通过

ParallelActivityDesigner.CanMoveActivities 方法

  • 参考

定义

命名空间:
System.Workflow.ComponentModel.Design
程序集:
System.Workflow.ComponentModel.dll

返回一个值，该值指示能否移动与 ParallelActivityDesigner 关联的活动的子活动。

public:
 override bool CanMoveActivities(System::Workflow::ComponentModel::Design::HitTestInfo ^ moveLocation, System::Collections::ObjectModel::ReadOnlyCollection<System::Workflow::ComponentModel::Activity ^> ^ activitiesToMove);
public override bool CanMoveActivities (System.Workflow.ComponentModel.Design.HitTestInfo moveLocation, System.Collections.ObjectModel.ReadOnlyCollection<System.Workflow.ComponentModel.Activity> activitiesToMove);
override this.CanMoveActivities : System.Workflow.ComponentModel.Design.HitTestInfo * System.Collections.ObjectModel.ReadOnlyCollection<System.Workflow.ComponentModel.Activity> -> bool
Public Overrides Function CanMoveActivities (moveLocation As HitTestInfo, activitiesToMove As ReadOnlyCollection(Of Activity)) As Boolean

参数

moveLocation
HitTestInfo

描述要将活动移动到的位置的 HitTestInfo。

activitiesToMove
ReadOnlyCollection<Activity>

包含要移动的活动的 Activity 只读集合。

返回

Boolean

如果可以在父活动中移动活动，则为 true；否则为 false。

示例

下面的示例演示如何重写 CanMoveActivities 方法，以便允许在 ParallelActivityDesigner 内移动子活动。

public override bool CanMoveActivities(HitTestInfo moveLocation, ReadOnlyCollection<Activity> activitiesToMove)
{
    return false;
}

Public Overrides Function CanMoveActivities(ByVal moveLocation As HitTestInfo, ByVal activitiesToMove As ReadOnlyCollection(Of Activity)) As Boolean
    Return False
End Function
