ObjectDataSource.Insert Method ()


Performs an insert operation by calling the method that is identified by the InsertMethod property and any parameters in the InsertParameters collection.

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

Public Function Insert As Integer

Return Value

Type: System.Int32

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

Before the Insert operation is performed, the OnInserting method is called to raise the Inserting event. You can handle the Inserting event to examine the values of the parameters and to perform any preprocessing before an Insert operation. To perform an insert operation, the ObjectDataSourceView object uses reflection to create an instance of the object that is identified by the TypeName property. It then calls the method that is identified by the InsertMethod property, using any associated InsertParameters properties. After the Insert operation completes, the OnInserted method is called to raise the Inserted event. You can handle the Inserted event to examine any return values, output parameters, and exceptions, and to perform any post-processing.

The Insert method delegates to the Insert method of the ObjectDataSourceView that is associated with the ObjectDataSource control.

For more information about parameter merging, object lifetime, and method resolution, see InsertMethod.

When the ObjectDataSource object is associated with a data-bound control, such as the GridView control, it is not necessary to call the Insert method from page code. The Insert method is invoked directly by the data-bound control instead.
