Data binding directly to a store query (DbSet DbQuery DbSqlQuery) is not supported

how solve this problam

 Data binding directly to a store query (DbSet, DbQuery, DbSqlQuery) is not supported. Instead populate a DbSet with data, for example by calling Load on the DbSet, and then bind to local data. For WPF bind to DbSet.Local. For WinForms bind to DbSet.Local.ToBindingList().

 protected void Page_Load(object sender, EventArgs e)
    {
        testEntities MyDB = new testEntities();
       GridView1.DataSource = from P in MyDB.T2
       select new { P.age, P.id, P.number };
        GridView1.DataBind();

    
        
    }
