Call cellvalidating event
If the value is not the one you want, call the code you have up there.
New Values("Column_Name_In_Your_Database_Table_For_Column B_In_Your_Grid") = Convert. Cancel = True End Sub Hi mezzanie, If i am not mistaken, Row Updating is fired when we press on Update button, isn't it? Text Changed event with Auto Post Back=true surely will can do all what i want.
