public class PendingConnection : ContentControlConstructors
Section titled “Constructors”PendingConnection()
Section titled “PendingConnection()”public PendingConnection();Properties
Section titled “Properties”AllowOnlyConnectors
Section titled “AllowOnlyConnectors”If true will preview and connect only to Connectors, otherwise will also enable ItemContainers.
public bool AllowOnlyConnectors { get; set; }Property Value
CompletedCommand
Section titled “CompletedCommand”Gets or sets the command to invoke when the pending connection is completed. Will not be invoked if NodifyEditor.ConnectionCompletedCommand is used.

Direction
Section titled “Direction”Gets or sets the direction of this connection.
public ConnectionDirection Direction { get; set; }Property Value
Editor
Section titled “Editor”Gets the NodifyEditor that owns this PendingConnection.
protected NodifyEditor Editor { get; set; }Property Value
EnableHitTesting
Section titled “EnableHitTesting”Gets or sets whether hit testing is enabled for pending connections.
public static bool EnableHitTesting { get; set; }Property Value
EnablePreview
Section titled “EnablePreview”PendingConnection.PreviewTarget will be updated with a potential Connector’s FrameworkElement.DataContext if this is true.
public bool EnablePreview { get; set; }Property Value
EnableSnapping
Section titled “EnableSnapping”Enables snapping the PendingConnection.TargetAnchor to a possible PendingConnection.Target connector.
public bool EnableSnapping { get; set; }Property Value

public object PreviewTarget { get; set; }Property Value
Source
Section titled “Source”Gets or sets the Connector’s FrameworkElement.DataContext that started this pending connection.
public object Source { get; set; }Property Value
SourceAnchor
Section titled “SourceAnchor”Gets or sets the starting point for the connection.
public Point SourceAnchor { get; set; }Property Value
StartedCommand
Section titled “StartedCommand”Gets or sets the command to invoke when the pending connection is started. Will not be invoked if NodifyEditor.ConnectionStartedCommand is used.

StrokeThickness
Section titled “StrokeThickness”Gets or set the connection thickness.
public double StrokeThickness { get; set; }Property Value
Target
Section titled “Target”Gets or sets the Connector’s FrameworkElement.DataContext (or potentially an ItemContainer’s FrameworkElement.DataContext if PendingConnection.AllowOnlyConnectors is false) that the PendingConnection.Source can connect to. Only set when the connection is completed (see PendingConnection.CompletedCommand).
public object Target { get; set; }Property Value
TargetAnchor
Section titled “TargetAnchor”Gets or sets the end point for the connection.
public Point TargetAnchor { get; set; }Property Value
