Hi I use an CExtGridCellComboBox in a CExtGridWnd. In the method OnGridCellInputComplete I get the item data of the _cell parameter (which is a pointer in my case) and work with the referenced object. Now during this processing, an error can occur. This error I show within a message box. The problem is: when the message box appears, the drop down list of the comboBox grid cell is still visible. It disappears when I click somewhere else on the screen. This is very annoying for I need two clicks to confirm the message box: The first lets disappear the drop down list and second will be accepted by the message box. We use v2.70 Thanks Christian Herger

The popup list box is a popup menu with a list box common control inside. The CExtPopupMenuWnd::CancelMenuTracking() static method closes any currently opened popup menus. You should invoke it before displaying a message box.
