Hi Peter,
thank you for the quick replay.
I don’t need the number of items in the data source, but the number of items between min and max of the range selector as modified by the user every time the range is changed.
I have an application that needs this number of items to show what portion of the data is currently selected. In my case it will be some amount of money, calculated based on the number of items between min and max.
Of course one can loop through all the items of the data source, and check if an item is between, but it’s definitely not the smart way.
Best regards
Anton
