During a form design I used dbgrid and associated it to a table.
One column of the grid i replaced with a class combo box for which data will be fetched from another table ie. row source is another table. During execution in that column after reacing the last record of the combo if a down arrow is pressed it gives a Fatal Exception error and terminates the program. But this works fine without a Grid.
Please if there is a solution then reply to nithikumar@eth.net
