DataList and SqlDataSource SelectCommand Parameter

Question

Hi,
   In my application, I am using DataList. In Item Template I added One GridView and SqlDataSource to populate data in GridView. DataList having one DataKey field, I want to pass this DataKey Value to the SqlDataSource as Parameter.
 I tried this by Using Following:    

<SelectParameters>

                                                                                <%--<asp:Parameter  DefaultValue="" Name="LocatioID"  DbType="Int32" />--%>

                                                                                <asp:ControlParameter ControlID="dlJobsByLocation" Name="LocatioID" PropertyName="DataKeys[0]" />

                                                                                </SelectParameters>

<SelectParameters>
    <asp:ControlParameter ControlID="dataList" Name="ID" PropertyName="DataKeys[0]" />
</SelectParameters>
In above snippet I hard coded Property Name to DataKeys[0], due to this it return DataKey value of first row only.

    Here I need ProperyName which gives the DataKeys value for every row at the time of ItemDataBound. The Value 0 should be replaced with something  thats where I stuck.......


Any Help Appreciated.........


Thanks,
