Are there any solutions for it in version before useful EnableSelectionCaching option was added?
https://docs.telerik.com/devtools/wpf/controls/radlistbox/features/selection#disabling-caching-of-selected-items
"Disabling Caching of Selected Items
By default, when its ItemsSource is reset, RadListBox will try to restore any previously selected items through its built-in caching mechanism. As of R1 2017, RadListBox allows you to disable this functionality by setting its new EnableSelectionCaching property to False."

Hello Анатолій,
Thank you for your interest in our RadListBox control.
I am afraid I can't suggest a solution for this behavior before EnableSelectionCaching property. I would suggest you update our assemblies to their latest version. This way, you can take advantage of this property and many more features, new controls, bug fixes, etc.
