Insert Method

SqlDataSource.Insert Method

Note: This method is new in the .NET Framework version 2.0.

Performs an insert operation using the InsertCommand SQL string and any parameters that are in the InsertParameters collection.

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

public int Insert ()
public int Insert ()
public function Insert () : int

Return Value

A value that represents the number of rows inserted into the underlying database.

Exception typeCondition

InvalidOperationException

The SqlDataSource cannot establish a connection with the underlying data source.

Before the insert operation is performed, the OnInserting method is called to raise the Inserting event. You can handle this event to examine the values of the parameters and to perform any preprocessing before the Insert operation. To perform an insert operation, the SqlDataSourceView object builds an DbCommand object using the InsertCommand text and any associated InsertParameters properties, and then executes the DbCommand object against the underlying database.

After the operation completes, the OnInserted method is called to raise the Inserted event. You can handle this event to examine any return values and error codes and to perform any post-processing.

The Insert method is provided for programmatic access to the Insert method. If the SqlDataSource control is associated with a data-bound control, the data-bound control automatically calls the Insert method.

The Insert method delegates to the Insert method of the SqlDataSourceView object that is associated with the SqlDataSource control.

  • The following code example demonstrates how to insert data into a database using the SqlDataSource control and a simple Web Forms page. The current data in the Data table is displayed in the DropDownList control. You can add new records by entering values in the TextBox controls, and then clicking the Insert button. When the Insert button is clicked, the specified values are inserted into the database, and then the DropDownList is refreshed.
