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:

    Visual Basic  Copy Code 
    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.

      Copy Code 
    =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.

      Copy Code 
    =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.
