StructuredCompositeActivityDesigner.CanInsertActivities(HitTestInfo, ReadOnlyCollection<Activity>) 方法

定義

傳回值,這個值表示指定的活動是否可加入至工作流程設計介面上指定位置的 StructuredCompositeActivityDesignerReturns a value that indicates whether the specified activities can be added to the StructuredCompositeActivityDesigner at the specified location on the workflow design surface.

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

參數

insertLocation
HitTestInfo

HitTestInfo,其中包含要嘗試插入活動的螢幕位置。The HitTestInfo that contains the screen location at which to attempt to insert the activities.

activitiesToInsert
ReadOnlyCollection<Activity>

Activity 唯讀集合,包含要加入的活動。The Activity read-only collection that contains the activities to add.

傳回

如果可以將指定的活動插入工作流程設計介面上的指定位置則為 true,否則為 falsetrue if the specified activities can be inserted at the specified location on the workflow design surface; otherwise, false.

範例

下列範例將示範如何藉由禁止插入子活動來鎖定 StructuredCompositeActivityDesignerThe following example shows how to lock a StructuredCompositeActivityDesigner by not allowing the insertion of child activities.

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
