EntityDataSource vs Routing

Hello,
Pls would you advise?

I am using routing from hyperlink button. It creates the route for instance "http://localhost:52565/home/1" .

And then I am passing it into entitydatasource.


        ConnectionString="name=WitzenDBEntities"
        DefaultContainerName="WitzenDBEntities" EnableFlattening="False"
        EntitySetName="Witzens" Where="it.TagID == @TagID and it.Approved == true"
         >
       
           
       
   

and the output to the ListView shows nothing.
If I change it into:

        ConnectionString="name=WitzenDBEntities"
        DefaultContainerName="WitzenDBEntities" EnableFlattening="False"
        EntitySetName="Witzens" Where="it.TagID == 1 and it.Approved == true"
         >
       <%--
           
        --%>
   

It works normally and I get the needed filtered output.
Please advice am I missing something?

I also added    DataKeyNames="ID" or  DataKeyNames="TagID"   into ListView.
Route def is:

RouteTable.Routes.MapPageRoute("HomePageFiltered", "home/{TagID}", "~/Pages/HomePage.aspx");

And hyperlink button is:

 

Many Thx
