e.g. : Row where BLOBfield is empty : background color row = white
ROw where BLOBfield is not empty : background color row = light grey
Can anyone give me a hint ?

Create a VIEW on which you will base the listview:
CREATE VIEW MyView (MyCol1, MyCol2, BackgroundColor) AS +
SELECT MyCol1, MyCol2, (IFNULL(MyBlobCol, 'WHITE', 'SILVER'))
FROM MyTable
Then, link the listview to this view (not the original table) and in the Row
Background Color Field dropdown select the column BackgroundColor.
By coincidence, I was working on just such a listview scheme (I also change the
font color to indicate another dimension of the data) when I read your message.
