Calender/TextBox history

How do I turn off the display of recently entered data in a TextBox with or without a calendar extender?  When I click in the TextBox it displays recent dates on top of the calendar. Very annoying.  Below is a sample of the markup. NOTE: It seems to only happen in Chrome.

<asp:TextBox ID="txtInvoiceDate" runat="server" Width="76" onchange="invchg();" 
                            AutoCompleteType="None"></asp:TextBox><asp:CalendarExtender ID="CalendarExtender1" runat="server" TargetControlID="txtInvoiceDate"></asp:CalendarExtender><asp:CompareValidator ID="CompareValidator1" runat="server" ErrorMessage="Invoice Date must be a valid date" 
	                        Operator="DataTypeCheck" Type="Date" ControlToValidate="txtInvoiceDate" Display="Dynamic"></asp:CompareValidator><asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server" Display="Dynamic"
                                ErrorMessage="Invoice Date is required" ControlToValidate="txtInvoiceDate"></asp:RequiredFieldValidator>
