Question

I have a gridview that displays all trips – within that gridview I have a repeater that displays the countries visited during that trip (one to many). My repeater is suppose to grap the tripID and then populate the datasource, which populates the repeater. Unfortunately, my repeater is just being populated with the last tripID specified.

  <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="pkiTripID"
                    DataSourceID="SqlDataSource2" PageSize="20" AllowPaging="True" 
                    Width="100%" AllowSorting="True"
                    GridLines="None" onrowdatabound="GridView1_RowDataBound1">                 
                    <Columns>
                        <asp:BoundField DataField="TripType1" HeaderText="Type" SortExpression="TripType1" />
                        <asp:BoundField DataField="RegionName" HeaderText="Region" SortExpression="RegionName" />
                        <asp:TemplateField HeaderText="Country" HeaderStyle-ForeColor="#FF7900">
                            <ItemTemplate>
                                <asp:Repeater ID="RepeatCountry" runat="server"  
                                    DataSourceID="dsCountryByTripID" onitemdatabound="RepeatCountry_ItemDataBound">
                                    <ItemTemplate>
                                        <%# DataBinder.Eval(Container.DataItem, "CountryName") %>
                                    </ItemTemplate>
                                </asp:Repeater>
                            </ItemTemplate>
                            <HeaderStyle ForeColor="#FF7900" />
                        </asp:TemplateField>
                        <asp:BoundField DataField="OverallRating" HeaderText="Trip Rating" 
                            SortExpression="OverallRating" />
                        <asp:BoundField DataField="DepartureDate" HeaderText="Date" SortExpression="DepartureDate"
                            DataFormatString="{0:MMM-dd-yyyy}" HtmlEncode="false" />
                    </Columns>
                </asp:GridView> 

 <asp:SqlDataSource ID="dsCountryByTripID" runat="server" 
        ConnectionString="<%$ ConnectionStrings:myDB %>" 
        SelectCommand="spSelectCountriesByTripID" SelectCommandType="StoredProcedure">
        <SelectParameters>
        <asp:Parameter Type="Int32" Name="tripID"  DefaultValue="96" />
        </SelectParameters>
    </asp:SqlDataSource>

And my code behind

  protected void GridView1_RowDataBound1(object sender, GridViewRowEventArgs e)
    {
        Repeater rp = (Repeater)e.Row.FindControl("RepeatCountry");

        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            dsCountryByTripID.SelectParameters.Clear();
            DataRowView drv = (DataRowView)e.Row.DataItem;
            string tripID = (drv["pkiTripId"]).ToString();
            dsCountryByTripID.SelectParameters.Clear();
            dsCountryByTripID.SelectParameters.Add("tripID", DbType.Int32, tripID);
            ////gv2.DataBind();
            //e.Row.DataBind();

        }
    }
    protected void RepeatCountry_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        e.Item.DataBind();
    }

Answer 1

I decided not to use DataSource and use my own, I gave me more flexibility to bind the repeater(no need for gridview) within the gridview, before moving to the next row.
