I use ComboBoxAdv in the Treeview control template and set AutoCompleteMode="Suggest" to filter. When there are multiple rows of data in the list, entering values in a certain row of ComboBoxAdv to filter will cause the current options of other rows of ComboBoxAdv to be cleared

Hi Wpfdev1 Kunyi,
Each combo box should have unique item sources. If you want to map to the same ItemsSource, you can create a converter that gives a new CollectionViewSource for each ItemsSource binding. Please refer to the below code snippets for your reference.
