DetailsView.ItemInserted 事件

定义

在单击 DetailsView 控件中的“插入”按钮时,但在插入操作之后发生。Occurs when an Insert button within a DetailsView control is clicked, but after the insert operation.

public:
 event System::Web::UI::WebControls::DetailsViewInsertedEventHandler ^ ItemInserted;
public event System.Web.UI.WebControls.DetailsViewInsertedEventHandler ItemInserted;
member this.ItemInserted : System.Web.UI.WebControls.DetailsViewInsertedEventHandler 
Public Custom Event ItemInserted As DetailsViewInsertedEventHandler 

示例

下面的代码示例演示如何使用ItemInserted事件在DetailsView控件执行插入操作GridView后刷新控件。The following code example demonstrates how to use the ItemInserted event to refresh a GridView control after a DetailsView control performs an insert operation. 这会使GridView控件DetailsView与控件保持同步。This keeps the GridView control synchronized with the DetailsView control.

注解

当单击DetailsView控件中的 "插入" 按钮时, 但在插入操作后引发事件。ItemInsertedThe ItemInserted event is raised when an Insert button within the DetailsView control is clicked, but after the insert operation. 这使您可以提供一个事件处理程序, 以便在每次发生此事件时执行自定义例程, 如检查插入操作的结果。This allows you to provide an event handler that performs a custom routine, such as checking the results of the insert operation, whenever this event occurs.

DetailsViewInsertedEventArgs对象传递到事件处理程序, 该处理程序允许您确定受影响的行数以及可能已发生的任何异常。A DetailsViewInsertedEventArgs object is passed to the event handler, which allows you to determine the number of rows affected and any exceptions that might have occurred. 还可以通过设置ExceptionHandled属性, 指示是否已在事件处理程序中处理异常。You can also indicate whether the exception was handled in the event handler by setting the ExceptionHandled property. 若要在插入操作后使控件处于插入模式, 请将KeepInInsertMode属性设置true为。To keep the control in insert mode after an insert operation, set the KeepInInsertMode property to true.

有关如何处理事件的详细信息, 请参阅处理和引发事件For more information about how to handle events, see Handling and Raising Events.
