Drill Property

Appearance of the hierarchical Drill Down chart behavior.
Syntax
'Declaration
 
Public ReadOnly Property Drill As DrillDownAppearance
public DrillDownAppearance Drill {get;}
Remarks

This property exposes the Infragistics.UltraChart.Resources.Appearance.DrillDownAppearance to the UltraWebChart control, allowing the developer to set properties related to UltraWebChart's drill down behavior at run-time (defining drill down hierarchies in the design-time environment is unsupported.)

Example
' initialize DrillElement
UltraChart1.Drill.Enabled = True
UltraChart1.Drill.DrillElements = New DrillElement() {New DrillElement}
UltraChart1.Drill.DrillElements(0).DrillDown = New MyDrillDown(UltraChart1)

' ...

Private Sub UltraChart1_ChartDataClicked(ByVal sender As Object, ByVal e As Infragistics.UltraChart.Shared.Events.ChartDataEventArgs) Handles UltraChart1.ChartDataClicked
	Dim childTable As DataTable = chartData.Tables("Child")
	UltraChart1.Drill.DrillElements(0).DrillDown.Drill(e.DataRow, e.DataColumn, ChartType.LineChart, childTable)
End Sub


' ...

    Implements IDrillDown
    Private myChart As UltraChart
    Public Sub New(ByVal chart As UltraChart)
        myChart = chart
    End Sub
    Public Sub Drill(ByVal row As Integer, ByVal column As Integer, ByVal chartType As Infragistics.UltraChart.Shared.Styles.ChartType, ByVal dataSource As Object) Implements Infragistics.UltraChart.Resources.IDrillDown.Drill
        ' implement Drill-Down behavior / initialize child chart
        myChart.ChartType = chartType
        myChart.Drill.Enabled = False
        myChart.Data.DataSource = dataSource
        myChart.Data.IncludeColumn(0, False)
        myChart.Data.IncludeColumn(1, False)
        myChart.Data.DataBind()
    End Sub
End Class
// initialize a DrillElement
