if you check I think you'll find you get both the cellclick and
mousedown and that's what seems to be deselecting everything
you can catch this by inserting, in the cellclick, something like
if Keyboard.AsyncControlKey or IsContextualClick then
return true
end if
and the selection will not be changed BUT the ConstructContextualMenu
will not be called either
If you could use the menuitem.popup then you could have the
contextual menu show up
You could use something like
if Keyboard.AsyncControlKey or IsContextualClick then
dim base as New MenuItem
dim m as MenuItem
m=New MenuItem
m.text="menuitem test"
base.append m
m = base.PopUp
return true
end if
Not sure how you get this effect if you have to use
ConstructContextualMenu
