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.*
ReturnType	InputReturnType	The type of return button on a soft keyboard for Android/iOS. It can be one of the following options: Default, Done, Go, Next, Search, Send.

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

Remarks

  • AutoFocusNext is determined by FocusManager.FindNextFocusableElement
  • AutoFocusNextElement is provided by the value.
