Emerson,

I can't really play around with the Flexgrid itself until later tonight.

You could use an off screen form (.Top = -1000, .Left = -1000) with an RTF control in it to get your line count for the data.

>This control doesn't have a property to auto adjust the height of line to accomplish the text.
>It's necessary to put the text in a RTF control and use Sendmessage to get the number of lines. By this way its possible to adjust the height of line but only works if RTF control is visible... and I want that RTF control stay invisible.
