Flowchart Class

Definition

Represents the models workflows using the familiar flowchart paradigm.

public ref class Flowchart sealed : System::Activities::NativeActivity
[System.Windows.Markup.ContentProperty("Nodes")]
public sealed class Flowchart : System.Activities.NativeActivity
[<System.Windows.Markup.ContentProperty("Nodes")>]
type Flowchart = class
    inherit NativeActivity
Public NotInheritable Class Flowchart
Inherits NativeActivity
Inheritance
Attributes

Examples

The following code sample demonstrates creating a Flowchart activity. This example is from the Fault Handling in a Flowchart Activity Using TryCatch sample.

Flowchart flowChart = new Flowchart
{
    DisplayName = "Promotional Discount Calculation",
    Variables = {discount, promo, numberOfKids},
    StartNode = promoCodeSwitch,
    Nodes =
    {
        promoCodeSwitch,
        singleStep,
        mnkStep,
        mwkStep,
        discountDefault,
        flowDecision,
        discountApplied,
        discountNotApplied
    }
};

Remarks

The Flowchart activity allows free-form creation of a workflow using nodes and links.

Constructors

Flowchart()

Creates a new instance of the Flowchart class.

Properties

CacheId

Gets the identifier of the cache that is unique within the scope of the workflow definition.

(Inherited from Activity)
CanInduceIdle

Gets or sets a value that indicates whether the activity can cause the workflow to become idle.

(Inherited from NativeActivity)
Constraints

Gets a collection of Constraint activities that can be configured to provide validation for the Activity.

(Inherited from Activity)
DisplayName

Gets or sets an optional friendly name that is used for debugging, validation, exception handling, and tracking.

(Inherited from Activity)
Id

Gets an identifier that is unique in the scope of the workflow definition.

(Inherited from Activity)
Implementation

The execution logic of the activity.

(Inherited from NativeActivity)
ImplementationVersion

Gets or sets the implementation version of the activity.

(Inherited from NativeActivity)
Nodes

Gets or sets the collection of FlowNode objects contained by the flowchart.

StartNode

Gets or sets the FlowNode to be executed when the flowchart starts.

ValidateUnconnectedNodes

Gets or sets a value that indicates whether unconnected nodes are validated.

Variables

Gets or sets the collection of Variable objects associated with the Flowchart, which are available to share state across the child activities contained within the Flowchart.

Methods

Abort(NativeActivityAbortContext)

When implemented in a derived class, takes actions in response to the activity being aborted.

(Inherited from NativeActivity)
CacheMetadata(ActivityMetadata)

Not implemented. Use the CacheMetadata(NativeActivityMetadata) method instead.

(Inherited from NativeActivity)
CacheMetadata(NativeActivityMetadata)

Creates and validates a description of the activity's arguments, variables, child activities, and activity delegates.

(Inherited from NativeActivity)
Cancel(NativeActivityContext)

When implemented in a derived class, runs logic to cause graceful early completion of the activity.

(Inherited from NativeActivity)
Equals(Object)

Determines whether the specified object is equal to the current object.

(Inherited from Object)
Execute(NativeActivityContext)

When implemented in a derived class, runs the activity's execution logic.

(Inherited from NativeActivity)
GetHashCode()

Serves as the default hash function.

(Inherited from Object)
GetType()

Gets the Type of the current instance.

(Inherited from Object)
MemberwiseClone()

Creates a shallow copy of the current Object.

(Inherited from Object)
OnCreateDynamicUpdateMap(NativeActivityUpdateMapMetadata, Activity)

Raises an event when creating a map for the dynamic update.

(Inherited from NativeActivity)
OnCreateDynamicUpdateMap(UpdateMapMetadata, Activity)

Raises an event when creating a map for the dynamic update.

(Inherited from NativeActivity)
ShouldSerializeDisplayName()

Indicates whether the DisplayName property should be serialized.

(Inherited from Activity)
ToString()

Returns a String that contains the Id and DisplayName of the Activity.

(Inherited from Activity)
UpdateInstance(NativeActivityUpdateContext)

Updates the instance of NativeActivity.

(Inherited from NativeActivity)
