Hi All,

I wanted to pass the viewmodel to report viewer in Reportview.cshiml. but I havn't got any such examples . always seeing the example on to bind the datasource in the ReportController . binding data source from report controller working as expected but looking for help on the view model binding in Razor Syntax.

 

My Cshtml Code

 

@using ReportingLibrary
@using Telerik.ReportViewer.Mvc
@using CPGUX.ProjectManagement.Core.Entities
@using CPGUX.Utility.Helpers
@model IEnumerable<ProjectDetails>

 

@(Html.TelerikReporting().ReportViewer()
 .Id("reportViewer1")
 .ServiceUrl(Url.Content("~/api/reports/"))
 .TemplateUrl(Url.Content("~/ReportViewer/templates/telerikReportViewerTemplate-FA.html"))
 .ReportSource(new Telerik.Reporting.TypeReportSource() { TypeName = typeof(CPGUX.ReportingLibrary.AllProjectsByUser).AssemblyQualifiedName })
 .ViewMode(ViewMode.Interactive)
 .ScaleMode(ScaleMode.Specific)
 .Scale(1.0)
 .PersistSession(false)
 .PrintMode(PrintMode.AutoSelect)
 .Deferred()
)

 

 

ReportController.cs

 

public Telerik.Reporting.ReportSource Resolve(string report)
{
Report reportInstance = null;
if (report.Contains("AllProjectsByUser"))
    {

       string result = _projectController.GetProjectNumberSession();// new ProjectController().GetProjectNumberSession();
      reportInstance = new AllProjectsByUser();
      reportInstance.DataSource =  _projectService.FindProjectsByUser(IIdentityUser, 100, 0); // don't want to call instead of binding should haven in viewer itself

    }

}

Hi Keerthi,

The MVC wrapper of the HTML5 Viewer renders the Javascript object and scripts required for creating the viewer. The page still uses the HTML5 Viewer that relies on the Reporting REST service - client-server technology, not MVC.

Thus data cannot be set through the controller that updates the view. Data can be set on the server where the Reporting REST service is running, and reports are processed and rendered.


My recommendation is to let users edit data and then save it on the server. This allows you to use a data source component to get data from the server (the source). If you need to filter data on retirval, you can use a parameterized data-retrieval method as in Connecting Telerik Reporting to OData feeds.

Regards,
Stef
