Grid++Report Web入门ASPX与MVC使用

引用附件的三个js文件

网站根目录下建立文件夹，将报表插件放在里面

由于报表文件是grf的所以需要web.config中添加下面的mime

 <system.webServer>
    <staticContent>
      <mimeMap fileExtension=".grf" mimeType="报表模板文件" />
    </staticContent>
  </system.webServer>

页面

测试结果

MVC使用：结果和上面一样

页面基本和上面一样

function ReportPrintPreview() {
            //Report.PrintPreview(true);//打印预览
            Report.Print(true);//直接打印
        }
   function btnPreview_onclick() {
            if (!Installed) {
                alert("请先安装插件!");
                return false;
            }
            Report.LoadFromURL("report/Barcode.grf");
            //请求地址
            AjaxReportRun(Report, "HelloWorld/Report", ReportPrintPreview);
        }

//控制器下的方法
  public ActionResult Report()
        {
            return Content(CreateBarcodeData());
        }
