>any method can check the class of textbox is added into the gird or not?!

---

Many ways to check that :

llIsAdded = ( type("thisform.myGrid.columns(ix).myText1.name") = "C" )
* Or
llIsAdded = ( type("thisform.myGrid.columns(ix).myText1") = "O" ;
 and !isnull(thisform.myGrid.columns(ix).myText1) ;
 and lower(thisform.myGrid.columns(ix).myText1.class) = "textcl")
* Or
for each oColumn in thisform.myGrid
  llIsAdded = .f.
  for each oControl in oColumn.Controls
      if lower(oControl.class) = "textcl"
         llIsAdded = .t.
      endif
  endfor
  if !llIsAdded && Not added to this column
     messagebox("Not added to column "+str(ix,2))
  endif
endfor
*etc
