範例
下列程式碼範例會建立 Chart,以及會在圖表上按一下滑鼠右鍵時顯示訊息方塊的 BeforeRightClick 事件處理常式。這個範例也會將事件處理常式的 Cancel 參數設定為 true,使圖表不會接收到按滑鼠右鍵的動作。
WithEvents RightClickChart As Microsoft.Office.Tools.Excel.Chart
Private Sub DisallowRightClicks()
Me.Range("A1", "A5").Value2 = 22
Me.Range("B1", "B5").Value2 = 55
RightClickChart = Me.Controls.AddChart(Me.Range("D2", "H12"), _
"RightClickChart")
RightClickChart.SetSourceData(Me.Range("A1", "B5"), _
Excel.XlRowCol.xlColumns)
RightClickChart.ChartType = Excel.XlChartType.xl3DColumn
End Sub
Sub RightClickChart_BeforeRightClick(ByRef Cancel As Boolean) _
Handles RightClickChart.BeforeRightClick
MsgBox("Right-clicking this chart is not allowed.")
Cancel = True
End Sub
private void DisallowRightClicks()
{
this.Range["A1", "A5"].Value2 = 22;
this.Range["B1", "B5"].Value2 = 55;
Microsoft.Office.Tools.Excel.Chart chart1 =
this.Controls.AddChart(this.Range["D2", "H12"],
"chart1");
chart1.SetSourceData(this.Range["A1", "B5"],
Excel.XlRowCol.xlColumns);
chart1.ChartType = Excel.XlChartType.xl3DColumn;
chart1.BeforeRightClick +=
new Excel.ChartEvents_BeforeRightClickEventHandler(
chart1_BeforeRightClick);
}
void chart1_BeforeRightClick(ref bool Cancel)
