Use the GroupOn property in a report to specify how to group data in a field or expression by data type. For example, this property lets you group a Date field by month. Read/write Integer.
Syntax
expression.GroupOn
expression A variable that represents a GroupLevel object.
Remarks
The GroupOn property settings available for a field depend on its data type, as the following table shows. For an expression, all the settings are available. The default setting for all data types is Each Value.
| Field data type | Setting | Groups records with | Visual Basic |
|---|---|---|---|
| Text | (Default) Each Value | The same value in the field or expression. | 0 |
| Prefix Characters | The same first n number of characters in the field or expression. | 1 | |
| Date/Time | (Default) Each Value | The same value in the field or expression. | 0 |

| Interval | Values within an interval that you specify. | 9 |
In Visual Basic, you set this property in the Open event procedure of a report.
To set the GroupOn property to a value other than Each Value, you must first set the GroupHeader or GroupFooter property or both to Yes for the selected field or expression.
Example
The following example sets the SortOrder and grouping properties for the first group level in the Products By Category report to create an alphabetical list of products.
Private Sub Report_Open(Cancel As Integer)
' Set SortOrder property to ascending order.
Me.GroupLevel(0).SortOrder = False
' Set GroupOn property.
Me.GroupLevel(0).GroupOn = 1
' Set GroupInterval property to 1.
Me.GroupLevel(0).GroupInterval = 1
' Set KeepTogether property to With First Detail.
Me.GroupLevel(0).KeepTogether = 2
End Sub
