ASP.Net/C# - Drop down list error

This error is kind of irritating me for three hrs.Please suggest what is wrong in my code which throws this error

DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'startvalue'.




<aspropDownList ID="ddlfmstarttime" runat="server"
DataSourceID="sqlfmstarttime" DataTextField="StartTime"
DataValueField="StartValue" SelectedValue='<%# Bind("startvalue") %>'>
</aspropDownList>


<asp:SqlDataSource ID="sqlfmstarttime" runat="server"
ConnectionString="<%$ ConnectionStrings:custConnectionString %>" SelectCommand="SELECT [starttime],[startvalue] FROM tblTimeFrom

order by startvalue">
<SelectParameters>
<asp:ControlParameter ControlID="lblquerystring" Name="custtid"
PropertyName="Text" />
</SelectParameters>
</asp:SqlDataSource>

Try to set the SelectCommand to : SELECT starttime,startvalue FROM tblTimeFrom
order by startvalue


<asp:SqlDataSource ID="sqlfmstarttime" runat="server"
ConnectionString="<%$ ConnectionStrings:custConnectionString %>" SelectCommand="SELECT starttime,startvalue FROM tblTimeFrom
order by startvalue">
<SelectParameters>
<asp:ControlParameter ControlID="lblquerystring" Name="custtid" PropertyName="Text" />
</SelectParameters>
</asp:SqlDataSource>
