註解

DrillEventArgs 類別包含與 Drill 事件相關的資料。當使用者在報表中擷取細目時，CrystalReportViewer 控制項便會引發 Drill 事件。可以在群組或圖表中擷取細目。在群組樹狀結構中選取項目時也會發生。

範例

下列範例會取得 Drill 事件的詳細資料，並於事件記錄檔中建立新項目。

          Private Sub LogDrillEvent(ByVal source As Object, _
          ByVal e As CrystalDecisions.Windows.Forms.DrillEventArgs) Handles _
          CrystalReportViewer.Drill
          Dim eventLog As New EventLog("event.log")
          Dim eventMsg As String = _
          "Drill event:" & vbCrLf & _
          "IsDrillDown: " & e.IsDrillDown() & vbCrLf & _
          "CurrentGroupLevel: " & e.CurrentGroupLevel & vbCrLf & _
          "NewGroupLevel: " & e.NewGroupLevel & vbCrLf & _
          "CurrentGroupName: " & e.CurrentGroupName & vbCrLf & _
          "NewGroupName: " & e.NewGroupName & vbCrLf & _
          "CurrentGroupPath: " & e.CurrentGroupPath & vbCrLf & _
          "NewGroupPath: " & e.NewGroupPath
          eventLog.WriteEntry(eventMsg)
          e.Handled = False
          End Sub
        

          private void LogDrillEvent(Object source,
          CrystalDecisions.Windows.Forms.DrillEventArgs e)
          {
          System.Diagnostics.EventLog eventLog =
          new System.Diagnostics.EventLog("event.log");
          string eventMsg =
          "Drill event:" + "\n" +
          "IsDrillDown: " + e.IsDrillDown() + "\n" +
          "CurrentGroupLevel: " + e.CurrentGroupLevel + "\n" +
          "NewGroupLevel: " + e.NewGroupLevel + "\n" +
          "CurrentGroupName: " + e.CurrentGroupName + "\n" +
          "NewGroupName: " + e.NewGroupName + "\n" +
          "CurrentGroupPath: " + e.CurrentGroupPath + "\n" +
          "NewGroupPath: " + e.NewGroupPath;
          eventLog.WriteEntry(eventMsg);
          e.Handled = false;
          }
