ListBox not validating with RequiredFieldValidator

Why is the following code not validating?? I thought if I set InitialValue="0" then it would throw an error if 'Please Select' or none of the items are selected?? Is there something I need to add??

<table>
<tr>
<td>
Hobbies & Interests:<br />
<asp:ListBox ID="ddlInterests" runat="server" SelectionMode="Multiple"
DataSourceID="SqlDataSource3" DataTextField="Interests_Desc"
DataValueField="Interests_ID" AppendDataBoundItems="True">
<asp:ListItem Value="0">-- Please select --</asp:ListItem>
</asp:ListBox>

<asp:RequiredFieldValidator ID="rfvInterests" runat="server" Display="Dynamic" InitialValue="0"
ControlToValidate="ddlInterests" ErrorMessage="Please select at least one hobby/interest"></asp:RequiredFieldValidator>
</div>
<asp:SqlDataSource ID="SqlDataSource3" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
SelectCommand="spGetInterests" SelectCommandType="StoredProcedure">
</asp:SqlDataSource>
</td>
<tr>
<td align="right">
<asp:Button class="btnDefault" ID="btnSubmit" runat="server" CausesValidation="True" onclick="searchSkillset" Text="Search" />
</td> </tr>
</table>

Try setting InitialValue of your validator to "" instead of "0"

why do you need

<asp:ListItem Value="0">-- Please select --</asp:ListItem>

in your ListBox?

Btw, your code worked for me without an issue
