CurrencyManager.AddNew Method
Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Adds a new item to the underlying list.
public:
override void AddNew();
public override void AddNew ();
override this.AddNew : unit -> unit
Public Overrides Sub AddNew ()
Exceptions
The underlying data source does not implement IBindingList, or the data source has thrown an exception because the user has attempted to add a row to a read-only or fixed-size DataView.
Examples
The following code example adds a new item to the list with the AddNew method.
void AddListItem()
{
// Get the CurrencyManager for a DataTable.
CurrencyManager^ myCurrencyManager = dynamic_cast<CurrencyManager^>(this->BindingContext[ DataTable1 ]);
myCurrencyManager->AddNew();
}
private void AddListItem()
{
// Get the CurrencyManager for a DataTable.
CurrencyManager myCurrencyManager =
(CurrencyManager)this.BindingContext[DataTable1];
myCurrencyManager.AddNew();
}
Private Sub AddListItem()
' Get the CurrencyManager for a DataTable.
Dim myCurrencyManager As CurrencyManager = _
CType(Me.BindingContext(DataTable1), CurrencyManager)
myCurrencyManager.AddNew()
End Sub
Remarks
This method is supported only if the data source implements the IBindingList interface and the data source allows adding rows (AllowNew is true
).
Note
This property was designed to allow complex-bound controls, such as the DataGrid control, to add new items to list.
You typically use this property only if you are creating your own control that incorporates the CurrencyManager. Otherwise, to add items if the data source is a DataView, use the DataView.AddNew method of the DataView class. If the data source is a DataTable, use the NewRow method and add the row to the DataRowCollection.
