How to show total in page wise for .rdlc

Hi,

  I want to add total page wise in table control. I'm able to add the total in report footer.

1. Use a table control to hold fields. For example: Sales fields whose textbox's name is "Sales".

2. Added the report footer to the report. And drag a textbox into it.

3. Set the expression of that textbox with "=sum(ReportItems!Sales.Value)".

But unable to add page wise total in the table control bottom eg:If sales has total records of a particular page only that total should display.It has to  repeat for all pages..

SrNo.     Sales

1            200
2            200
3            200
4            200
5            200
6           100
7           100
Page1 Total = 1200

10        300
