DataField Property (GroupHeader)
Example 

GrapeCity.ActiveReports.v11 Assembly > GrapeCity.ActiveReports.SectionReportModel Namespace > GroupHeader Class : DataField Property

Gets or sets the name of the field used to group the data source records.

Syntax
'Declaration
 
Public Property DataField As String
public string DataField {get; set;}

Property Value

A string value that represents the name of the field to be grouped.
Remarks

ActiveReports checks for any changes in the value of the specified field and starts a new group when the value changes. Current groups are ended (i.e. the group footer section is printed) before the new group is started.

The specified field can originate from the data source or an unbound field added to the Fields collection in the DataInitialize event.

Example
private void rptSection_ReportStart(object sender, System.EventArgs eArgs)
{    
  this.groupHeader1.DataField = "Country";
}
Private Sub rptSection_ReportStart(ByVal sender As Object, ByVal e As System.EventArgs)   
 Me.GroupHeader1.DataField = "Country"
End Sub
