I am trying to upgrade an ASP.Net MVC (.net framework 4.6.1) application from Telerik Reporting R1 2020 to R1 2022 and can't even get the viewer to display.  The error on screen says

Cannot access the Reporting REST service. (serviceUrl = '/api/reportsapi/'). Make sure the service address is correct and enable CORS if needed. (https://enable-cors.org)

When I open the browser developer tools I see the error has occurred on the call to api/reportsapi/version and the exception message is:

Multiple actions were found that match the request: \r\nFormats on type FWT.MVC.ReportsAPIController

Any idea where to even begin looking?  The prior version worked flawlessly.  We do have a custom report resolver because we change the connection string based on the tenant ID of the logged in user, but I have upgraded that.

Hi all,

Some times we are getting above attached errors when generating reports. after pressing refresh button the report will load correctly. we are using .net 6 app to show the report viewer.

Hi guys,

is it possible to automatically refresh the Report Preview, after a user changed the parameter?
In one of my reports I have an Parameter. The value of it is part of the report.
Currently if I change the value, I have to click the filter symbol (hide/show parameters) to refresh the report and show the value.

Is it possible to refresh the report on value change?
Or at least if the click return?

Greetings Benedikt

I am using ABP 4.4.2 version along with .Net 5. This is an API that is being consumed by a javascript based frontend. Now I need to incorporate Telerik Reporting in my application. I am trying to follow the steps mentioned in the following url - https://docs.telerik.com/reporting/designing-reports/report-designer-tools/web-report-designer/how-to-set-up-in-.net-5-and-.net-core-3.1-applications

Now this documentation suggests to use a base controller class called ReportDesignerControllerBase.

And on the other hand, it seems ABP requires AbpController base class to be used in every controller.

This is where I am getting little confused on how to incorporate Telerik Reporting in the ABP application.

I also tried using ITransientDependency interface as mentioned in some of the older posts.

But nothing seem to work.

I would really appreciate if anyone can guide me on this.

We want to show company logo in the picturebox element. Company logo file path can be programmatically changed. For this purpose, we created CompanyLogo parameter in the report and the picturebox has binding with this parameter's value to set file path to the picturebox's value. Sometimes, company can be without logo. If company doesn't have logo, we want the picturebox to show nothing.

Problem here is if we bind the picturebox with the report parameter, it shows an error if the file path doesn't exist or empty:

If the parameter's value is empty then the picturebox show empty space, instead of the error. As an example, if you remove binding and keep picturebox's value blank then it will show empty space.

Any solution or workaround for this problem?

Hi all,

I have a following default code in a html file for a web designer.

$(document).ready(function () {
            $("#webReportDesigner").telerik_WebReportDesigner({
                persistSession: false,
                toolboxArea: {
                    layout: "list"
                },
                serviceUrl: "some url",
                report: "some_report_name",
            }).data("telerik_WebDesigner");
        });

I have also a custom report storage implemented from IDefinitionStorage, where I have a GetDefinition("some_report_name") method implemented in a custom way. In order to do that, I need to send additional parameters from a web designer (html code provided previously) but don't know how to do that. 

For example, I need to open SalesInvoice.trdx file and I do a following: report: "SalesInvoice.trdx". If i need to send additional parameter, let's say some kind of token, there is no good place to send it. As a work around, i am doing report: "SalesInvoice.trdx&token=123". The problem with this, it is appearing in a title of a web designer and I don't want that. In an attachments, there is a screenshot where it looks good with a simple name and the one which has a token in it.

So, the question is, can I send other parameters as well from a client side of web designer to the server like parameters or so?

In a HTML5 ReportViewer we can send report file name and parameters as a reportSource like this:

                    serviceUrl: serviceUrl,
                    reportSource: {
                        report: reportUrl,
                        parameters: reportParams,

Can we do the same? Or how can I do that?

Thanks, 

Dear Sir
