Luís, I would say that Dragan pointed you into the right direction.

Assuming that your grid holds the fields of your cursor in their natural order, you must create indexes for all of the first 11 fields, regardless of their type, otherwise the code you're using will not work at all.

Hello Antonio,

Thanks for your reply.

My cursor have 21 fields (see attachment).

For i=1 To PDU_FCTEXM.Pageframe1.Udcpage3.Grid1.ColumnCount && the result of PDU_FCTEXM.Pageframe1.Udcpage3.Grid1.ColumnCount must be 21
	If Inlist(i,1,2,3,4,5,6,7,8,9,10,11)  &&choice only the column to sort asc/descending-grid can have any columnCount
		aa="PDU_FCTEXM.Pageframe1.Udcpage3.Grid1.column"+Trans(i)+".header1"
		Bindevent(&aa,"click",oHandler,"mygridinit",1)
	Endif
Endfor

I suppose the result of : For i=1 To PDU_FCTEXM.Pageframe1.Udcpage3.Grid1.ColumnCount must be equal to 21 fields
when you mencioned : "you must create indexes for all of the first 11 fields, regardless of their type, otherwise the code you're using will not work at all."
But i suppose the indexes have been create for all of the fields of my cursor.
When i click on column8, the SYS(21) return 8.

do you mean that before : set order to N in mybolistex, i must declare:
INDEX ON N TO N
set order to N in mybolistex

Sorry but i not understand, could you help me.

Best regards,
Luis
