Problem with MaskedEdit from Ajax Control Toolkit - different culture - asp.net

Question

I want to use maskededit to make the user to do the same as in the ajax control toolkit sample for maskededit, but I need to use another format, since dates at my client is displayed as dd-MM-yyyy. I also need to put a value in there to begin with, since the date is loaded from a db (once I get this code working, that is)
Look at this sample:
http://www.asp.net/ajax/ajaxcontroltoolkit/samples/maskededit/maskededit.aspx
I need to do the same as in the textbox labeled "Enter Date (format: 99/99/9999): "
I downloaded the sample code and changed the format to "99-99-9999" in the relevant code:
But the sample date "12-12-1999" is not displayed in the textbox. Why not?
I cant figure out, what I am doing wrong. I also tried setting the cultureName to da-DK, but it did not chance anything. I also tried Chrome, Firefox and IE7, same behaviour...
How do I fix this?
<asp:TextBox ID="TextBox5" runat="server" Width="130px" MaxLength="1" style="text-align:justify" ValidationGroup="MKE">12-12-1999</asp:TextBox>
<asp:ImageButton ID="ImgBntCalc" runat="server" ImageUrl="~/images/Calendar_scheduleHS.png" CausesValidation="False" />
<ajaxToolkit:MaskedEditExtender ID="MaskedEditExtender5" runat="server"
TargetControlID="TextBox5"
Mask="99-99-9999"
MessageValidatorTip="true"
OnFocusCssClass="MaskedEditFocus"
OnInvalidCssClass="MaskedEditError"
MaskType="Date"
DisplayMoney="Left"
AcceptNegative="Left"
ErrorTooltipEnabled="True" />
<ajaxToolkit:MaskedEditValidator ID="MaskedEditValidator5" runat="server"
ControlExtender="MaskedEditExtender5"
ControlToValidate="TextBox5"
EmptyValueMessage="Date is required"
InvalidValueMessage="Date is invalid"
Display="Dynamic"
TooltipMessage="Input a date"
EmptyValueBlurredText="*"
InvalidValueBlurredMessage="*"
ValidationGroup="MKE" />

I suposse you'll have this already fixed, but ... have you tried using UserDateFormat="DayMonthYear" ?
UserDateFormat="DayMonthYear"
<asp:TextBox ID="TextBox5" runat="server" Width="130px" MaxLength="1" style="text-align:justify" ValidationGroup="MKE">12-12-1999</asp:TextBox>
<asp:ImageButton ID="ImgBntCalc" runat="server" ImageUrl="~/images/Calendar_scheduleHS.png" CausesValidation="False" />
<ajaxToolkit:MaskedEditExtender ID="MaskedEditExtender5" runat="server"
TargetControlID="TextBox5"
Mask="99-99-9999"
MessageValidatorTip="true"
OnFocusCssClass="MaskedEditFocus"
OnInvalidCssClass="MaskedEditError"
MaskType="Date"
DisplayMoney="Left"
AcceptNegative="Left"
ErrorTooltipEnabled="True" **UserDateFormat="DayMonthYear"** />
<ajaxToolkit:MaskedEditValidator ID="MaskedEditValidator5" runat="server"
ControlExtender="MaskedEditExtender5"
ControlToValidate="TextBox5"
EmptyValueMessage="Date is required"
InvalidValueMessage="Date is invalid"
Display="Dynamic"
TooltipMessage="Input a date"
EmptyValueBlurredText="*"
InvalidValueBlurredMessage="*"
ValidationGroup="MKE" />

I use ValidationExpression in MaskedEditValidator replace userDateFormat type Date dd/MM/yyy is very good.
This is :
ValidationExpression="(((((0[1-9])|(1\d)|(2[0-8]))\/((0[1-9])|(1[0-2])))|((31\/((0[13578])|(1[02])))|((29|30)\/((0[1,3-9])|(1[0-2])))))\/((20[0-9][0-9])|(19[0-9][0-9])))|((29\/02\/(19|20)(([02468][048])|([13579][26]))))"
And in MaskedEditExtender put MaskType="none".
Validate ok.

<asp:TextBox ID="TextBox5" runat="server" Width="130px" MaxLength="10" style="text-align:justify" ValidationGroup="MKE" Text="12-12-1999"></asp:TextBox>
I am wondering if you move the text to the actual text attribute, if that would make a difference... I don't have the most recent version of AjaxToolkit other wise I would try it my self... Oh I just noticed is your max length really set to one or is that a copy and paste error? That would cause problems too.
