How to: Reset Report Page Numbers

On some reports, you may want to group sets of data together and reset the page number after each group. For example, in the CRONUS International Ltd. demonstration database, report 206, Sales Invoice, displays sales invoices that are grouped by sales invoice number. To reset the page number to 1 for each group of data, you must modify code on the client report definition (RDLC) report layout.

To reset page numbers

  1. In the development environment, on the Tools menu, choose Object Designer.

  2. In Object Designer, choose Report, select a report that you want to modify, and then choose the Design button.

  3. On the View menu, choose Layout.

  4. In Microsoft Visual Studio, in the Report.rdlc file, on the Report menu, select Report Properties.

  5. In the Report Properties window, select the Code tab.

  6. Add the following code in the Custom code text box:

    REM Reset Page Number:  
    
        Shared offset As Integer  
        Shared newPage As Object  
        Shared currentgroup1 As Object  
        Shared currentgroup2 As Object  
        Shared currentgroup3 As Object  
    
        Public Function GetGroupPageNumber(ByVal NewPage As Boolean, ByVal pagenumber As Integer) As Object  
            If NewPage Then  
                offset = pagenumber - 1  
            End If  
            Return pagenumber - offset  
        End Function  
    
        Public Function IsNewPage(ByVal group1 As Object, ByVal group2 As Object, ByVal group3 As Object) As Boolean  
            newPage = False  
            If Not (group1 = currentgroup1) Then  
                newPage = True  
                currentgroup1 = group1  
                currentgroup2 = group2  
                currentgroup3 = group3  
            Else  
                If Not (group2 = currentgroup2) Then  
                    newPage = True  
                    currentgroup2 = group2  
                    currentgroup3 = group3  
                Else  
                    If Not (group3 = currentgroup3) Then  
                        newPage = True  
                        currentgroup3 = group3  
                    End If  
                End If  
            End If  
            Return newPage  
        End Function  
    

    Note

    This code is also available in report 206, Sales Invoice.

  7. Choose the OK button.

  8. In Visual Studio, in the Report.rdlc file, create a hidden text box in the data region that contains the data on which you have a group. For example, create a hidden text box on the table or list that contains the sales invoice number. For more information, see How to: Add and Identify Hidden Fields.

  9. Right-click the text box, and then choose Text Box Properties. In the Properties window, on the General tab, set the name of the text box to NewPage.

  10. In the Properties window, on the General tab, enter the following code in the Value field.

    =Code.IsNewPage(Fields!<grouping field1>[,<grouping field2>,<grouping field3>])  
    

    For example, if you are grouping by document type, then grouping field1 is Fields!Document_Type.Value.

    Note

    If you want to use more than three groupings, you can modify the code in the IsNewPage function. If you want to use fewer than three groupings, you can either modify the code in the IsNewPage function or use a static value for one or more of the parameters when you call the IsNewPage function.

  11. In the Text Box Properties window, choose the OK button.

  12. In Visual Studio, in the Report.rdlc file, right-click the text box in the header that displays the page number, and then select Expression.

  13. In the Expression window, enter the following expression.

    =Code.GetGroupPageNumber(ReportItems!NewPage.Value,Globals!PageNumber)  
    

    The ReportItems!NewPage.Value parameter is the value of the NewPage text box, which you created in step 8.

  14. In the Expression window, choose the OK button.
