Event Calendar

I'm trying to modify Munir Shaikh's August 21, 2007, calendar article just a bit to make it an event calendar.  The calendar is populated through a database with short titles in each day's box.  But, when the number is clicked upon, I'd like the details for that day displayed below the calendar.  I thought I had it working, but I'm having trouble.  In the code below, I've done a response.write when the date is passed to the calList_DayRender sub and it appears correct.  Then I wrote it again after it passes within the sub and it appears correct.  I wrote each date from the dataset and they appear to correlate.  Can someone help me?  Many thanks.  (Sorry, it's in vb)

<asp:Calendar ID="calList" runat="server" OnSelectionChanged="chgSelect" />
<asp:label ID="lblDetails" runat="server"  />
