Set Line color in dG?

The example you mention is probably using a custom column behavior script
for accomplishing this.
Do you have copied the button in your project? The button must be linked to
your datagrid by using the following code:

set the dgProp["default column behavior"] of grp "myDatagrid" to the long
id of btn "myBtn"
