>I have a grid with a command button in one of the columns. The command button activates an editing window for editing a memo field. I want to signify to the user which records have memo info and which don't. I used the following code:
>
>THIS.FontBold=IIF(MEMLINES(Comments)>0,.T.,.F.)
>THIS.Refresh
>
>This makes the caption in the command button for all records bold. How do I apply the above code for each individual record in the grid?

You should use Column.DynamicFontBold property.
