protected:
virtual int ExecuteInsert(System::Collections::IDictionary ^ values);protected virtual int ExecuteInsert (System.Collections.IDictionary values);abstract member ExecuteInsert : System.Collections.IDictionary -> int

- values
- IDictionary
An IDictionary of name/value pairs used during an insert operation.
Returns
The number of items that were inserted into the underlying data storage.
Exceptions
The ExecuteInsert(IDictionary) operation is not supported by the DataSourceView.
Examples
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 override bool CanInsert {
get {
return false;
}
}
protected override int ExecuteInsert(IDictionary values)
{
throw new NotSupportedException();
}
' 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
Remarks
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.
Note
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.
