   Inherits Section

[C#]
public class GroupHeader : Section

Remarks

Since ActiveReports does not sort the data before grouping it, your data source should be sorted on all the data fields that you have specified in group header sections. For example, for a report to properly create two groups on Country and City data fields you must sort the data by those data fields in the specified order. If your data is not sorted you end up with the same group appearing multiple times in the report at different locations (i.e. the report is NOT grouped).

Example

[C#]

private void GroupHeader1_Format(object sender, System.EventArgs eArgs) 
{ 
    this.GroupHeader1.ColumnLayout = true; 
    this.GroupHeader1.DataField = "Country"; 
    this.GroupHeader1.GroupKeepTogether = GroupKeepTogether.None; 
    this.GroupHeader1.KeepTogether = true; 
    this.GroupHeader1.NewColumn = NewColumn.None; 
    this.GroupHeader1.NewPage = NewPage.None; 
    this.GroupHeader1.RepeatStyle =  RepeatStyle.None; 
    this.GroupHeader1.UnderlayNext = true; 
}

[Visual Basic]

Private Sub GroupHeader1_Format(ByVal sender As Object, ByVal e As System.EventArgs) Handles GroupHeader1.Format

   Me.GroupHeader1.ColumnLayout = True

   Me.GroupHeader1.DataField = "Country"

   Me.GroupHeader1.GroupKeepTogether = GroupKeepTogether.None

   Me.GroupHeader1.KeepTogether = True

   Me.GroupHeader1.NewColumn = NewColumn.None

   Me.GroupHeader1.NewPage = NewPage.None

   Me.GroupHeader1.RepeatStyle = RepeatStyle.None

   Me.GroupHeader1.UnderlayNext = True

End Sub
