Parâmetros

insertLocation
HitTestInfo

O local no designer para inserir as atividades.

activitiesToInsert
ReadOnlyCollection<Activity>

A lista de atividades a ser inserida.

Comentários

Use InsertActivities para inserir uma lista de atividades no local especificado.

Antes de chamar InsertActivities, use CanInsertActivities para garantir que as atividades especificadas possam ser inseridas.

Aplica-se a

InsertActivities(CompositeActivityDesigner, HitTestInfo, ReadOnlyCollection<Activity>, String)

Insere atividades no designer no local especificado usando uma transação.

Public Shared Sub InsertActivities (compositeActivityDesigner As CompositeActivityDesigner, insertLocation As HitTestInfo, activitiesToInsert As ReadOnlyCollection(Of Activity), undoTransactionDescription As String)

Parâmetros

compositeActivityDesigner
CompositeActivityDesigner

O designer no qual as atividades serão inseridas.

insertLocation
HitTestInfo

O local no designer no qual as atividades serão inseridas.

undoTransactionDescription
String

Descrição da transação de designer criada pela inserção.

Exemplos

O exemplo a seguir demonstra a adição de um novo branch usando um designer com base na CompositeActivityDesigner classe. Se CanInsertActivities retornar true, um novo branch será criado usando o InsertActivities método.

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
    Return New ParallelIfBranch()
End Function

Private Sub OnAddBranch(ByVal sender As Object, ByVal e As EventArgs)
    Dim activity1 As CompositeActivity = Me.OnCreateNewBranch()
    Dim activity2 As CompositeActivity = CType(MyBase.Activity, CompositeActivity)

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

        Dim num1 As Integer = Me.ContainedDesigners.Count
        Dim activityArray1() As Activity = {activity1}

        If (CanInsertActivities(New ConnectorHitTestInfo(Me, HitTestLocations.Designer, activity2.Activities.Count), _
            New List(Of Activity)(activityArray1).AsReadOnly())) Then

            CompositeActivityDesigner.InsertActivities(Me, _
                New ConnectorHitTestInfo(Me, HitTestLocations.Designer, activity2.Activities.Count), _
                New List(Of Activity)(activityArray1).AsReadOnly(), _
                String.Format("Adding branch 0}", activity1.GetType().Name))

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