   CurrencyManager^ myCurrencyManager = dynamic_cast<CurrencyManager^>(textBox1->BindingContext[nullptr]);

   if ( myCurrencyManager->Count > 1 )

    myCurrencyManager.RemoveAt(0);
}
Private Sub RemoveFromList()
    ' Get the CurrencyManager of a TextBox control.
    Dim myCurrencyManager As CurrencyManager = CType(textBox1.BindingContext(0), CurrencyManager)
    ' If the count is 0, exit the function.
    If myCurrencyManager.Count > 1 Then
        myCurrencyManager.RemoveAt(0)
    End If
    
End Sub

Remarks

The RemoveAt method was designed to allow complex controls, such as the DataGrid control, to remove items from the list. You should not use this method to actually remove items. Instead, use the Delete method of the DataView class to delete items.
