Constructors

ReactiveObject()

Initializes a new instance of the ReactiveObject class.

public ReactiveObject()

Properties

Changed

Gets an Observable that fires after a property has changed. Note that this should not fire duplicate change notifications if a property is set to the same value multiple times.

[IgnoreDataMember]
[JsonIgnore]
[Browsable(false)]
[Display(Order = -1, AutoGenerateField = false, AutoGenerateFilter = false)]
public IObservable<IReactivePropertyChangedEventArgs<IReactiveObject>> Changed { get; }

Property Value

IObservable<IReactivePropertyChangedEventArgs<IReactiveObject>>

Changing

Gets an observable that fires before a property is about to be changed. Note that this should not fire duplicate change notifications if a property is set to the same value multiple times.

[IgnoreDataMember]
[JsonIgnore]
[Browsable(false)]
[Display(Order = -1, AutoGenerateField = false, AutoGenerateFilter = false)]
public IObservable<IReactivePropertyChangedEventArgs<IReactiveObject>> Changing { get; }

Property Value

IObservable<IReactivePropertyChangedEventArgs<IReactiveObject>>

ThrownExceptions

Gets a observable which will fire whenever an exception would normally terminate ReactiveUI internal state.

[IgnoreDataMember]
[JsonIgnore]
[Browsable(false)]
[Display(Order = -1, AutoGenerateField = false, AutoGenerateFilter = false)]
public IObservable<Exception> ThrownExceptions { get; }

Property Value

IObservable<Exception>

Methods

AreChangeNotificationsEnabled()

Determines if change notifications are enabled or not.

public bool AreChangeNotificationsEnabled()

Returns

bool

A value indicating whether change notifications are enabled.

DelayChangeNotifications()

Delays notifications until the return IDisposable is disposed.

public IDisposable DelayChangeNotifications()

Returns

IDisposable

A disposable which when disposed will send delayed notifications.

SuppressChangeNotifications()

When this method is called, an object will not fire change notifications (neither traditional nor Observable notifications) until the return value is disposed.

public IDisposable SuppressChangeNotifications()

Returns

IDisposable

An object that, when disposed, reenables change notifications.
