3 level relations using Dataset;
===

Normally when making master-detail relationships,we use 

    ds.Relations.Add("Relations", ds.Tables["dt1"].Columns["relatedID"], ds.Tables["dt2"].Columns["relatedID"]);  

and use a DataView to add it to a grid and view it.My question is,how can i create a 3 level relationship using a dataset such as;

    MASTER
    |
    |>>DETAIL
            |
            |>>DETAILS OF THE DETAILS
