ASP.NET แนะนำด้วยค่ะ งงมากมาย ประมาณว่า ต้องการโชว์ค่าในgridview เป็น "Yes" หรือ "No"

         if (Page.Request["sid"] != null)
            {
                string sid = Page.Request["sid"];

                BMItem req = new BMItem();
                oView = new DataView(req.GetAllItemBySubCategoryID(sid));
                oGrid.DataSource = oView;

                Controls.Add(oGrid);

                oGrid.PageSize = 12;
                oGrid.AllowPaging = true;
                oGrid.PagerSettings.Mode = PagerButtons.Numeric;
                oGrid.PagerSettings.Position = PagerPosition.Bottom;
                oGrid.PagerSettings.PageButtonCount = 10;
                oGrid.PageIndexChanging +=
                    new GridViewPageEventHandler(oGrid_PageIndexChanging);
                oGrid.PagerTemplate = null;
                if (ViewState["SortDirection"] != null && ViewState["SortExpression"] != null)
                {

                    oView.Sort = ViewState["SortExpression"].ToString()
                        + " " + ViewState["SortDirection"].ToString();
                }

                oGrid.DataBind();
            }

 public DataTable GetAllItemBySubCategoryID(string sid)
        {
            RMItem ritem = new RMItem();
            return ritem.GetAllItemBySubCategoryID(sid).GetDataTable();

        }
แล้วฟังก์ชันนี้ก็ไปเรียกอีกตัวคือ


 public SPListItemCollection GetAllItemBySubCategoryID(string sid)
        {
            using (SPSite siteCollection = new SPSite(SPContext.Current.Web.Url))
            {
                using (SPWeb mySite = siteCollection.OpenWeb())
                {

                    SPList list = mySite.Lists["M_Item"];

                    SPQuery query = new SPQuery();
                    query.Query = "<Where>"
                                    + "<Eq><FieldRef Name='SubCategoryID'/><Value Type='Text'>" + sid + "</Value></Eq>"
                                    + "</Where>";
                    SPListItemCollection myItems = list.GetItems(query);



                    return myItems;
                }
            }
        }

 public DataTable GetAllItemBySubCategoryID(string sid)
        {
            RMItem ritem = new RMItem();
            // return ritem.GetAllItemBySubCategoryID(sid).GetDataTable();

            using (SPSite siteCollection = new SPSite(SPContext.Current.Web.Url))
            {
                using (SPWeb mySite = siteCollection.OpenWeb())
                {
                    List<M_Item> lists = new List<M_Item>();

                    mySite.AllowUnsafeUpdates = true;
                    SPList list = mySite.Lists["M_Item"];
                    SPListItemCollection myItems = list.Items;
                    foreach (SPListItem item in myItems)
                    {
                        M_Item mitem = new M_Item();
                        mitem.ItemCode = Convert.ToString(item["ItemCode"]);
                        mitem.Description = Convert.ToString(item["Description"]);
                        mitem.SubCategoryID = Convert.ToString(item["SubCategoryID"]);
                        //       mitem.RequiredHOD = Convert.ToBoolean(item["RequiredHOD"]);
                        if (item["RequiredHOD"]== "1")
                        {
                            mitem.RequiredHOD = (Convert.ToString(item["RequiredHOD"]) == "Yes");
                            //mitem.RequiredHOD = "Yes";
                        }
                        else
                        {
                            mitem.RequiredHOD = Convert.ToString(item["RequiredHOD"]) == "No";
                            // mitem.RequiredHOD = "No";
                        }


                        lists.Add(mitem);
                    }
                    return lists;
                }



                return ritem.GetAllItemBySubCategoryID(sid).GetDataTable();



            }
        }
