XAML Values

cursorName
The name of one of the predefined mouse pointer static properties in the Cursors class, or the literal string Default. See Remarks.

Name	Description
Default	An element expresses no mouse pointer preference. If the element's parent specifies a mouse pointer, that mouse pointer is displayed.
Arrow	An arrow mouse pointer. This is typically the default mouse pointer. The Arrow mouse pointer
Hand	A hand mouse pointer. This shape typically indicates that the mouse pointer is over a link. The Hand mouse pointer
Wait	A wait (or hourglass) mouse pointer. This mouse pointer typically indicates that the runtime is busy performing an operation. The Wait mouse pointer
IBeam	An I-beam mouse pointer. This mouse pointer typically indicates that text can be manipulated or selected. The I-beam mouse pointer
Stylus	A stylus mouse pointer. This mouse pointer typically indicates that pen input is being captured. The Stylus mouse pointer
Eraser	An eraser mouse pointer. This mouse pointer typically indicates that previous pen input is being deliberately erased. The Eraser mouse pointer
None	No mouse pointer is used. No mouse pointer

The Cursor type exposes the following members.

Methods

	Name	Description
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns the string representation of the Cursor. (Overrides Object.ToString().)

Remarks

The Cursors class defines a set of default mouse pointers as static properties. The Cursor class keeps a static value internally. That static value is set either by the system or by specifically setting properties that take a Cursor in XAML or code.

In Silverlight 1.0 or the JavaScript API for Silverlight, the Cursors values are an enumeration (and are actually named MouseCursor). In Silverlight 5 or the managed API, the Cursors values are static property values. In WPF, the cursor/mouse pointer image choice is extensible under full trust. Extensibility for cursors is not enabled in Silverlight 5; you must use the images that correspond to the static property values.

There is no Cursors.Default static property value. Instead, the default cursor is represented in code by setting a Cursor property value to nulla null reference (Nothing in Visual Basic). A value of "Default" is permissible as a XAML attribute usage for this case, mainly to support previous version compatibility. "Default" and "None" are not equivalent.
