HierarchicalDataBoundControlDesigner.GetDesignTimeDataSource 方法
定义
获取一个设计时使用的关联控件的数据源。Gets a data source that can be used at design time for the associated control.
protected:
virtual System::Web::UI::IHierarchicalEnumerable ^ GetDesignTimeDataSource();
protected virtual System.Web.UI.IHierarchicalEnumerable GetDesignTimeDataSource ();
abstract member GetDesignTimeDataSource : unit -> System.Web.UI.IHierarchicalEnumerable
override this.GetDesignTimeDataSource : unit -> System.Web.UI.IHierarchicalEnumerable
Protected Overridable Function GetDesignTimeDataSource () As IHierarchicalEnumerable
返回
实现 IHierarchicalEnumerable 接口的对象,可用作 HierarchicalDataBoundControl 派生的控件的数据源。An object implementing the IHierarchicalEnumerable interface that can be used as a data source for controls derived from the HierarchicalDataBoundControl.
注解
出于性能原因,最好在设计时使用简单的预定义数据源,而不是从类派生的控件的实际数据源 HierarchicalDataBoundControl 。For performance reasons, it is better to use a simple predefined data source at design time rather than the actual data source for the control that is derived from the HierarchicalDataBoundControl class.
