Hi, I want to create a MVC Application which uses an external API where I will get my data from. Its my first time using telerik reporting and I think I'm supposed to use the objectDataSource component based on the documentation, because I don't need to use the sqlDatasource. Does anyone have any repos or demo app that I can follow? I would really appreciate it. Thanks.

I am trying to pass a model to the report using typeReportResource to set it as its dataSource, am I doing this wrong?

This is my Controller 

    public class ReportViewerController : Controller
    {
        private IOrganisationLogic _organisationLogic;
        public ReportViewerController(IOrganisationLogic organisationLogic)
        {
            _organisationLogic = organisationLogic;
        }
        public ActionResult Index()
        {
            var organisation = _organisationLogic.GetOrganisation();            

            var typeReportSource = new TypeReportSource();
            typeReportSource.TypeName = typeof(OrganisationSample).AssemblyQualifiedName;

            typeReportSource.Parameters.Add(new Parameter("flag", true));
            typeReportSource.Parameters.Add(new Parameter("organisation", organisation));

            return View(typeReportSource);
        }
    }

 

And here is the report design that i've created...


    public partial class OrganisationSample : Telerik.Reporting.Report
    {
        private IOrganisationLogic _organisationLogic;
        public OrganisationSample(bool flag, OrganisationLogic organisation)
        {
            //
            // Required for telerik Reporting designer support
            //
            InitializeComponent();

            //
            // TODO: Add any constructor code after InitializeComponent call
            //

            if (flag)
            {
                this.DataSource = organisation;
            }
        }
    }


what is the best approach I could do? Iwant to set the objectDataSource dynamically, each report has its own objectDataSource and I just want a single viewer that can use render multiple reports.

Hi,

I have a hard time trying to configure a Graph with line series in the stand alone Report Designer.
I need a simple chart with one or more line series. The line series are Numerical on both axes (it's a temperature (X) vs value (Y) plot).

The data for the Graph will be provided at runtime.

My data source format is thus:

```
class Data

{
   List<double> Temperature {g;s;}
   List<double> Value {g;s}
}

```

I was able to 'import' the dll to the designer and the data source was set up correctly (I know this because I'm able to use other data sources to successfully populate other elements of the report).

----------------------------------

What I did so far?

* I inserted a new line graph into the report
* I tried setting the Category to Temperature and Value to Value in the Wizard
* I named the graph to be able to find it at runtime and set it's DataSource
* In various attempts to configure the graph I tried setting the X and Y axes of the Graph to Numerical type or X to Category and Y to Numerical (I get the legend and axes preview in the designer)
* At runtime I set the DataSource of the Graph the same way as DataSource of a Table (which works ok for the table): `((Graph)(report.Items.Find("nameOfGraph", true)[0])).DataSource = dataSourceObject;`

 

The problem I have is that there are no series in the generated report in the Graph while other parts of the report are populated correctly.

 

Could you please provide me with a walktrough of how to configure a line Graph in Report Designer with the assumption that the data will be provided at runtime?

 

Thanks!

I have an MVC ASP.Net 4.61 application. I have a report defined with a parameter and a filter. When I view the preview in the designer, the default parameter works fine and the report is filtered, but when I run the application and it is using RenderReport it appears that the filter is passing a null value to the query so no data is returned. If I put the parameter in a text box I see the Id. My id's are GUIDs stored in a varchar field. If I take off filtering it shows multiple records properly.

 

var PDFSource = new TypeReportSource();
 PDFSource.TypeName = typeof(rptEmail).AssemblyQualifiedName;
 PDFSource.Parameters.Add(new Telerik.Reporting.Parameter("Id", id));
 
 var ReportProcessor = new ReportProcessor();
 var result = ReportProcessor.RenderReport("PDF", PDFSource, null);
 string PDFPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "App_Data", "Test.pdf");

 

File.WriteAllBytes(PDFPath, result.DocumentBytes);

A customer requested that the parameters be closer together, instead of being distributed evenly across the entire width of the Report Viewer. Is there a simple way to do this?

Could you please tell me what property is different between the upper left graph and the lower graph.  I want the labels to display the same as the lower one but I a can not seem to locate what field is different.

Is it possible to set ObjectDataSource value at runtime?

 

We're trying to generate PDF's based on reports with data supplied at runtime. The structure of the object will always be the same but the values need to vary as this is supplied to the API.

 

For example:

public IActionResult GetReport(ReportData data)
        {
            var reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
            var reportSource = new Telerik.Reporting.UriReportSource();
            var deviceInfo = new System.Collections.Hashtable();
 
            reportSource.Uri = Path.Combine("Reports", "Report.trdp");
             
            // Need to set the value for the objectdatasource here somehow?
 
            Telerik.Reporting.Processing.RenderingResult result = reportProcessor.RenderReport("PDF", reportSource, deviceInfo);
 
            return new FileContentResult(result.DocumentBytes, "application/pdf")
            {
                FileDownloadName = "QuestionnaireReport.pdf"
            };
        }

I have a report, that shows lots of information on table. The table has many rows, that it takes extra paper. In this case I don't want to show additional rows after row #5(or row #10). 

Question is how to hide those extra rows in Telerik Report Designer?
