here is a coding from Taiwan HP, someone claim that this code has an idea to do incremental search of combox in grid!
But I need to debug a lot as his coding is not mature enough...
Would it work or find any bugs, pls help!

---

Pre Setting:

cobGrd.controlsource = Orditems.item
cobGrd.Rowsource = item
cobGrd.RowsourceType = 2 && alias and suppose item.item is 1st field

Proc.:

* cobGrd.Interactivechange()
select (This.RowSource)
xpos = this.selstart
SearchField = this.RowSource + Right(This.controlsource, LEN(This.Controlsource) - Rat(".", This.controlsource)+1)
*messagebox("&SearchField VALUE IS:"+CHR(13)+EVAL("&SearchField") + " : " + this.text, 64, "msg") && Debuging message
SearchValue = EVAL("&SearchField")
if alltrim(This.text) <> alltrim(SearchValue)
locate for SearchField = Substr(This.text, 1, xpos)
if .not.eof()
this.displayvalue = EVAL("&SearchField")
endif
endif
endif
This.selstart = xpos

---

* cobGrd.Valid()
This.value = this.displayValue
Replace (this.controlsource) with this.value

---

Since this CobGrd is not mature enough, I need help and consider is it
possible to do search in grid!

Anyway, it is for interest only, I have drop the idea on using Combox in grid for many data!
