Hi Nick,

It seems to be hard to implement it via the winform context menu.
I think we would better do it by change the default cell contextmenu, i.e.
the menu which will be shown when we right click on the sheet.
Here goes the code snippet.

<Code snippet
public ContextMenu m_RMBContextMenu = null;
Excel.Application exApp=null;
Microsoft.Office.Core.CommandBarButton cbb=null;
Microsoft.Office.Core.CommandBar t=null;

public void NewWorkbook(Excel.Workbook Wb)
{
System.Diagnostics.Debug.WriteLine("NewWorkbook");
exApp = Wb.Application;
object type = 1;
object oMissing = System.Reflection.Missing.Value;
//find the cell menu and then disable all and then add the ones we want
int cnt =
(int)exApp.CommandBars.GetType().InvokeMember("Cou nt",System.Reflection.Bind
ingFlags.GetProperty,null,exApp.CommandBars,new object[]{});
for( int i =1 ;i<=cnt;i++)
{
t =
(Microsoft.Office.Core.CommandBar)exApp.GetType(). InvokeMember("CommandBars"
,System.Reflection.BindingFlags.GetProperty,null,e xApp,new object[]{i});
if (t.Name == "Cell")
{
t.Reset();
for(int j =1;j<=t.Controls.Count;j++)
t.Controls[j].Visible = false;
cbb =
(Microsoft.Office.Core.CommandBarButton)t.Controls .Add(type,oMissing,oMissin
g,oMissing,oMissing);
break;
}
}
cbb.Caption = "Hello";
cbb.Click+=new
Microsoft.Office.Core._CommandBarButtonEvents_Clic kEventHandler(cbb_Click);
}

private void cbb_Click(Microsoft.Office.Core.CommandBarButton Ctrl, ref
bool CancelDefault)
{
Console.WriteLine("cbb_Click");
}

public void WorkbookBeforeClose(Excel.Workbook Wb, ref bool Cancel)
{
t.Reset(); //reset the menu
System.Diagnostics.Debug.WriteLine("WorkbookBefore Close");
}
<Code snippet
