I originally started looking for how to make a TextBox have autocomplete capability. Strangely all the articles said that it couldn’t be done. The last thing you want is for your applications to make your users struggle entering information when every other application gives them a quicker entry method. So what is the solution?
The TextBox tag has an InputScope property which if you set it to Text it builds a dictionary list as the user types. For the other InputScope types it mainly changes the keyboard defaults.
In all this one small change can have a large impact on the usability of your app.
