IControlAdapter.LoadPostData(String, NameValueCollection, Object, Boolean) 方法
定义
如果适配器处理 post 数据的加载,则返回 true。Returns true if the adapter handles loading the post data. 此 API 已废弃不用。This API is obsolete. 若要了解如何开发 ASP.NET 移动应用,请参阅 Mobile Apps & Sites with ASP.NET (ASP.NET 移动应用和网站)。For information about how to develop ASP.NET mobile applications, see Mobile Apps & Sites with ASP.NET.
public:
bool LoadPostData(System::String ^ postDataKey, System::Collections::Specialized::NameValueCollection ^ postCollection, System::Object ^ controlPrivateData, [Runtime::InteropServices::Out] bool % dataChanged);
public bool LoadPostData (string postDataKey, System.Collections.Specialized.NameValueCollection postCollection, object controlPrivateData, out bool dataChanged);
abstract member LoadPostData : string * System.Collections.Specialized.NameValueCollection * obj * bool -> bool
Public Function LoadPostData (postDataKey As String, postCollection As NameValueCollection, controlPrivateData As Object, ByRef dataChanged As Boolean) As Boolean
参数
- postDataKey
- String
标识控件。Identifies the control.
- postCollection
- NameValueCollection
包含所有传入名称值的集合。Contains the collection of all incoming name values.
- controlPrivateData
- Object
提供一个向控件发送私有数据的位置,加载发送数据时可能必须要用到该控件。Provides a place to send private data to the control that might be required for loading of post data. 该控件确定传递到参数的类型。The control determines the type that is passed to the parameter.
- dataChanged
- Boolean
如果 privateControlData 中所需的对象发生了更改,则返回 true,因此可能引发 RaisePostDataChangedEvent() 事件。Returns true if the required the object in privateControlData was changed, so the RaisePostDataChangedEvent() event can be raised.
返回
如果适配器处理 post 数据的加载,则为 true;否则为 false。true if the adapter handles loading the post data; otherwise, false.
注解
当实现接口的控件 IPostBackDataHandler 具有其自己的方法时,将调用此方法 LoadPostData 。This method is called when a control that implements the IPostBackDataHandler interface has its own LoadPostData method invoked.
备注
不同的设备可能以不同的方式将其数据返回给调用服务器。Different devices might provide their data back to the calling server in different ways. 例如,WML 和 HTML 报告如何返回的结果之间的差异 SelectionList 。An example is the difference between how WML and HTML report back the results of a SelectionList.
