I had this problem in VFP6 and still in VFP8.
One of the suggestions was to put the code in the Column's Valid()
instead of the Textbox's Valid(). In VFP8, there's no Valid or
InteractiveChange event for columns.

i put a dtpicker to column in a grid, i set sparce property to .f.  in a
column, i link to datetime field, however when give click a dtpicker, in run
time, this are visible i doit a date change, but if i move to another column
this dtpicker are invisible or vanish... thanks....

The following code will enable me to have alternate rows in a gird
appear as different colours;
     cexpr = "IIF(MOD(RECNO('customer'),2) = 0, RGB(255,0,0), ;
        RGB(0,255,0))"

I have a combo box A in my grid.  Combo box A has a rowsource type of
a sql with the rowsource being a select statement into a cursor for
that combo box:
SELECT cName,ID FROM CredCard WHERE lActive Order By 1 INTO CURSOR

VFP6   W98SE
The Valid event in my 3-column grid won't execute. I placed the code
in
 ..myGrid.Column2.Text1.Valid()

I am creating a cursor and entering data in by using a grid on  form.  If I
INDEX on a key then the records disappears from the grid. However they stay
in the cursor.
Please help!!!
