I used two RadListBox, one is right and other left on screen.
And Explorer apply Compatibility View Settings.
So Explorer Version is IE5, but I didn't have any problems.
before upgrade telerik Version.
I used to use 2014.2.724.35 version. And now upgrade to 2016.1.225.35
And then RadListBox got a problem.
When I scrolls down and select a item. (on name)
Immediately ListBox scrolls up and uncheck that item.
If I select a item (right side name), I can check it but can't get back uncheck item...
I try to select a check item, automatically scrolls up again......
I think that is Version problem but I have to use IE5 and apply Compatibility View Settings.
How to figure out this problem...
