SqlDataSourceView.OnInserted Method

Raises the Inserted event after the SqlDataSource control has completed an insert operation.

Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)

protected:
virtual void OnInserted (
	SqlDataSourceStatusEventArgs^ e
)
protected void OnInserted (
	SqlDataSourceStatusEventArgs e
)
protected function OnInserted (
	e : SqlDataSourceStatusEventArgs
)
Not applicable.

Parameters

e

A SqlDataSourceStatusEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate. For more information, see Consuming Events.

The OnInserted method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors: When overriding the OnInserted method in a derived class, be sure to call the OnInserted method for the base class so that registered delegates receive the event.

The following code example demonstrates how to retrieve data from Microsoft SQL Server, display it in a GridView control, and use a DetailsView control to see details of a selected row in the GridView and as a form to insert new records.

Initially, the data is displayed in the GridView control and the selected row of the GridView is also displayed in the DetailsView control. The GridView and DetailsView controls use different data source controls; the one that is associated with the DetailsView has the FilterExpression and FilterParameters properties, which ensure that the selected row of the GridView is displayed.

If you click the automatically generated Insert button of the DetailsView control, the DetailsView shows a different user interface, which is used to insert a new record. The example uses a stored procedure to insert records and returns the primary key of the inserted row. If you insert a record, the DetailsView automatically populates the InsertParameters collection with values from the bound columns and calls the Insert method. The DetailsView can infer the correct parameters from any BoundField object and a parameter for the TemplateField object when the ASP.NET two-way data-binding syntax is used. In this example, an additional parameter is added in the OnInserting event handler to handle the primary key that is returned by the stored procedure.

Finally, after data is inserted by the DetailsView control into the database, the OnInserted event handler is called to handle the Inserted event, the value of the primary key of the inserted row is displayed, and the DataBind method of the GridView control is called explicitly to refresh the data.
