thank you everyone!

i figured out how to get the first row of a dw group using the GetbandAtPointer() method in the clicked event of the button

String ls_ret
long rownum
ls_ret = dw_1.GetbandAtPointer()
ls_ret= mid(ls_ret, (pos(ls_ret, '~t', 1) + 1), 3)
rownum = long(ls_ret)

I would use the buttonclicked event instead of clicked event.  

The row argument will be the first row for the group

Hi Simone,

It is possible using "DataWindow expressions" to obtain row information related to a specific group or page. One option for first row within a group is:

  1. Create a computed column in the group header, (ex: name = first_row)
  2. Define its expression = GetRow( )
  3. Make it visible so you can verify visually as you write your code
    ​Later hide it if you don't want users to see the value on screen

For further info, see PB Help > DataWindow Reference > DataWindow Expression Functions > Alphabetical list of DataWindow expression functions > GetRow

DataWindow expression functions related to groups: CurrentRow, First, and Last

HTH /Michael
