By Default WPF pre-install text box control does not come with an auto complete/suggestion feature. There are many 3rd party libraries out there which provide auto complete/suggestion text box control as a replacement to default WPF text box control. Most of these libraries are available in paid version and those which are available for free, are difficult to get integrated with your existing code. So, I have created a very simple Auto Complete/Suggestion control for WPF platform without using any external library. You can easily integrate my control in your project.
