Dear all,

In my design, a grid host a table which show the range of a control field:

Column1 Column2 Column3
control field Range from Range to
---------------------------------------------
A 10000 19999
B 20000 39999
C 40000 89999

I edit the grid by a commandbutton EditItem which set theGrid.readonly to .f.

How can I do that when I lost focus from colum2 or column3, It compare the value of the cell with the record before and after, say if the column2 of control field is <20000, a prompt warns me to check the entry.

Wit regards,

Ransome
