Problem With DataSource Gridview And Bulleted List

 protected void BulletedList1_Click(object sender, BulletedListEventArgs e)
{
TabContainer1.Visible = true;
pnlClientChosen.Visible = true;
pnlNewClient.Visible = false;
ListItem li = BulletedList1.Items[e.Index];

} I have a bulleted list tied to a table, and on click the selectedValue of the bulleted list populates a datagrid.  Heres my code: 

 <asp:BulletedList ID="BulletedList1" runat="server" BulletStyle="Disc" DataSourceID="SqlDataSource1"
DataTextField="LNAME" DataValueField="DEM_ID" DisplayMode="LinkButton" OnClick="BulletedList1_Click">
</asp:BulletedList>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:csAHECData %>"
SelectCommand="SELECT [LNAME], [FNAME], [MNAME], [DEM_ID] FROM [Demog_TOB] ORDER BY [LNAME], [FNAME], [MNAME]">
</asp:SqlDataSource>

 And then for the datagrid: 

  <asp:Panel ID="pnlClientChosen" runat="server">
<asp:GridView ID="GridView1" runat="server" DataSourceID="SqlDataSource2">
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:csAHECData %>"
SelectCommand="SELECT [DEM_ID], [LNAME], [FNAME], [MNAME], [ADDR1], [ADDR2], [CITY], [STATE], [ZIPCODE], [COUNTY], [Gender] FROM [Demog_TOB] WHERE ([DEM_ID] = @DEM_ID)">
<SelectParameters>
<asp:ControlParameter ControlID="BulletedList1" Name="DEM_ID" PropertyName="SelectedValue"
Type="Int64" />
</SelectParameters>
</asp:SqlDataSource>
</asp:Panel>

 

On Bulleted list select I have this code: 

 

 protected void BulletedList1_Click(object sender, BulletedListEventArgs e)
{
TabContainer1.Visible = true;
pnlClientChosen.Visible = true;
ListItem li = BulletedList1.Items[e.Index];

}

 I have no idea whats wrong but when I click on the bulleted list , the pnlClientChosen becomes visible (which contains the data gridview); but there is no gridview available.  There isn't even column names.  One thing that struck me as odd is when I created the datasource and I created the Where statement, when I selected control as ""Where Dem_ID = a control" and I set the control to bulletedlist1, there were three listings for bulletedlist1.  In fact, there were three listings for each control on this page. 

Thanks in advance, I hope I explained this well but I'm in a hurry right now.
