ProjectStore = new Ext.data.GroupingStore({ proxy: new Ext.data.HttpProxy({ url: "DATA/ProjectInfo/ProjectInfo.aspx", method: "POST" }), reader: new Ext.data.JsonReader({ fields: projectfields, root: "data", totalProperty: "totalCount" }), sortInfo: { field: 'region', direction: "ASC" }, remoteSort: true //服务器端排序 });SortInfo为对某列排序的代码。注意如果gridpanel采用了分页,要加上 remoteSort: true
