Initializes a new instance of the AnnotationService class for use with a specified document viewing control.

Overloads

AnnotationService(FlowDocumentReader)	Initializes a new instance of the AnnotationService class for use with a specified FlowDocumentReader control.
AnnotationService(FlowDocumentScrollViewer)	Initializes a new instance of the AnnotationService class for use with a specified FlowDocumentScrollViewer control.
AnnotationService(DocumentViewerBase)	Initializes a new instance of the AnnotationService class for use with a specified DocumentViewer or FlowDocumentPageViewer control.

Examples

The following example shows use of the AnnotationService constructor.

// ------------------------ StartAnnotations --------------------------
/// <summary>
///   Enables annotations and displays all that are viewable.</summary>
private void StartAnnotations()
{
    // If there is no AnnotationService yet, create one.
    if (_annotService == null)
        // docViewer is a document viewing control named in Window1.xaml.
        _annotService = new AnnotationService(docViewer);

    // If the AnnotationService is currently enabled, disable it.
    if (_annotService.IsEnabled)
        _annotService.Disable();

    // Open a stream to the file for storing annotations.
    _annotStream = new FileStream(
        _annotStorePath, FileMode.OpenOrCreate, FileAccess.ReadWrite);

    // Create an AnnotationStore using the file stream.
    _annotStore = new XmlStreamStore(_annotStream);

    // Enable the AnnotationService using the new store.
    _annotService.Enable(_annotStore);
}// end:StartAnnotations()

' ------------------------ StartAnnotations --------------------------
''' <summary>
'''   Enables annotations and displays all that are viewable.</summary>
Private Sub StartAnnotations()
    ' If there is no AnnotationService yet, create one.
    If _annotService Is Nothing Then
        ' docViewer is a document viewing control named in Window1.xaml.
        _annotService = New AnnotationService(docViewer)
    End If

    ' If the AnnotationService is currently enabled, disable it.
    If _annotService.IsEnabled = True Then
        _annotService.Disable()
    End If

    ' Open a stream to the file for storing annotations.
    _annotStream = New FileStream(_annotStorePath, FileMode.OpenOrCreate, FileAccess.ReadWrite)

    ' Create an AnnotationStore using the file stream.
    _annotStore = New XmlStreamStore(_annotStream)

    ' Enable the AnnotationService using the new store.
    _annotService.Enable(_annotStore)
End Sub

Remarks

The AnnotationService can be used with the following document viewing controls:

FlowDocumentReader
FlowDocumentScrollViewer
DocumentViewerBase derived subclasses
- DocumentViewer
- FlowDocumentPageViewer

AnnotationService(FlowDocumentReader)

Initializes a new instance of the AnnotationService class for use with a specified FlowDocumentReader control.

public:
 AnnotationService(System::Windows::Controls::FlowDocumentReader ^ viewer);

public AnnotationService (System.Windows.Controls.FlowDocumentReader viewer);

new System.Windows.Annotations.AnnotationService : System.Windows.Controls.FlowDocumentReader -> System.Windows.Annotations.AnnotationService

Public Sub New (viewer As FlowDocumentReader)

Parameters

viewer: FlowDocumentReader

The document reading control associated with the AnnotationService.
