ext js gridpanel绑定到动态生成的store

在页面中引用一个gridpanel 并给它指定一个store

然后在后台代码中给store动态灌数据

            string file_id=e2.ExtraParams["file_id"].ToString();
            string FN_SUB_NAME = e2.ExtraParams["FN_SUB_NAME"].ToString();
            string FN_TEMPFILE_NAME = e2.ExtraParams["FN_TEMPFILE_NAME"].ToString();
            string FN_FILE_CODE = e2.ExtraParams["FN_FILE_CODE"].ToString();
            string FN_FILE_STATE = e2.ExtraParams["FN_FILE_STATE"].ToString();
            string FN_AUDIT_STATUS = e2.ExtraParams["FN_AUDIT_STATUS"].ToString();
            string FN_VERSION = e2.ExtraParams["FN_VERSION"].ToString();
            string FN_FILE_DIRECTORY = e2.ExtraParams["FN_FILE_DIRECTORY"].ToString();
            string FN_CREATE_USERID = e2.ExtraParams["FN_CREATE_USERID"].ToString();
            string FN_LC_COMPUTER_NAME = e2.ExtraParams["FN_LC_COMPUTER_NAME"].ToString();
            string FN_FILE_SIZE = e2.ExtraParams["FN_FILE_SIZE"].ToString();

            Store_file.DataSource = new object[] {
                new object[] {"名称",FN_SUB_NAME },
                new object[] {"文件名",FN_TEMPFILE_NAME },
                new object[] {"档案号",FN_FILE_CODE },
                new object[] {"文件状态",FN_FILE_STATE},
                new object[] {"校审状态",FN_AUDIT_STATUS },
                new object[] {"版本号",FN_VERSION},
                new object[] {"登出路径",FN_FILE_DIRECTORY},
                new object[] {"操作用户",FN_CREATE_USERID},
                new object[] {"操作计算机",FN_LC_COMPUTER_NAME },
                new object[] {"文件大小",FN_FILE_SIZE} };
            Store_file.DataBind();
在同时 gridpanel就有了新的数据
