Utilice InsertActivities para insertar una lista de actividades en la ubicación especificada.

Antes de llamar a InsertActivities, utilice CanInsertActivities para asegurarse de que se pueden insertar las actividades especificadas.

Ejemplos

El ejemplo siguiente muestra la suma de una nueva bifurcación utilizando un diseñador basado fuera de de la clase CompositeActivityDesigner. Si CanInsertActivities devuelve verdadero, una nueva bifurcación se crea utilizando el método InsertActivities.

protected override CompositeActivity OnCreateNewBranch()
{
    return new ParallelIfBranch();
}

private void OnAddBranch(object sender, EventArgs e)
{
    CompositeActivity activity1 = this.OnCreateNewBranch();
    CompositeActivity activity2 = base.Activity as CompositeActivity;

    if ((activity2 != null) && (activity1 != null))
    {
        int num1 = this.ContainedDesigners.Count;
        Activity[] activityArray1 = new Activity[] { activity1 };

        if (CanInsertActivities(new ConnectorHitTestInfo(this, HitTestLocations.Designer, activity2.Activities.Count),
            new List<Activity>(activityArray1).AsReadOnly()))
        {
            CompositeActivityDesigner.InsertActivities(this,
                new ConnectorHitTestInfo(this, HitTestLocations.Designer, activity2.Activities.Count),
                new List<Activity>(activityArray1).AsReadOnly(),
                string.Format("Adding branch {0}", activity1.GetType().Name));

            if ((this.ContainedDesigners.Count > num1) && (this.ContainedDesigners.Count > 0))
            {
                this.ContainedDesigners[this.ContainedDesigners.Count - 1].EnsureVisible();
            }
        }
    }
}

Protected Overrides Function OnCreateNewBranch() As CompositeActivity

    If (activity2 IsNot Nothing) And (activity1 IsNot Nothing) Then

            If (Me.ContainedDesigners.Count > num1) And (Me.ContainedDesigners.Count > 0) Then
                Me.ContainedDesigners(Me.ContainedDesigners.Count - 1).EnsureVisible()
            End If

Utilice InsertActivities para insertar una lista de actividades en la actividad compuesta.

Antes de llamar a InsertActivities, utilice CanInsertActivities para asegurarse de que se puede insertar la lista actividades especificada.
