[C#] LinqDataSource by using FK to Get data, using two tables

Description: I want to show Table1 through PK2.

DB ERD:

(Table1,PK1)----(Relation_Table2_has_Table1, contained the Primary Key of Table1,Table2)----(Table2,PK2)

ASP.Net Code:

<asp:linqdatasource id="LinqDataSource1" runat="server" contexttypename="LinQDataContext" enableupdate="True" entitytypename="" tablename="Table1" where="Relation_Table2_has_Table1.Any(PK2==@data)">
    <whereparameters>
        <asp:sessionparameter name="data" sessionfield="data" type="String" />
    </whereparameters>
</asp:linqdatasource>

If @data is Int, then PK2==Int32?(@data)
