I have a dbgrid connected to an adodc. I can't self -errorcheck if the user is adding an incorrect value into the grid. For example I have a integer field called 'Panels' on the grid, now if the user tries to enter a non-numeric field I want to be able to pop up a msgbox saying 'error' and the put the old value back. When I tried to use the 'dbgGrid_BeforeColUpdate' I could only read the oldvalue in the cell, not the one just entered. ex if the old value was '17' and they tried to enter 'bb' I can't pass the value 'bb' into a variable, only 17. It's almost like 'bb' doesn't exist until the adodc enters it into the db. So when the adodc tries to enter the new value into the db it comes up with it's own error message, which I don't want. Please help, thanks in advance..
