A Delegate type used to add an event handler for the BeforeDoubleClick event. The BeforeDoubleClick event occurs when an embedded chart is double-clicked, before the default double-click action.

Namespace: Microsoft.Office.Interop.Excel
Assembly: Microsoft.Office.Interop.Excel (in microsoft.office.interop.excel.dll)

Usage

Sub Sub1(ElementID As Integer, _
    Arg1 As Integer, _
    Arg2 As Integer, _
    Cancel As Boolean)
End Sub
Dim chartEvents_BeforeDoubleClickEventHandler1 As New ChartEvents_BeforeDoubleClickEventHandler(AddressOf Sub1)

Syntax

Public Delegate Sub ChartEvents_BeforeDoubleClickEventHandler( _
    <InAttribute()> ByVal ElementID As Integer, _
    <InAttribute()> ByVal Arg1 As Integer, _
    <InAttribute()> ByVal Arg2 As Integer, _
    <InAttribute(), OutAttribute()> ByRef Cancel As Boolean _
)

public delegate void ChartEvents_BeforeDoubleClickEventHandler(
    [In] int ElementID, 
    [In] int Arg1, 
    [In] int Arg2, 
    [In, Out] ref bool Cancel
);

public delegate Void ChartEvents_BeforeDoubleClickEventHandler(
    Int32 ElementID, 
    Int32 Arg1, 
    Int32 Arg2, 
    &Boolean Cancel
);

public delegate void ChartEvents_BeforeDoubleClickEventHandler(
    /*in*/int ElementID, 
    /*in*/int Arg1, 
    /*in*/int Arg2, 
    /*in*/boolean Cancel
);

In JScript, you can use the delegates in the .NET Framework, but you cannot define your own.

Parameters

• ElementID
  Required. The double-clicked object.

• Arg1
  Depends on ElementID.

• Arg2
  Depends on ElementID.

• Cancel
  Optional. False when the event occurs. If the event procedure sets this argument to True, the default double-click action isn't performed when the procedure is finished.
