Displaying One Data Record

Hi all, this is a very basic question of diplaying a data.
on my aspx page I have datasource that will return only ONE record.

  <asp:SqlDataSource ID="sdsCategoryName" runat="server" ConnectionString="<%$ ConnectionStrings:KaruselaConnectionString %>"
        SelectCommand="SELECT Title FROM tbh_Categories WHERE CategoryID=@categoryID  ">
        <SelectParameters>
            <asp:QueryStringParameter DefaultValue="-1" Name="CategoryID" QueryStringField="id" Type="int32"/>
        </SelectParameters>
    </asp:SqlDataSource>
 

on the server side I would like to manipulate the title of the page according to the data returned from the query:

 and on the behind code if (!this.IsPostBack && !string.IsNullOrEmpty(this.Request.QueryString["ID"]))
{
DataView dv2 = (DataView)sdsCategoryName.Select(arg);
this.Title = string.Format(this.Title, dv2.Table.Columns[0].ToString());
dv2.Dispose();
}
  of course it doesn't work. my question is this. do we really have to put the query datasource on the client side?and secondly, how can I view the recorsd I recieves from the query?Thanks for the help.
