Chart.BeforeDoubleClick Event

Occurs when the Chart control is double-clicked, before the default double-click action.

Namespace:  Microsoft.Office.Tools.Excel
Assembly:  Microsoft.Office.Tools.Excel (in Microsoft.Office.Tools.Excel.dll)

event ChartEvents_BeforeDoubleClickEventHandler BeforeDoubleClick

The DoubleClick method does not cause this event to occur.

The following code example creates a Chart with a handler for the BeforeDoubleClick event that displays a message box when an axis of the chart is double-clicked. The example also sets the Cancel parameter of the event handler to true so that the chart does not receive the double click action when the user double-clicks an axis.

private void DisallowDoubleClicksOnAxis()
{
    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.BeforeDoubleClick +=
        new Excel.ChartEvents_BeforeDoubleClickEventHandler(
        chart1_BeforeDoubleClick);
}

void chart1_BeforeDoubleClick(int ElementID, int Arg1, 
    int Arg2, ref bool Cancel)
{
    if (ElementID == (int)Excel.XlChartItem.xlAxis)
    {
        MessageBox.Show("Formatting this axis is not allowed.");
        Cancel = true;
    }
}
