Public Methods

Method	Description
CreateRegionManager ( ) : IRegionManager	Creates a new region manager.
GetObservableRegion ( DependencyObject view ) : ObservableObject	Returns an ObservableObject{T} wrapper that can hold an IRegion. Using this wrapper you can detect when an IRegion has been created by the RegionAdapterBase{T}. If the ObservableObject{T} wrapper does not yet exist, a new wrapper will be created. When the region gets created and assigned to the wrapper, you can use the ObservableObject{T}.PropertyChanged event to get notified of that change.
GetRegionContext ( DependencyObject target ) : object	Gets the value of the RegionContextProperty attached property.
GetRegionManager ( DependencyObject target ) : IRegionManager	Gets the value of the RegionNameProperty attached property.
GetRegionName ( DependencyObject regionTarget ) : string	Gets the value for the RegionNameProperty attached property.
RegionManager ( ) : System	Initializes a new instance of RegionManager.
SetRegionContext ( DependencyObject target, object value ) : void	Sets the RegionContextProperty attached property.
SetRegionManager ( DependencyObject target, IRegionManager value ) : void	Sets the RegionManagerProperty attached property.
SetRegionName ( DependencyObject regionTarget, string regionName ) : void	Sets the RegionNameProperty attached property.
UpdateRegions ( ) : void	Notifies attached behaviors to update the region managers appropriatelly if needed to. This method is normally called internally, and there is usually no need to call this from user code.

Method Details

CreateRegionManager() public method

Creates a new region manager.

public CreateRegionManager ( ) : IRegionManager
return	IRegionManager

GetObservableRegion() public static method

Returns an ObservableObject{T} wrapper that can hold an IRegion. Using this wrapper you can detect when an IRegion has been created by the RegionAdapterBase{T}. If the ObservableObject{T} wrapper does not yet exist, a new wrapper will be created. When the region gets created and assigned to the wrapper, you can use the ObservableObject{T}.PropertyChanged event to get notified of that change.

public static GetObservableRegion ( DependencyObject view ) : ObservableObject
view	DependencyObject	The view that will host the region.
return	ObservableObject

GetRegionContext() public static method

Gets the value of the RegionContextProperty attached property.

public static GetRegionContext ( DependencyObject target ) : object
target	DependencyObject	The target element.
return	object

GetRegionManager() public static method

Gets the value of the RegionNameProperty attached property.

public static GetRegionManager ( DependencyObject target ) : IRegionManager
target	DependencyObject	The target element.
return	IRegionManager

GetRegionName() public static method

Gets the value for the RegionNameProperty attached property.

public static GetRegionName ( DependencyObject regionTarget ) : string
regionTarget	DependencyObject	The object to adapt. This is typically a container (i.e a control).
return	string

RegionManager() public method

Initializes a new instance of RegionManager.

public RegionManager ( ) : System
return	System

SetRegionContext() public static method

Sets the RegionContextProperty attached property.

public static SetRegionContext ( DependencyObject target, object value ) : void
target	DependencyObject	The target element.
value	object	The value.
return	void

SetRegionManager() public static method

Sets the RegionManagerProperty attached property.

public static SetRegionManager ( DependencyObject target, IRegionManager value ) : void
target	DependencyObject	The target element.
value	IRegionManager	The value.
return	void

SetRegionName() public static method

Sets the RegionNameProperty attached property.

public static SetRegionName ( DependencyObject regionTarget, string regionName ) : void
regionTarget	DependencyObject	The object to adapt. This is typically a container (i.e a control).
regionName	string	The name of the region to register.
return	void

UpdateRegions() public static method

Notifies attached behaviors to update the region managers appropriatelly if needed to.

This method is normally called internally, and there is usually no need to call this from user code.

public static UpdateRegions ( ) : void
return	void

Property Details

RegionContextProperty public_oe static_oe property

Identifies the RegionContext attached property.

public static DependencyProperty RegionContextProperty
return	DependencyProperty

RegionManagerProperty public_oe static_oe property

Identifies the RegionManager attached property.

When a control has both the RegionNameProperty and RegionManagerProperty attached properties set to a value different than and there is a IRegionAdapter mapping registered for the control, it will create and adapt a new region for that control, and register it in the IRegionManager with the specified region name.

public static DependencyProperty RegionManagerProperty
return	DependencyProperty

RegionNameProperty public_oe static_oe property

Identifies the RegionName attached property.

public static DependencyProperty RegionNameProperty
return	DependencyProperty
