Chart.SelectEvent Event


Occurs when the Chart control is selected.

public event Microsoft.Office.Interop.Excel.ChartEvents_SelectEventHandler SelectEvent;


The following code example creates a Chart with a handler for the SelectEvent event that displays a message box when the primary axis of the chart is selected.

private void DisplayWhenPrimaryAxisSelected()
    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.SetSourceData(this.Range["A1", "B5"], 
    chart1.ChartType = Excel.XlChartType.xl3DColumn;

    chart1.SelectEvent +=
        new Excel.ChartEvents_SelectEventHandler(

void chart1_SelectEvent(int ElementID, int Arg1, int Arg2)
    if (Excel.XlChartItem.xlAxis == (Excel.XlChartItem)ElementID)
        if (Excel.XlAxisGroup.xlPrimary == (Excel.XlAxisGroup)Arg1)
            MessageBox.Show("The primary axis of the chart was selected.");
WithEvents SelectChart As Microsoft.Office.Tools.Excel.Chart

Private Sub DisplayWhenPrimaryAxisSelected()
    Me.Range("A1", "A5").Value2 = 22
    Me.Range("B1", "B5").Value2 = 55

    SelectChart = Me.Controls.AddChart(Me.Range("D2", "H12"), _
    SelectChart.SetSourceData(Me.Range("A1", "B5"), _
    SelectChart.ChartType = Excel.XlChartType.xl3DColumn
End Sub

Sub SelectChart_SelectEvent(ByVal ElementID As Integer, _
    ByVal Arg1 As Integer, ByVal Arg2 As Integer) _
    Handles SelectChart.SelectEvent

    If Excel.XlChartItem.xlAxis = _
        CType(ElementID, Excel.XlChartItem) Then
        If Excel.XlAxisGroup.xlPrimary = _
            CType(Arg1, Excel.XlAxisGroup) Then
