DataBound ComboBox bound to DataTable of 2 columns with 1000 items (ZIP codes) is too slow when current selection is changed via
SelectedValue. It tooks even 300ms on my i3 4GB W7 64bit.
In case of form with 10 combos on detail UI becames unusable in master/detail scenario.
If I implemented some FindRow method and current item is selected via SelectedIndex it works fine
(at least it tooks 10-times less time).
Every possible change events are blocked during call of SelectedValues.
Any ideas how to correct this issue?
Thanks in advance.
