I can not down load that PDF.. Every step I take its trying to get me to install software I don't want and sign up for services that will cost me in the end..
A simple PNG image which is small attached here would of been just fine..
I just down loaded a 10-10EZ health benefit form.
In any case If you are looking to use scattered layout then I guess a Tgrid is out of the question I would think
But if they are in a formatted arrangement then you can use the TStringGrid and select an editor for the cell..
The grid lines can be set for thick lines, color etc.
If you don't like that idea, then a bunch of panels with anchors to each other with the edit controls inside..
how many boxes are going to be alive here ?
EDIT:
have you considered using a Spread sheet component ?
That will allow you to have enter fields, adjust your lines etc.
