Type Parameters
- TSource
The type of source.
- TWindowOpening
The type of window opening.
- TWindowClosing
The type of window closing.
Parameters
- source
Type: System.IObservable<TSource>
The source sequence to produce windows over.
- windowOpenings
Type: System.IObservable<TWindowOpening>
The observable sequence whose elements denote the creation of new windows.
- windowClosingSelector
Type: System.Func<TWindowOpening, IObservable<TWindowClosing>>
A function invoked to define the closing of each produced window.
Return Value
Type: System.IObservable<IObservable<TSource>>
An observable sequence of windows.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type IObservable<TSource>. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
