Hi, we found a problem after updating our project to our last available version witch is "Complimentary R1 2020 Version", we are on 2016.2.607.40, and after find a problem in radgrid and keyboard interaction we look at out download page and have the complimentary version, we try it and that problem solves, but in a recently added radfilter we discover that stop working as spectated.
We use RadFilterDropDown with radcomboboxes, which load on demand.
First, we see that load settings displays the saved info of combos in blank.
Second, we discover also that selecting a item from combo, not saving on settings and not showing on preview also
With 2016.2.607.40
With Trial version of 2023.3.1010 (we try it to see if problem solved on last version)
Attached isolated sample for reproduction
