For a standard TextBox, the default on-screen keyboard is presented so that the first letter entered is lower-case, unless of course the user first taps the upper-case keyboard arrow. But in many cases, this is an annoying extra step for the user.
To configure the keyboard to capitalize the first letter for a
TextBox, simply set the TextBox’s
InputScope property to “PersonalFullName”. The
InputScope property controls the way in which the on-screen keyboard is displayed to the user when a particular input control is being edited.
Microsoft warns this should only be used with Silverlight for Windows Phone.
Too verbose? Setting it in XAML is cleaner.
For many text boxes that require this, a global style might be a more manageable approach.
While we’re on the subject, it’s worth checking out the other common InputScope values. For example “Text”, which enables auto-correct and text suggestion.
