I modify your sample https://forums.fivetechsupport.com/viewtopic.php?f=3&t=44500&sid=ca68d176cc14f86e1359d15301a5e80f to use with tdatabase and the possiblity to select the state but I have problem to run the cfilter
1) when I go to ResetFilter( aFilters,oDbf, nIndex ) nIndex is allways 3
2) to create a filter I select the state and create the new filter ( ru nok I put as 3)
local cState:= space(25)
If nIndex=3
Selection_State( @cstate )
cFilter:= 'STATE='+ "'"+cState+"'"
endif
see the code pls
