Public Overrides Sub AddNew ()

Exceptions

NotSupportedException

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.
