Input Extensions

Provides various attached properties for input controls, such as TextBox and PasswordBox.

Attached Properties

Property	Type	Description
AutoDismiss	bool	Whether the soft-keyboard will be dismissed when the enter key is pressed.
AutoFocusNext	bool	Whether the focus will move to the next focusable element when the enter key is pressed.*
AutoFocusNextElement	Control	Sets the next control to focus when the enter key is pressed.*

AutoFocusNext and AutoFocusNextElement*: Having either or both of the two properties set will enable the focus next behavior. AutoFocusNextElement will take precedences over AutoFocusNext when both are set.

Remarks

• AutoFocusNext and AutoFocusNextElement have different focus target:
  • AutoFocusNext is determined by FocusManager.FindNextFocusableElement
  • AutoFocusNextElement is provided by the value.
