Suggest and Append function in wpf

You're right, ComboBox in WPF doesn't support that, because team didn't want it to. You can read more about ComboBox in WPF here: http://www.c-sharpcorner.com/UploadFile/mahesh/wpf-combobox/

Now the thing is that WPF does support editing the template of the controls. This way, you will be able to edit the template of the ComboBox and support additional features yourself! Right click the ComboBox control, select Edit Template.

Visual Studio would generate the XAML content, which you can use to add the functionality. AutoComplete is very much simple, you can read this article of mine to learn more: http://www.c-sharpcorner.com/UploadFile/201fc1/autocomplete-textbox-in-wpf-using-only-net-and-wpf-librari/
