTAL                 18
B2          B2-1       1002   25000  20
                  B2-1 TOTAL         20
            B2-2       1004   30000  25

            B2 TOTAL                 75
