Calendar control in formview

[trubble]

Hi

I've been googling for AGES but still no joy so would really appreciate help!!

I have a form view with a calendar control in it's edit item template. It displays the date from the database correctly, but when I select a different date it:
1) closes the edit template without updating and
2) doesn't update the record (because it's closing the template too early?)

here's my markup:
<asp:FormView ID="fvMeet" runat="server" DataKeyNames="Code" DataSourceID="dsMeetingById">
<EditItemTemplate>
MeetingDate:
<asp:Calendar ID="Calendar2" runat="server" SelectedDate='<%# CType(Eval("MeetingDate"), DateTime).Date %>'
VisibleDate='<%# CType(Eval("MeetingDate"), DateTime).Date %>'></asp:Calendar>
<br />

<asp:LinkButton ID="UpdateButton" runat="server" CausesValidation="True" CommandName="Update"
Text="Update" CssClass="linkbutton" EnableViewState="False"></asp:LinkButton>
<asp:LinkButton ID="UpdateCancelButton" runat="server" CausesValidation="False" CommandName="Cancel"
Text="Cancel" EnableViewState="False" CssClass="linkbutton"></asp:LinkButton>
</EditItemTemplate>

.....

i have also tried with

SelectedDate='<%# Bind("MeetingDate") %>'
VisibleDate='<%# Eval("MeetingDate") %>'

but no joy
:(
