and
binding code;

C#

private void GrdIskalemiDoldur()
       {

           grdIskalemleri.DataSource = from A in db.eMakbuzIskalemis
                                       //join B in db.eIskalemis
                                       //on A.MIskalemiId equals B.IsKalemiId
                                       //group A by new
                                       //{
                                       //    B.IsKalemiAdi,
                                       //    B.IsKalemiId
                                       //} into E
                                       select new
                                       {
                                           IskalemiAdi = A.IsKalemiBaslikBirimFiyati,
                                           IskalemiId = A.IskalemiBaslikMiktar
                                           //IskalemiAdi = E.Key.IsKalemiAdi,
                                           //IskalemiId = E.Key.IsKalemiId,
                                       };
           grdIskalemleri.DataBind();
       }

Its not problem but I cant this;

C#

 protected void grdIskalemleri_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            string Id = grdIskalemleri.DataKeys[e.Row.RowIndex].Value.ToString();
//my problem is Id is null.but I know It has value
            GridView yeni = e.Row.FindControl("altGrid") as GridView;
//I didnt use Id and my datasource is null.
            yeni.DataSource = from A in db.eMakbuzIskalemis
                              select new {
                                  Deneme=A.IskalemiBaslikMiktar
                              };
            yeni.DataBind();
        }

I need to use nested gridview.

add condition in grdIskalemleri_RowDataBound event before find nested grid inside parent grid.

C#

protected void grdIskalemleri_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                string Id = grdIskalemleri.DataKeys[e.Row.RowIndex].Value.ToString();
                //my problem is Id is null.but I know It has value
                GridView yeni = e.Row.FindControl("altGrid") as GridView;
                //I didnt use Id and my datasource is null.
                yeni.DataSource = from A in db.eMakbuzIskalemis
                                  select new
                                  {
                                      Deneme = A.IskalemiBaslikMiktar
                                  };
                yeni.DataBind();
            }
        }
