Exceptions

Exception	Condition
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.

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.

Examples

The following code example adds a new item to the list with the AddNew method.

Visual Basic

Private Sub AddListItem()
    ' Get the CurrencyManager for a DataTable.
    Dim myCurrencyManager As CurrencyManager = _ 
        CType(Me.BindingContext(DataTable1), CurrencyManager)
    myCurrencyManager.AddNew()
End Sub 'AddListItem

private void AddListItem()
{
   // Get the CurrencyManager for a DataTable.
   CurrencyManager myCurrencyManager = 
   (CurrencyManager)this.BindingContext[DataTable1];
   myCurrencyManager.AddNew();
}

Visual C++

void AddListItem()
{

   // Get the CurrencyManager for a DataTable.
   CurrencyManager^ myCurrencyManager = dynamic_cast<CurrencyManager^>(this->BindingContext[ DataTable1 ]);
   myCurrencyManager->AddNew();
}

JScript

private function AddListItem()
{
   // Get the CurrencyManager for a DataTable.
   var myCurrencyManager : CurrencyManager = 
   CurrencyManager(this.BindingContext[DataTable1]);
   myCurrencyManager.AddNew();
}
