合并和分组库代码问题

Question

我正在编写C＃代码来合并网站集中的多个库并对其应用分组。但是，分组不包括来自其他站点的文档，无论是否共享相同的元数据。下面，蓝盒文档来自一个站点，绿盒文档来自其他站点，它们不会组合在一起。

这是我的代码，

             DataTable dt = new DataTable();
             DataRow dr;
             DataColumn dc;

             SPSite curSite = SPContext.Current.Site;
             SPWebCollection subSites = curSite.AllWebs;

             dc = new DataColumn("Title", Type.GetType("System.String"));
             dt.Columns.Add(dc);
             dc = new DataColumn("ReferenceNo", Type.GetType("System.String"));
             dt.Columns.Add(dc);
             dc = new DataColumn("Domain", Type.GetType("System.String"));
             dt.Columns.Add(dc);
             dc = new DataColumn("Created", Type.GetType("System.DateTime"));
             dt.Columns.Add(dc);

             for (int i = 0; i < subSites.Count; i++)
             {                 
                 SPListCollection lists = subSites[i].Lists;

                 foreach (SPList list in lists)
                 {
                     if (list.Title == "Published Documents")
                     {
                         SPQuery myquery = new SPQuery();
                         //myquery.Query = "<GroupBy><FieldRef Name='Domain' /></GroupBy><OrderBy><FieldRef Name='Created' Ascending='False' /></OrderBy>";
                         myquery.Query = "<GroupBy><FieldRef Name='Domain' /></GroupBy>";

                         SPListItemCollection items = list.GetItems(myquery);

                         foreach (SPListItem item in items)
                         {
                             if (item != null)
                             {
                                 dr = dt.NewRow();

                                 dr["Title"] = item["Title"];
                                 dr["ReferenceNo"] = item["ReferenceNo"];
                                 dr["Domain"] = item["Domain"];
                                 dr["Created"] = item["Created"];

                                 dt.Rows.Add(dr);
                             }
                         }

                     }

                 }
             }

             //dt.DefaultView.Sort = "Created DESC";

             spGridView.AllowGrouping = true;
             spGridView.AllowGroupCollapse = true;
             spGridView.GroupField = "Domain";

             spGridView.DataSource = dt;
             spGridView.DataBind();

更新:: ，使用域排序数据表修复了问题..

**dt.DefaultView.Sort = "Domain";**

使用Domain对数据表进行排序修复了问题..

dt.DefaultView.Sort = "Domain";

完美对我有用。一切顺利，我们需要   dt.DefaultView.Sort = "Your Sorting Attribute";
