Provides data for the ItemInserted event.
Assembly: System.Web (in System.Web.dll)
Thetype exposes the following members.
|AffectedRows||Gets the number of rows affected by the insert operation.|
|Exception||Gets the exception (if any) that was raised during the insert operation.|
|ExceptionHandled||Gets or sets a value indicating whether an exception that was raised during the insert operation was handled in the event handler.|
|KeepInInsertMode||Gets or sets a value indicating whether the DetailsView control should remain in insert mode after an insert operation.|
|Values||Gets a dictionary that contains the field name/value pairs for the inserted record.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The DetailsView control raises the ItemInserted event when an Insert button (a button with its CommandName property set to "Insert") within the control is clicked, but after the DetailsView control inserts the record. This allows you to provide an event handler that performs a custom routine, such as checking the results of an insert operation, whenever this event occurs.
A object is passed to the event handler, which allows you to determine the number of records affected and any exceptions that might have occurred. To determine the number of records affected by the insert operation, use the AffectedRows property. Use the Exception property to determine whether any exceptions occurred. You can also indicate whether the exception was handled in the event handler by setting the ExceptionHandled property. If you need to access the values of the inserted record, use the Values property.
By default, the DetailsView control returns to the mode specified by the DefaultMode property after an insert operation. To keep the DetailsView control in insert mode, set the KeepInInsertMode property to true.
For more information about handling events, see Consuming Events.
The following code example demonstrates how to use the object passed to the event handler for the ItemInserted event to determine whether an exception occurred during an insert operation.
