[Solved] WaterMarkExtender not working for TextBox with TextMode Date in ASP.Net

hi all

I have textbox type date

I want to make watermark for this textbox (To Date)

I use this code

<asp:TextBox ID="txttodate" runat="server" CssClass="auto-style2" Height="30px" TextMode="Date" Width="130px" Enabled="False" ToolTip="To Date" ></asp:TextBox>
<cc1:TextBoxWatermarkExtender ID="txttodate_TextBoxWatermarkExtender" runat="server" TargetControlID="txttodate" WatermarkText="To Date">
</cc1:TextBoxWatermarkExtender>

But It does not work with textbox date type show only dd/MM/yyyy

With it, it works on text-type textbox

Thank you
