    I have set a ListBox as a content for a RadDropDownButton, and I find that, after a user has selected an item from the list and clicks the button to close it, if she clicks again to re-open the list, her previous selection has been lost... I'd like to keep the same ListBox even if the user closes the button content, is there any way to achieve that?

    Hello Mrn,

    I am not sure if I understand your scenario correctly - do you display a ListBox as DropDownContent of the RadDropDownButton? If this is the case, if the ListBox.Items collection is populated in XAML then the selection should be kept even if the DropDownContent is closed and later opened.

    If the ListBox is databound to a business collection of items, then in order to keep the selection, you will need to bind the ListBoxItem IsSelected property to a property from your view models.

    I hope thins info will help you. However, if I am missing something or you need more info, please let me know.
