>>I have a grid in a form to add records in a table. When the user begins adding records the performance is very good; but each time adds new record the execution of the form is slower. When he has append several records, is necesary to close form and reenter in order to have a good performance. ¿Any help on this?

Cetin,
I have no methods tha operates on whole table, except a sum command that use first a seek one and then sum rest... while. But i think this cannot be the problem cause if you close form and execute it again the performance returns good.

About 'activerow' propertie, i'm using it only in order to save which record we are editing:

m.fila = grid.activerow
activatecell(grid.activatecell(m.fila, 1)

Maybe this is the problem ??? If yes, How can i write a method that work only when the user moves into another row to ask him to save changes or not ???. I have the cursor with the buffermodeoverride propertie set to 4.
