The WPF AutoComplete control provides a common AutoComplete text box to easily select values from a predefined list and adds the common AutoComplete paradigm to text boxes. The control is loaded with features to help you customize the behavior, look, and feel in many different ways.

Multiple selection

Select multiple items from the suggestion list and display the selected items either as tokens, such as in an email address bar, or text separated by a delimiter.

Token representation

Customizable token representation in the autocomplete control allows users to remove an item with its close button.

Delimit the selected items with desired characters such as ‘$’ for dollar representation, or ‘,’ for traditional comma separation.

Delimiter support in WPF autocomplete

When a character is entered, the control searches for items related to the entered character and filters results, displaying the suggestion in the dropdown list.

Perform filtering when needed

The control starts offering matches as soon as users start typing. This feature can be changed by setting the number of characters required to start matching.


You can pick from various filtering options such as starts with, contains, and ends with. You can also choose whether to filter with or without case sensitivity.

Suggest, append, or both

The WPF autocomplete control can suggest a list of filtered items in a pop-up or append the rest of the suggested words in the input area. This can also append the matched item and display the list of filtered items suggested in a pop-up at the same time.

I am really thankful for the wonderful set of controls for WPF. I was able to deliver things on time and could focus on core business logic rather than control development.
