In a section layout, you can display totals and subtotals by modifying the summary fields of a TextBox control. Use the following steps to learn how to add totals and subtotals in a report.

These steps assume that you have already added a Section Report template in a Visual Studio project and connected it to a data source. See Quick Start and Bind Reports to a Data Source for further information.

To calculate and display subtotals in a report

1. Right-click the design surface and select Insert, then Group Header/Footer to add group header and group footer sections to the layout.
2. With the GroupHeader section selected in the Properties Window, set its DataField property to CategoryID. This groups the data on the report according to the set field.
3. From the Report Explorer, drag and drop the following fields onto the corresponding sections of the report.

   • Field Name = CategoryID
     Section = GroupHeader

   • Field Name = ProductName
     Section = Detail

   • Field Name = UnitsInStock
     Section = Detail

   • Field Name = UnitsInStock
     Section = GroupFooter

4. With the UnitsInStock field in the GroupFooter selected, go to the Properties Window and set the following:
   • SummaryFunc: Sum
   • SummaryType: Sub Total
   • SummaryRunning: Group
   • SummaryGroup: GroupHeader1
5. Go to the Preview tab to view the report and see the Sub Total appear below each group of data similar to the following image.
