Hi,

I think you may have to do this manually using code. Create an integer variable to count to rows and a 'Last Ser no' variable as a string.
At the start of the report call a function to initialise the row counter and the serial no variable.
In the matrix, add a column and insert a call similar to:

=Code.GetRowNo(Fields!SerNo)

The function GetRowNo will be something like:

Public Function GetRowNo(byval SerNo as String) as Integer

if SerNo <> lastSerNo then
rowCount = rowCount + 1
LastSerNo = SerNo
End If
Return rowCount
End Function

This works in a test scenario.

Hi,

It sounds as though the report is being rerun in some way when you render it again. I can't recreate this problem in 2008.
What code do you have in your initialisation function, and where are you calling the initialisation function from?

Hi Tim,

Please find attachment of report. This report is in excel. But when this same report is display in Pdf, the sr. No. Column is start from 71. I am attaching .pdf fiilr screen shot also.
In design time I am using function that sent by you.

public dim LastSerNo as String
public dim rowCount as int32 = 0

Public Function GetRowNo(byval SerNo as String) as Integer

if SerNo <> lastSerNo then
rowCount = rowCount + 1
LastSerNo = SerNo
End If
Return rowCount
End Function

and in textbox exppression of matrix 1st column 2nd row is =Code.GetRowNo(Fields!StudentRegCode.Value)

Ok, you don't seem to have a initialise function to reset the count.
Do the following:

Insert an additional function Initialise:

Public Function Initialise()
rowCount = 0
LastSerNo = ""
End Function

and then add a textbox to your report  - above the main table so it is executed first - with the expression = Code.Initialise(). This textbox can be hidden.

Then each time the report is rendered the variables should be reset.
