MaskedEditExtender date format problem ("yyyy-MM-dd" with cultureName="sv-SE" doesn't work) with calender control
<p>I need to create <code>MaskedEditExtender</code> for Sweden date which uses format "yyyy-MM-dd".</p>

<p>I have the following code below. <code>CalendarExtender</code> doesn't work with current <code>MaskedEditExtender</code>. Also the validation doesn't work properly.</p>

<pre class="lang-xml prettyprint-override"><code>&lt;asp:TextBox ID="txtFSFV"
        MaxLength="100"
        style="width:70px"
        runat="server" /&gt;
&lt;asp:HyperLink ID="hplGetCalendar" 
        NavigateUrl="javascript:void(null)" 
        runat="server"&gt;
        &lt;img src="~/images/calendar.png" runat="server" /&gt;
&lt;/asp:HyperLink&gt;
&lt;ajax:CalendarExtender ID="calFSFV"
        Format="yyyy-MM-dd"
        Animated="false"
        PopupButtonID="hplGetCalendar"
        TargetControlID="txtFSFV"
        runat="server" /&gt;
&lt;ajax:MaskedEditExtender
        ID="maskedFSFV"
        TargetControlID="txtFSFV" 
        Mask="9999-99-99"
        MessageValidatorTip="true" 
        OnFocusCssClass="MaskedEditFocus" 
        OnInvalidCssClass="MaskedEditError"
        MaskType="Date"
        Century="2000"
        CultureName="sv-SE"
        UserDateFormat="YearMonthDay"
        InputDirection="LeftToRight"
        runat="server"/&gt;
&lt;ajax:MaskedEditValidator ID="MaskedEditValidator1" 
        runat="server" 
        ControlExtender="maskedFSFV" 
        ControlToValidate="txtFSFV" 
        InvalidValueMessage="Date is invalid"
        IsValidEmpty="True" /&gt;
</code></pre>

<p>Could anybody tell me how can I create a mask ("yyyy-MM-dd") for sv-SE culture?</p>
