前台取数据：

$.post("Default.aspx", { flag: "ViewPage" }, function (dataStr) {
                var dataObj = eval("(" + dataStr + ")");
                if (dataObj.error != "") {
                    $("#myGrid").hide();
                    $("#errorTip").show();
                    $("#errorTip").html(dataObj.error);
                } else {
                    if (dataObj.data.length > 0) {
                        for (var i = 0; i < dataObj.data.length; i++) {
                            var d = (data[i] = {});
                            d["PageID"] = dataObj.data[i]["PageID"];
                            d["PageName"] = dataObj.data[i]["PageName"];
                            d["PageSeq"] = dataObj.data[i]["PageSeq"];
                            d["DisplayInterval"] = dataObj.data[i]["DisplayInterval"];
                            d["Display"] = dataObj.data[i]["Display"];
                        }
                        grid = new Slick.Grid("#myGrid", data, columns, options);
                    }
                }
            });
