Answer 1

RDLCs have a RowNumber("ScopeName") Function. This will return the row number of the record within the given scope.

You can see the existing groups for the report below the designer under a "Row Groups" and "Column Groups" headers. Select the column inside the grouping where you want the row number and view the Row Columns, The default names will be:

[(Group1)
 ≡(Details1)

Set the expression for the Row Number column to be

=RowNumber("Group1")

Answer 2

Right Click on your Report property then go to code then paste the code below

   Dim private count as integer = 0
   Dim private iniRow as integer = 0
   Dim private iniGrp as Object = ""
   Public function MatrixRow(Byval rowNum as integer,Byval rowGrp as Object) as integer

   if iniGrp = "" then
      iniGrp = rowGrp 
   end if

  if rowGrp <> iniGrp then
      iniRow = 0 
      count = 0 
      iniGrp = rowGrp 
  end if

  if iniRow = 0 then
      iniRow = rowNum
  end if

  if rowNum = iniRow then
     count = 0
  end if

   count = count + 1
   Return count
  End function

then use this function like

   =Code.MatrixRow(RowNumber(Nothing),(YourgroupfiledNameFromDataest))
