Public Methods

Method	Description
Contains ( this s, string value, System.StringComparison comparison ) : bool	An implementation of the Contains member of string that takes in a string comparison. The traditional .NET string Contains member uses StringComparison.Ordinal.
Invert ( this m, Matrix &outputMatrix ) : bool	Inverts a Matrix. The Invert functionality on the Matrix type is internal to the framework only. Since Matrix is a struct, an out parameter must be presented.
IsDarkThemeActive ( this resources ) : bool	Returns whether the dark visual theme is currently active.
IsExternalNavigation ( this uri ) : bool	Returns whether the uri is from an external source.
IsPortrait ( this orientation ) : bool	Returns whether the page orientation is in portrait.
RegisterNotification ( this element, string propertyName, PropertyChangedCallback callback ) : void	Registers a property changed callback for a given property. This allows a child to be notified of when a property declared in its parent is changed.

Method Details

Contains() public static method

An implementation of the Contains member of string that takes in a string comparison. The traditional .NET string Contains member uses StringComparison.Ordinal.

public static Contains ( this s, string value, System.StringComparison comparison ) : bool
s	this	The string.
value	string	The string value to search for.
comparison	System.StringComparison	The string comparison type.
return	bool

Invert() public static method

Inverts a Matrix. The Invert functionality on the Matrix type is internal to the framework only. Since Matrix is a struct, an out parameter must be presented.

public static Invert ( this m, Matrix &outputMatrix ) : bool
m	this	The Matrix object.
outputMatrix	Matrix	The matrix to return by an output /// parameter.
return	bool

IsDarkThemeActive() public static method

Returns whether the dark visual theme is currently active.

public static IsDarkThemeActive ( this resources ) : bool
resources	this	Resource Dictionary
return	bool

IsExternalNavigation() public static method

Returns whether the uri is from an external source.

public static IsExternalNavigation ( this uri ) : bool
uri	this	The uri
return	bool

IsPortrait() public static method

Returns whether the page orientation is in portrait.

public static IsPortrait ( this orientation ) : bool
orientation	this	Page orientation
return	bool

RegisterNotification() public static method

Registers a property changed callback for a given property.

This allows a child to be notified of when a property declared in its parent is changed.

public static RegisterNotification ( this element, string propertyName, PropertyChangedCallback callback ) : void
element	this	The element registering the notification
propertyName	string	Property name to register
callback	PropertyChangedCallback	Callback function
return	void
