在MVC4当中的ajax方法当中不执行Document_LocateDataSource方法

登录

1.页面按钮点击之后调用JS方法

2.在JS方法当中调用后台的Ajax方法

3.在后台的Ajax方法当中给报表参数赋值：

4.结果不走下面的方法

本地直接运行的示例
C:\Users\lenkaguo\Documents\GrapeCity Samples\ActiveReports 11\Professional\ActiveReportsWithMVC5WebAPI\C#

在cshtml页面中编写HTML5Viewer，直接仿照下面这段代码，有三个要点:
1.在head标签中添加js引用
2. 添加css引用
3. 在body里面声明<div id='viewerContainer'>用来加载报表。

@{
ViewBag.Title = "Home Page";
}
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>ActiveReports HTML5 viewer - basic sample</title>
<link href="css/theme-cosmo.css" rel="stylesheet">
<link href="css/site.css" rel="stylesheet">
<link href="css/GrapeCity.ActiveReports.Viewer.Html.css" rel="stylesheet">
</head>
@section scripts{
<script src="~/Scripts/jquery-1.10.2.js"></script>
<script src="~/Scripts/bootstrap-3.0.0.js"></script>
<script src="~/Scripts/knockout-2.3.0.js"></script>
<script src="~/Scripts/GrapeCity.ActiveReports.Viewer.Html.js"></script>
<script type="text/javascript">
$(function () {
var viewer = GrapeCity.ActiveReports.Viewer({
element: '#viewerContainer',
reportService: {
url: '/ActiveReports.ReportService.asmx'
},
report: {
id: "PageReport.rdlx"
},
uiType: 'desktop',
$(viewer.toolbar).hide();
});
</script>
}
<body>
<div id="viewerContainer">
</body>

假如后台调用的是Controller方法

怎么给报表绑定数据源

Lenka.Guo · Lenka.Guo

可以，参考本地示例:C:\Users\lenkaguo\Documents\GrapeCity Samples\ActiveReports 11\Professional\ActiveReportsWithMVC\C#
示例中给出的Controller 运行时绑定数据源

using System.Web.Mvc;
using GrapeCity.ActiveReports.Samples.ActiveReportsWithMVC.Models;
using GrapeCity.ActiveReports.Samples.ActiveReportsWithMVC.Reports;
using System.IO;
namespace GrapeCity.ActiveReports.Samples.ActiveReportsWithMVC.Controllers
{
public class HomeController : Controller
{
private object _reportdata = null;
/// <summary>
/// Returns view Index.cshtml
/// Passes the Entire Customers list to its model
/// </summary>
/// <returns>Index.cshtml</returns>
public ActionResult Index()
{
return View("Index", Repository.GetCustomers());
}
/// <summary>
/// Start method
/// </summary>
/// <returns></returns>
public ActionResult Start()
{
return Index();
}
/// <summary>
/// Returns View Details.cshtml
/// </summary>
/// <param name="id">Customer ID</param>
/// <returns>Details.cshtml</returns>
public ActionResult Details(string id)
{
return View("Details",Repository.GetCustomer(id) );
}
/// <summary>
/// Returns View Viewer.cshtml
/// </summary>
/// <param name="id">Customer id</param>
/// <param name="reporttype">Section/Page</param>
/// <returns>Viewer.cshtml</returns>
public ActionResult ViewReport(string id,string reporttype)
{
return View("Viewer", new ReportDescriptor { Id = id, Type = reporttype });
}
/// <summary>
/// Generates Separate Views for Section and Page Reports
/// </summary>
/// <param name="reportdesc"></param>
/// <returns>WebViewer.ascx</returns>
public ActionResult GetReport(ReportDescriptor reportdesc)
{
object report = null;
switch (reportdesc.Type)
{
case "Section":
report = new OrderReport {DataSource= Repository.GetOrders(reportdesc.Id) };
break;
case "Page":
_reportdata = Repository.GetDetails(reportdesc.Id);
report = new PageReport(new FileInfo(Server.MapPath("~/Reports/OrderDetailsReport.rdlx")));
((PageReport)(report)).Document.LocateDataSource += Document_LocateDataSource;
break;
}
ViewData["Report"] = report;
return PartialView("WebViewer");
}
void Document_LocateDataSource(object sender, LocateDataSourceEventArgs args)
{
args.Data = _reportdata;
}
}
}
