Příklady

Následující kód ukazuje, jak je vlastnost závislosti nastavena v rámci objektu závislosti pomocí SetValue.

System.Workflow.ComponentModel.ActivityBind activityBind1 = new System.Workflow.ComponentModel.ActivityBind();
this.SampleReplicatorChildActivity1 = new SampleReplicatorChildActivity();
this.ReplicatorWork = new System.Workflow.Activities.ReplicatorActivity();
//
// SampleReplicatorChildActivity1
//
this.SampleReplicatorChildActivity1.InstanceData = null;
this.SampleReplicatorChildActivity1.Name = "SampleReplicatorChildActivity1";
activityBind1.Name = "SimpleReplicatorWorkflow";
activityBind1.Path = "ChildData";
//
// ReplicatorWork
//
this.ReplicatorWork.Activities.Add(this.SampleReplicatorChildActivity1);
this.ReplicatorWork.ExecutionType = System.Workflow.Activities.ExecutionType.Sequence;
this.ReplicatorWork.Name = "ReplicatorWork";
this.ReplicatorWork.ChildInitialized += new System.EventHandler<System.Workflow.Activities.ReplicatorChildEventArgs>(this.ChildInitializer);
this.ReplicatorWork.SetBinding(System.Workflow.Activities.ReplicatorActivity.InitialChildDataProperty, ((System.Workflow.ComponentModel.ActivityBind)(activityBind1)));

Dim activityBind1 As New System.Workflow.ComponentModel.ActivityBind()
Me.SampleReplicatorChildActivity1 = New SampleReplicatorChildActivity()
Me.ReplicatorWork = New System.Workflow.Activities.ReplicatorActivity()
' 
' SampleReplicatorChildActivity1
' 
Me.SampleReplicatorChildActivity1.InstanceData = Nothing
Me.SampleReplicatorChildActivity1.Name = "SampleReplicatorChildActivity1"
activityBind1.Name = "SimpleReplicatorWorkflow"
activityBind1.Path = "ChildData"
' 
' ReplicatorWork
' 
Me.ReplicatorWork.Activities.Add(Me.SampleReplicatorChildActivity1)
Me.ReplicatorWork.ExecutionType = System.Workflow.Activities.ExecutionType.Sequence
Me.ReplicatorWork.Name = "ReplicatorWork"
AddHandler Me.ReplicatorWork.ChildInitialized, AddressOf Me.ChildInitializer
Me.ReplicatorWork.SetBinding(System.Workflow.Activities.ReplicatorActivity.InitialChildDataProperty, activityBind1)

Poznámky

SetBinding nastaví vazbu pro vlastnost závislosti.

SetValue nastaví hodnotu přímo na DependencyProperty hodnotu (podobně AddHandler přidá obslužnou rutinu přímo do vlastností události typu).

Tyto metody jsou výhradní, pokud jsou volána pro stejnou vlastnost. Pokud SetBinding je volána, hodnoty dříve nastavené pomocí SetValue (AddHandler v událostech) jsou ignorovány. Totéž platí i jinak: SetValue (AddHandler) resetuje vazbu přiřazenou SetBinding.
