When i scroll with mouse roll opened dblookupcombobox, dataset is scrolled.
When i scroll with mouse roll closed dblookupcombobox, dataset is not scrolled, stands in the same position.
Can I fix it somehow?
It's not a bug, but a feature.
When you scroll the information with mouse wheel on a closed dblookupcombobox, the new information is selected one-by-one and dataset position is changed accordingly.
When you scroll the information with mouse wheel on an opened dblookupcombobox, no new information is selected until you left-click on it because you are only checking the possibilities, so dataset position is not changed until you left-click with mouse on the correct information you want to select.
