The ExecuteContextMenu event notifies your application that the user selects a custom context menu item. Use the ContextMenuItems property to add custom items to the control's context menu. Use the AllowContextMenu property  to allow the control's context menu. The ExecuteContextMenu event is not fired if the user selects one of the default entries in the control's context menu such us: Undo, Copy, and so on.

The following VB sample adds some custom entries to the control's context menu, and prints the selected item, when the user selects it from the control's context menu:  

Private Sub Form_Load()
    With Expression1
        .AllowContextMenu = True
        .ContextMenuItems = vbCr & "Item 1" & vbCr & vbCr & "Item 2" & vbCr & "Item 3"
    End With
End Sub

Private Sub Expression1_ExecuteContextMenu(ByVal Item As String, ByVal Position As Long)
    Debug.Print "The user selects the '" & Item & "' item. The item's position is " & Position & "."
End Sub

The following C++ sample adds some custom entries to the control's context menu, and prints the selected item, when the user selects it from the control's context menu: 

m_edit.SetAllowContextMenu( TRUE );
CString strCustom( "\r" );
strCustom += "Item 1";
strCustom += "\r\r";
strCustom += "Item 2";
strCustom += "\r";
strCustom += "Item 3";
m_edit.SetContextMenuItems( strCustom );

void OnExecuteContextMenuExpression1(LPCTSTR Item, long Position) 
{
	OutputDebugString( Item );
}

The following VB.NET sample adds some custom entries to the control's context menu, and prints the selected item, when the user selects it from the control's context menu: 

With AxExpression1
    .AllowContextMenu = True
    .ContextMenuItems = vbCr & "Item 1" & vbCr & vbCr & "Item 2" & vbCr & "Item 3"
End With

Private Sub AxExpression1_ExecuteContextMenu(ByVal sender As Object, ByVal e As AxEXPRESSIONLib._IExpressionEvents_ExecuteContextMenuEvent) Handles AxExpression1.ExecuteContextMenu
    Debug.WriteLine(e.item)
End Sub

The following C# sample adds some custom entries to the control's context menu, and prints the selected item, when the user selects it from the control's context menu: 

axExpression1.AllowContextMenu = true;
axExpression1.ContextMenuItems = "\rItem1\r\rItem2\rItem3";

private void axExpression1_ExecuteContextMenu(object sender, AxEXPRESSIONLib._IExpressionEvents_ExecuteContextMenuEvent e)
{
	System.Diagnostics.Debug.WriteLine(e.item);
}

The following VFP sample adds some custom entries to the control's context menu, and prints the selected item, when the user selects it from the control's context menu:

with thisform.Expression1
	.AllowContextMenu = .t.
	.ContextMenuItems = chr(13) + "Item 1" + chr(13) + chr(13) + "Item 2" + chr(13) + "Item 3"
