Creating an Autocomplete Textbox in WPF with MVVM

Autocomplete textboxes can significantly enhance user experience by offering suggestions as users type. This guide will guide you through the process of creating an autocomplete textbox in WPF using the MVVM pattern and WPF Toolkit. We'll also cover the basics of how to create an autocomplete textbox in C WPF.

Why Use Autocomplete?

Autocomplete functionality not only helps users by providing suggestions, which can significantly speed up data entry, but it also improves overall application usability. Implementing an autocomplete textbox in a WPF application offers a modern and efficient way to handle text input and search-related functionalities.

Setting Up the Project

Before diving into the code, it's essential to set up your WPF project with the necessary libraries:

Create a New WPF Project: Open Visual Studio and create a new WPF application.

Add WPF Toolkit: To use the WPF Toolkit for autocomplete functionality, you need to add it to your project. You can do this via NuGet Package Manager by installing Extended.Wpf.Toolkit.

Implementing Autocomplete Textbox in WPF
