Data Type

Description

ReportName

String

the name of the report that will contain the new group level.

Expression

Required

String

The field or expression to sort or group on.

Header

Required

Integer

Indicates a field or expression will have an associated group header. If the header argument is True (–1), the field or expression will have a group header. If the header argument is False (0), the field or expression won't. You can create a header by setting the argument to True.

Footer

Required

Indicates a field or expression will have an associated group footer. If the footer argument is True (–1), the field or expression will have a group footer. If the footer argument is False (0), the field or expression won't. You can create a footer by setting the argument to True.

Return Value

Long

For example, suppose you are building a custom wizard that provides the user with a choice of fields on which to group data when designing a report. Call the CreateGroupLevel method from your wizard to create the appropriate groups according to the user's choice.

You can use the CreateGroupLevel method when designing a wizard that creates a report with groups or totals. The CreateGroupLevel method groups or sorts data on the specified field or expression and creates a header and/or footer for the group level.

The CreateGroupLevel method is available only in report Design view.

Microsoft Access uses an array, the GroupLevel property array, to keep track of the group levels created for a report. The CreateGroupLevel method adds a new group level to the array, based on the expression argument. The CreateGroupLevel method then returns an index value that represents the new group level's position in the array. The first field or expression you sort or group on is level 0, the second is level 1, and so on. You can have up to ten group levels in a report (0 to 9).

When you specify that either the header or footer argument, or both, is True, the GroupHeader and GroupFooter properties in a report are set to Yes, and a header and/or footer is created for the group level.

Once a header or footer is created, you can set other GroupLevel properties: GroupOn , GroupInterval , and KeepTogether.

Note Note

If your wizard creates group levels in a new or existing report, it must open the report in Design view.

The following example creates a group level on an OrderDate field on a report called OrderReport. The report on which the group level is to be created must be open in Design view. Since the header and footer arguments are set to True (–1), the method creates both the header and footer for the group level. The header and footer are then sized.

Sub CreateGL() 
 Dim varGroupLevel As Variant 
 
 ' Create new group level on OrderDate field. 
 varGroupLevel = CreateGroupLevel("OrderReport", "OrderDate", _ 
 True, True) 
 ' Set height of header/footer sections. 
 Reports!OrderReport.Section(acGroupLevel1Header).Height = 400 
 Reports!OrderReport.Section(acGroupLevel1Footer).Height = 400 
End Sub
