Parameters

Examples

The following code example uses the GetChartElement method to display the chart element when a user clicks the chart.

private void DisplayChartElement()
{
    Globals.Sheet1.Range["A1", "A5"].Value2 = 22;
    Globals.Sheet1.Range["B1", "B5"].Value2 = 55;

    this.SetSourceData(Globals.Sheet1.Range["A1", "B5"],
        Excel.XlRowCol.xlColumns);
    this.ChartType = Excel.XlChartType.xlColumnClustered;

    this.MouseDown +=
        new Excel.ChartEvents_MouseDownEventHandler(ChartSheet_MouseDown);
}

void ChartSheet_MouseDown(int Button, int Shift, int x, int y)
{
    Int32 elementID = 0;
    Int32 arg1 = 0;
    Int32 arg2 = 0;

    this.GetChartElement(x, y, ref elementID, ref arg1, ref arg2);

    MessageBox.Show("Chart element is: " + ((Excel.XlChartItem)elementID).ToString()
        + "\n arg1 is: " + arg1.ToString() + "\n arg2 is: " + arg2.ToString());
}

Private Sub DisplayChartElement()
    Globals.Sheet1.Range("A1", "A5").Value2 = 22
    Globals.Sheet1.Range("B1", "B5").Value2 = 55

    Me.SetSourceData(Globals.Sheet1.Range("A1", "B5"), _
        Excel.XlRowCol.xlColumns)
    Me.ChartType = Excel.XlChartType.xlColumnClustered
End Sub

Sub ChartSheet_MouseDown(ByVal Button As Integer, ByVal Shift As Integer, _
    ByVal x As Integer, ByVal y As Integer) Handles Me.MouseDown

    Dim elementID As Integer = 0
    Dim arg1 As Integer = 0
    Dim arg2 As Integer = 0

    Me.GetChartElement(x, y, elementID, arg1, arg2)

    MsgBox("Chart element is: " & CType(elementID, Excel.XlChartItem).ToString() _
            & Constants.vbNewLine & "arg1 is: " & arg1.ToString() _
            & Constants.vbNewLine & "arg2 is: " & arg2.ToString())
End Sub

Remarks

This method is unusual in that you specify values for only the first two arguments. Microsoft Office Excel fills in the other arguments, and your code should examine those values when the method returns.

The value of ElementID after the method returns determines whether Arg1 and Arg2 contain any information, as shown in the following table.

The following table describes the meaning of Arg1 and Arg2 after the method returns.
