John,
Below sample is a grid that's just dropped from control toolbar (default grid - columncount -1).

* Init
with this
select .f. as lSelected,* ;
	from home()+"samples\data\customer" ;
	into cursor myCursor 
local lcAliasName
lcAliasName = "tcSelector"+padl(select(0),3,"0")
use (dbf("myCursor")) in 0 again alias (lcAliasName)
select (lcAliasName)
    .recordsource = lcAliasName
    .columns(1).addobject("Check1","Checkbox")
    .columns(1).currentcontrol = "Check1"
    .columns(1).Check1.caption = ""
    .columns(1).Check1.visible = .t.
    .columns(1).sparse = .f.
endwith
