Hello,

Maybe this is dumb, but I'm having a surprisingly difficult time trying to hide a report header programmatically.

I can set the visible property using a binding or something, but the height of the item remains in the rendered report. I've had a lot of trouble binding the height property, but I think I figured out a way to do it and it doesn't seem to have any effect.

How can I have a report parameter that's something like "ShowHeader" and have that determine whether the header of the report renders?

Thanks,

Mike

And i got question its impossible to run your report on Redhat os?

Thank you sir.

Telerik Report rendering is very slow in VS2017 Enterprise (in both RC3 and RC2)  -however it works fine in VS2015.

Is this a known issue ?

Hi, 

We're currently trying to setup a build server using visual studio online, and one of the projects in our solution uses the wpf Report viewer.  We're getting the following errors while that particular project builds.  Would you be able to help?

MSLCRM2\MSLCRM2\Themes\Office2013\Telerik.ReportViewer.Wpf.xaml (13, 6)

Note: I found this thread and tried to follow the advice in there, but it hasn't worked http://www.telerik.com/forums/build-failure

We are currently migrating from the older ReportViewer to the newer HTML5 ReportViewer.  We use a ReportBook to display all our reports, regardless if it is one or multiple reports.  Inside the ReportBook’s constructor, a method is called that determines which reports are to be displayed and puts them in a loop that does the following:
1. Uses LINQ to SQL to generate the data to be displayed,
2. Instantiates the report,
3. Assigns the generated data to the report’s DataSource property, and
4. Adds the report to a ReportBook.

All of this is done in code, in the ReportBook’s constructor.  Yes, I realize Telerik probably wouldn’t recommend doing it this way.  The individual reports do not use the designer to create a SqlDataSource, ObjectDataSource, etc…

This design worked with the old ReportViewer because it simply instantiated the ReportBook once on the server and returned markup back to the client.

The HTML5 ReportViewer seems to expect that the report use data sources which are generated as a result of the report being created instead of having the data generated before the report is created.  Our problem is that the HTML5 ReportViewer calls the ReportBook’s constructor 3 times, which results in the data for each report to be generated 3 times.

I have tried using counters to generate the data only 1 of the 3 times the ReportBook’s constructor is called, but the data does not display.  I’ve tried on the first call, the second call, and the third call, but the report does not display the data. 

Therefore, I can’t think of a way to upgrade to the HTML5 ReportViewer without making drastic changes to our reports.

Given our current design, can anyone from Telerik suggest a way to upgrade with minimal changes?

Is there anyway to cancel a report being generated with RenderReport?  For example, we are creating a PDF of a report that takes some time to finish.  Is there any asynchronous ways of creating the report such that we can cancel its execution? 

 

I saw a post on here a few years ago that it couldn't be canceled, but I'm hoping something has been done since then to change this.  Thanks for any guidance.

Example:

ReportProcessor reportProcessor = new ReportProcessor();                      

ReportLibrary.TestReport report = new ReportLibrary.TestReport();                                               InstanceReportSource reportSource = new InstanceReportSource();                         

reportSource.ReportDocument = report;                         

RenderingResult result = reportProcessor.RenderReport("PDF", reportSource, null);

I have a class library where all my reports are. One of my reports needs to be displayed and exported to PDF in landscape mode instead of portrait. In my web application which is a MVC Core application using a target framework of 4.6.1 displays the report fine in the report viewer. 

Do I need to do something with the jQuery to tell the report to print according to the class report settings?

Do I need to set something else in the report definition itself that will take care of it?

See the screenshot for the report properties settings.

Here is the jQuery I am using to render the report viewer:

I don't seem to be able to find a chart control for a Funnel. I suspect there is not one at this time.

Has anyone created a work around for this yet using a bar chart?

Hi,

I have two projects; a website and a web api. (.net Core 2.0 )

The website has the following html;

 $("#reportViewer1")
                .telerik_ReportViewer({
                    //serviceUrl: "/api/reports/",
                    serviceUrl: "@ViewBag.TelerikReportServerUrl",
                    reportSource: {
                        report: "TelerikReportService.Report, TelerikReportService", 
                        //report: "Barcodes Report.trdp",
                        parameters: {}
                    },
                    viewMode: telerikReportViewer.ViewModes.INTERACTIVE,
                    scaleMode: telerikReportViewer.ScaleModes.SPECIFIC,
                    scale: 1.0,
                });

And within the web API project I have been trying to create an example Report Class file that can be served up to the client.
This is how far I have got, but it wont work and I cannot find an example of this anywhere in the forums.

("Barcodes Report.trdp" works fine, just a CODED report class,  I cannot get to work)

I get the error;

"Unable to get report parameters.
An error has occurred.
