I have looked your sample and compared my code.
I found the difference is I have two columns have ComboBox which is bould to thier lookup table. These two columns have thier ComboBox controls in the detail panel binding to thier lookup table as well. this is caused the slow-down. When I deleted them from the detail panel
controls( that is the detail panel have only textbox about 20), it works fast.
Could you add a ComboBox column with lookup table in your code sample to see if it slow down?
Thanks.
