public void SetValue (System.Workflow.ComponentModel.DependencyProperty dependencyProperty, object value);

member this.SetValue : System.Workflow.ComponentModel.DependencyProperty * obj -> unit

Public Sub SetValue (dependencyProperty As DependencyProperty, value As Object)

Parameters

dependencyProperty: DependencyProperty

The DependencyProperty to be set.

value: Object

The Object to set the value to.

Examples

The following code shows how a dependency property is set within a dependency object using 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)

Remarks

SetBinding sets a binding for the dependency property.

SetValue sets a value directly to the DependencyProperty (similarly, AddHandler adds a handler directly to properties of type event).

These methods are exclusive when they are called for the same property. If SetBinding is called, then the values previously set using SetValue (AddHandler in events) are disregarded. The same is true the other way around: SetValue (AddHandler) resets the binding assigned with SetBinding.
