Auto Complete Support in WPF ComboBox

You can able to find the expected item from the dropdown of the ComboBoxAdv and it can be enabled by using the AutoCompleteMode property. It can be used for both single and multiple selections on editable mode.

ComboBoxAdv comboBox = new ComboBoxAdv();       
combobox.AutoCompleteMode = AutoCompleModes.Suggest;
