Glossary Item Box

The GroupHeader section prints once for every data group defined using the field specified in DataField property.  A GroupHeader section requires a matching GroupFooter section.

Object Model

GroupHeader Class

Syntax

Visual Basic (Declaration) 
Public Class GroupHeader 
   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#Copy Code
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;
}
