シンタックス

Visual Basic

'宣言
 
Public ReadOnly Property Drill As DrillDownAppearance

C#

public DrillDownAppearance Drill {get;}

解説

このプロパティは、Infragistics.UltraChart.Resources.Appearance.DrillDownAppearance を UltraWebChart コントロールに提供します。これにより、開発者はランタイムに UltraWebChart のドリルダウン動作に関連する各プロパティを設定できます（デザインタイム環境でのドリルダウン階層の定義はサポートされていません）。

使用例

Visual Basic

' 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
