ConditionedActivityGroup Class

Provides the definition of a constraint-based execution context for a set of child activities.

Namespace: System.Workflow.Activities
Assembly: System.Workflow.Activities (in System.Workflow.Activities.dll)

Syntax

Visual Basic (Declaration)

<ToolboxBitmapAttribute(GetType(ConditionedActivityGroup), "Resources.cag.png")> _
<WorkflowDebuggerSteppingAttribute(WorkflowDebuggerSteppingOption.Concurrent)> _
Public NotInheritable Class ConditionedActivityGroup _
    Inherits CompositeActivity _
    Implements IActivityEventListener(Of ActivityExecutionStatusChangedEventArgs)

Visual Basic (Usage)

Dim instance As ConditionedActivityGroup

[ToolboxBitmapAttribute(typeof(ConditionedActivityGroup), "Resources.cag.png")]
[WorkflowDebuggerSteppingAttribute(WorkflowDebuggerSteppingOption.Concurrent)]
public sealed class ConditionedActivityGroup : CompositeActivity, 
    IActivityEventListener<ActivityExecutionStatusChangedEventArgs>

Visual C++

[ToolboxBitmapAttribute(typeof(ConditionedActivityGroup), L"Resources.cag.png")]
[WorkflowDebuggerSteppingAttribute(WorkflowDebuggerSteppingOption::Concurrent)]
public ref class ConditionedActivityGroup sealed : public CompositeActivity, 
    IActivityEventListener<ActivityExecutionStatusChangedEventArgs^>

JScript

public final class ConditionedActivityGroup extends CompositeActivity implements IActivityEventListener<ActivityExecutionStatusChangedEventArgs>

Remarks

The ConditionedActivityGroup activity is a CompositeActivity, meaning the ConditionedActivityGroup activity can contain other activities.

The ConditionedActivityGroup activity runs and re-executes child activities based on the evaluation of their when conditions. All rules are evaluated whenever required based on their data and state change dependencies.

When the completion rule of the ConditionedActivityGroup evaluates to true, it immediately cancels any currently executing child activities and finishes.
