Default Binding IEnumerable result set of a LINQ query

When binding IEnumerable result set of a LINQ query to a nested grid getting ERROR:
NotSupportedException : The data source does not support server-side data paging;
Details are below

Code:
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
  IList<Products> listpdt = (IList < Products >) Session["Product"];
  if (e.Row.RowType == DataControlRowType.DataRow)
  {
     var pdt = from p in listpdt
          where p.ProductName == “Apple”
          select p;
     GridView gdv = (GridView)e.Row.FindControl("GridView2");
     gdv.DataSource = pdt;
     gdv.DataBind();
  }
}

Suppose returns 4 result set of type IEnumerable and I am binding to Gridview which is nested in another Gridview.
