I don't think that an error is occuring, as a test datagrid also has  
the same behavior (does not open the next cell on tabbing).
I want with the insertion point in an open cell, with a tabKey open  
the next cell on the same line (and close the one that was open). So  
fill in a cell, hit tabKey, fill in next cell, etc.
Is it a custom property I have to set? I don't think so, as I have  
not found it.
So I tried to write a handler in the datagrid grp script (see below).

I am sure that this is easy, but after a long search and many trys, I  
just can't find the last bit.

I have the following handler, which works ok.
I only need now to get the Column name of the open cell. How will I  
do that?
  dgHilitedLines gives me the LineNr, but how to get the name of the  
Column of the open cell ?

on rawkeyDown tkey
    if tkey = 65289    then   -- tabkey
         get the dgHilitedIndexes of grp "datagrid 1"
	put it into tLineNr

--  HOW to get the Column Name of the open cell ??????

--   for now to test the rest
       put "Col 2" into tCol	
--
       set the dgHilitedLines of grp "DataGrid 1"  to tLineNr
       dispatch "EditCell" to group "DataGrid 1"  with tCol, tLineNr
-- et voila : on tabKey the next cell is opened
    end if

    pass rawkeyDown
end rawkeyDown



Many thanks & warm greetings,
