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

Inserts activities into the designer at the specified location using a transaction.

InsertActivities(HitTestInfo, ReadOnlyCollection<Activity>)

Inserts the specified activities in the designer at the specified location.

public:
 virtual void InsertActivities(System::Workflow::ComponentModel::Design::HitTestInfo ^ insertLocation, System::Collections::ObjectModel::ReadOnlyCollection<System::Workflow::ComponentModel::Activity ^> ^ activitiesToInsert);
public virtual void InsertActivities (System.Workflow.ComponentModel.Design.HitTestInfo insertLocation, System.Collections.ObjectModel.ReadOnlyCollection<System.Workflow.ComponentModel.Activity> activitiesToInsert);
abstract member InsertActivities : System.Workflow.ComponentModel.Design.HitTestInfo * System.Collections.ObjectModel.ReadOnlyCollection<System.Workflow.ComponentModel.Activity> -> unit
override this.InsertActivities : System.Workflow.ComponentModel.Design.HitTestInfo * System.Collections.ObjectModel.ReadOnlyCollection<System.Workflow.ComponentModel.Activity> -> unit
Public Overridable Sub InsertActivities (insertLocation As HitTestInfo, activitiesToInsert As ReadOnlyCollection(Of Activity))

Parameters

insertLocation
HitTestInfo

The location in the designer to insert the activities.

ReadOnlyCollection<Activity>

The list of activities to insert.

Remarks

Use InsertActivities to insert a list of activities into the location specified.

Prior to calling InsertActivities, use CanInsertActivities to make sure that the specified activities can be inserted.

Applies to

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

Inserts activities into the designer at the specified location using a transaction.

public:
 static void InsertActivities(System::Workflow::ComponentModel::Design::CompositeActivityDesigner ^ compositeActivityDesigner, System::Workflow::ComponentModel::Design::HitTestInfo ^ insertLocation, System::Collections::ObjectModel::ReadOnlyCollection<System::Workflow::ComponentModel::Activity ^> ^ activitiesToInsert, System::String ^ undoTransactionDescription);

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

Parameters

compositeActivityDesigner
CompositeActivityDesigner

The designer into which the activities will be inserted.

insertLocation
HitTestInfo

The location in the designer at which the activities will be inserted.

activitiesToInsert
ReadOnlyCollection<Activity>

The list of activities to insert.

undoTransactionDescription
String

Description for the designer transaction created by the insertion.

Examples

The following example demonstrates the addition of a new branch using a designer based off of the CompositeActivityDesigner class. If CanInsertActivities returns true, a new branch is created using the InsertActivities method.

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

Remarks

Use InsertActivities to insert a list of activities into the composite activity.

Prior to calling InsertActivities, use CanInsertActivities to make sure the specified list of activities can be inserted.
