Web Forms :: Using Value From SqlDataSource To Show / Hide Element?

I am in the process of re-developing my website into ASP.NET from a product called LogiXML. My background is in front end design using XHTML, CSS and Javascript with a good understanding of SQL so this is a HUGE leap for me.

In one of my Views I have created an asp data source to count the number of scheduled meetings:

<asp:SqlDataSource
ID="CountRS"
runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString
%>"
SelectCommand="
SELECT count(*) as countRS
FROM WebMeeting_Calendar
WHERE MeetingDate > getdate()
and MeetingType = 2
">
</asp:SqlDataSource>

Next, I created an asp panel where I wanted to control the "Visible" element by the value returned in the data source but even when using a simple 1 = 0 (to return False) is not working for me.... Basically, if the count of meetings is zero, I don't want the panel to show.

<asp:Panel
ID="Panel1"
runat="server" Visible="<%# 1 = 0
%>"
>
</asp:Panel>
