    I was working on implementing a combobox and autocomplete feature in my test application, as seen in the attached files. The features work well, but when I update the C1.WPF.Input to version 6.0, I encounter issues. I am unable to delete the selected item(it selects first item), and I cannot select the correct item. the event of ValidateInput works weired.

    Is there a way to ensure compatibility with version 6.0 of the C1 component? I have a license for the 2021 C1 component, and I’d like to make it work correctly with this version.
