How to reset the record number on change of a group?

Dear experts,

In my crystal report, I want to display the reocrd number of each group. like the following:

Group I:
Item             Name
   1                  A
   2                  B

Group II:
 Item             Name
   1                   C
   2                   D

Currently, I am using VB.Net to develop the report and the records are in one dataset. My problem is I cannot reset the record number when there is a group change. In what way may I acheive this? Thank for any help!!

In CR8.0 I would do the following:

Create a Running Total Filed, in which the Summary does a Count of (for example) your Name field, Evaluate for each record, and Reset on change of group.
