Mario,

You'll have to set the BackColor of the textbox/editbox control that is in the column. I believe you can do this in the When() or GotFocus().

>I’m trying to use the DynamicBackColor of a column that has the sparse properties set to .F. But when the control get the focus the backcolor is lost and it become white again.I know the problem come from the sparse because If I change the sparse to .T. everything is fine,
>But I need the sparse (the controls source is a Memo)
