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

Event BeforeDoubleClick As ChartEvents_BeforeDoubleClickEventHandler
event ChartEvents_BeforeDoubleClickEventHandler BeforeDoubleClick

The DoubleClick method does not cause this event to occur.
Examples
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.
WithEvents DoubleClickChart As Microsoft.Office.Tools.Excel.Chart
Private Sub DisallowDoubleClicksOnAxis()
Me.Range("A1", "A5").Value2 = 22
Me.Range("B1", "B5").Value2 = 55
DoubleClickChart = Me.Controls.AddChart(Me.Range("D2", "H12"), _
"DoubleClickChart")
DoubleClickChart.SetSourceData(Me.Range("A1", "B5"), _
Excel.XlRowCol.xlColumns)
DoubleClickChart.ChartType = Excel.XlChartType.xl3DColumn
End Sub
Sub DoubleClickChart_BeforeDoubleClick(ByVal ElementID As Integer, _
ByVal Arg1 As Integer, ByVal Arg2 As Integer, _
ByRef Cancel As Boolean) Handles DoubleClickChart.BeforeDoubleClick
If ElementID = Fix(Excel.XlChartItem.xlAxis) Then
MsgBox("Formatting this axis is not allowed.")
Cancel = True
End If
End Sub
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;
}
}
