In our application we use CExtGridCellComboBox inside CExtGridWnd.

We need to add more than 10000 items in the CExtGridCellComboBox

It’s very slow to open the list inside the CExtGridCellComboBox.

The slowness comes from the function CExtpopupmeuwnd::trackpopupmenu

We have the same problem in your sample profuis_control

How to resolve this problem ?


best regards
