Hi Cetin
the dynamicbackcolor and all dynamic...properties are applyed to grid.colum object
also there is not dynamicGrilinecolor property.

gridlinecolor is a specific grid property (not a column property).
then cannot use the dynamic methods
can apply one color at once on any grid with (gridlines=1,2,3)

for ex:

with  thisform.grid1
.gridlinecolor= getcolor()
endwith

even using the "dynamicfontbold" as "fake method" cannot make grid lines colored as wanting.
i tried this method but the colors are rendered screen by screen (instead line by line for ex.) and the vertical scrollbar is blocked (grid.scrollbars=2) ! only the mousewheel works !
can you solve this problem ?
