Exemplos

void GetCurrentItem()
{
   CurrencyManager^ myCurrencyManager;
   
   // Get the CurrencyManager of a TextBox control.
   myCurrencyManager = dynamic_cast<CurrencyManager^>(textBox1->BindingContext[nullptr]);
   
   // Get the current item cast as a DataRowView.
   DataRowView^ myDataRowView;
   myDataRowView = dynamic_cast<DataRowView^>(myCurrencyManager->Current);
   
   // Print the column named ContactName.
   Console::WriteLine( myDataRowView[ "ContactName" ] );
}

private void GetCurrentItem() {
    CurrencyManager myCurrencyManager;
    // Get the CurrencyManager of a TextBox control.
    myCurrencyManager = (CurrencyManager)textBox1.BindingContext[0];
    // Get the current item cast as a DataRowView.
    DataRowView myDataRowView;
    myDataRowView = (DataRowView) myCurrencyManager.Current;
    // Print the column named ContactName.
    Console.WriteLine(myDataRowView["ContactName"]);
}

Private Sub GetCurrentItem()
    Dim myCurrencyManager As CurrencyManager
    ' Get the CurrencyManager of a TextBox control.
    myCurrencyManager = CType(textBox1.BindingContext(0), CurrencyManager)
    ' Get the current item cast as a DataRowView.
    Dim myDataRowView As DataRowView
    myDataRowView = CType(myCurrencyManager.Current, DataRowView)
    ' Print the column named ContactName.
    Console.WriteLine(myDataRowView("ContactName"))
End Sub

Observações

Para obter o item atual, tens de conhecer o seu tipo de dados para o lançar corretamente. Por exemplo, se a fonte de dados for um DataView ou DataTable, deve lançar o item atual como DataRowView objeto.
