BindingManagerBase.PullData 方法

定义

将数据从数据绑定控件拉入到数据源,不返回任何信息。Pulls data from the data-bound control into the data source, returning no information.

protected:
 void PullData();
protected void PullData ();
member this.PullData : unit -> unit
Protected Sub PullData ()

注解

PullData方法是将数据绑定控件中的信息提取回数据源的编程方法。The PullData method is a programmatic way to pull information from the data-bound control back into the data source. 它不是控件的标准操作所必需的,因为当焦点离开时,控件通常会自动更新其绑定数据源。It is not required for standard operation of a control, since normally a control automatically updates its bound data source when focus leaves it.

PullData根据需要,对数据源引发事件和更改事件。BindingCompletePullData raises the BindingComplete event and change events on the data source as appropriate.
