CompositeActivityDesigner.CanInsertActivities 方法

定義

傳回值,這個值會指出是否可將活動插入到與設計工具相關聯的複合活動中。

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

參數

insertLocation
HitTestInfo

要插入活動的位置。

activitiesToInsert
ReadOnlyCollection<Activity>

要插入的 Activity 唯讀陣列。

傳回

Boolean

如果可以將活動插入到與設計工具關聯的複合活動則為 true,否則為 false

範例

下列範例將示範如何藉由禁止插入子活動來鎖定 CompositeActivityDesigner

public override bool CanInsertActivities(HitTestInfo insertLocation, ReadOnlyCollection<Activity> activitiesToInsert)
{
    return false;
}
Public Overrides Function CanInsertActivities(ByVal insertLocation As HitTestInfo, ByVal activitiesToInsert As ReadOnlyCollection(Of Activity)) As Boolean
    Return False
End Function

備註

您可以使用 CanInsertActivities 決定是否可將活動清單插入到複合活動中。
