CurrencyManager::AddNew Method ()


Adds a new item to the underlying list.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

virtual void AddNew() override

Exception Condition

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.

This method is supported only if the data source implements the IBindingList interface and the data source allows adding rows (AllowNew is true).


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.

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 ]);
