DataSourceView.ExecuteInsert Method

Performs an insert operation on the list of data that the DataSourceView object represents.

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

'Declaration
Protected Overridable Function ExecuteInsert ( _
	values As IDictionary _
) As Integer

Parameters

values
Type: System.Collections.IDictionary

An IDictionary of name/value pairs used during an insert operation.

Return Value

Type: System.Int32
The number of items that were inserted into the underlying data storage.

ExceptionCondition
NotSupportedException

The ExecuteInsert operation is not supported by the DataSourceView.

Data-bound controls can determine whether the ExecuteInsert operation is supported by a data source control by retrieving the DataSourceView object using the GetView method, and checking the CanInsert property.

The values parameter is a set of name/value pairs that represents data columns or fields and corresponding values to insert.

NoteNote

The DataSourceView class's default implementation is to throw a NotSupportedException exception. If you extend the DataSourceView class, override the ExecuteInsert method if your class supports insertion into the underlying data storage.

The following code example demonstrates how a class that extends the DataSourceView class can override the CanInsert property and the ExecuteInsert method. This code example is part of a larger example provided for the DataSourceView class.

' The CsvDataSourceView does not currently 
' permit insertion of a new record. You can 
' modify or extend this sample to do so. 
Public Overrides ReadOnly Property CanInsert() As Boolean 
   Get 
      Return False 
   End Get 
End Property 

Protected Overrides Function ExecuteInsert(values As IDictionary) As Integer 
   Throw New NotSupportedException()
End Function 'ExecuteInsert
