Mark,

What is the RecordSource of the grid? If it's a cursor and you are reissuing the SELECT to generate it then you are causing the grid to self destruct and rebuild itself, when it rebuilds it uses baseclass controls and default settings for everything.

The best way around this is to use a View. You can also temporarily empty the RecordSource, do the SELECT and then reset the RecordSource
