Public propertyNameGets or sets the name of the Activity that the ActivityBind points to.
Public propertyPathGets or sets the path for a member of the target activity. The value can use dotted notation to indicate a path to a nested value. For example, a path of "A.B.C" indicates that the ActivityBind is to a field or property named 'C', which is a member of the field or property 'B', which in turn is a field or property 'A', which is a member of the target activity.
Public propertyUserDataGets an IDictionary of user data relating to this instance.

NoteNote

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

ActivityBind allows data to flow from one activity to another activity within a workflow. ActivityBind is a declarative way of doing what otherwise must be accomplished using code, and therefore is a key element of most workflows that are written entirely in XAML markup.

ActivityBind represents a bind expression that has an Activity member as a target. The target activity member can be a property, an event, or a field. An Activity property or method can use ActivityBind to bind to another Activity member.

For example, if activity1 has property1 set to some value and if activity2 has its property1 set to ActivityBind with Name="activity1" and Path="property1", at run time the activity2.property1 gets its value from activity1.property1.
