DevExpress MVC Report Demos 解析

找到控制器：

namespace DevExpress.Web.Demos {

public partial class InteractionController : ReportDemoController {

public ActionResult EmployeePerformanceReview() {

var model = ReportDemoHelper.CreateModel("EmployeePerformanceReview", Session, Request);

return DemoView("EmployeePerformanceReview", "EmployeePerformanceReview", model);

}

?

public ActionResult EmployeePerformanceReviewPartial(string reportID) {

return PartialView("EmployeePerformanceReviewPartial", ReportDemoHelper.CreateModel(reportID, Session, Request));

}

}

}

?

这里比较重要，我们需要找出传值的model到底有些什么？

因此先进入ReportDemoHelper.CreateModel方法：

public static ReportsDemoModel CreateModel(string reportID, HttpSessionStateBase session, HttpRequestBase request) {

return new ReportsDemoModel {

ReportID = reportID,

Report = ReportStorageHelper.LoadReport(reportID, session),

CurrentViewer = request.Params[ViewerSelectorState.Key],

EmulatorModel = new MobileEmulatorModel(reportID, request)

};

}

?

好了，找到有Report对象的赋值了，它从哪里来？（ReportStorageHelper.LoadReport）

?

public static XtraReport LoadReport(string reportId, HttpSessionStateBase session) {

var reportLayout = GetReportLayout(reportId, session);

if(reportLayout != null) {

using(var stream = new MemoryStream(reportLayout)) {

return XtraReport.FromStream(stream, true);

}

}

return ReportDemoHelper.GetReport(reportId);

}

以上就解释了Report Style file的来源了，理论上来讲，因该可以使用web和form设计的文件了。

?

找到无参数Action的视图：

@if(Model.IsHTML5Viewer) {

@Html.DevExpress().WebDocumentViewer(settings => {

settings.Name = "webDocumentViewer";

}).Bind(Model.ReportID).GetHtml()

}

else if(Model.IsMobileViewer) {

@Html.Partial("MobileEmulator", Model.EmulatorModel)

}

调试，看它的Bind对象：

?

找回Bind对象Action：
public ActionResult EmployeePerformanceReviewPartial(string reportID) {

return PartialView("EmployeePerformanceReviewPartial", ReportDemoHelper.CreateModel(reportID, Session, Request));

}

?

找到PartialView：

@using DevExpress.Web.Demos.Code.Designer

@model ReportsDemoModel

@Html.DevExpress().DocumentViewer(settings => {

settings.Name = "DocumentViewer";

settings.Report = Model.Report;

settings.SettingsSplitter.DocumentMapCollapsed = true;

settings.CallbackRouteValues = new { Controller = "Interaction", Action = "EmployeePerformanceReviewPartial", ReportID = Model.ReportID };

settings.ExportRouteValues = new { Controller = "Interaction", Action = "DocumentViewerExportTo", ReportID = Model.ReportID };

}).GetHtml()

?

好了，到这里就是主要代码了。

但是怎么动态绑定数据还是没闹明白，跟CS还是有很大的区别啊。
