Hello,

We have Float type parameter in our report. Default value of the parameter is zero. When we preview this report on Standalone Designer it works fine (see WhenRunningOnStandaloneReportDesigner.PNG), but when we preview this report on Html5 Report Viewer it shows error (see ErrorWhenRunningOnHtml5ReportViewer.PNG, Internal Server Error
Invalid value for parameter 'FloatParameter')

To reproduce this problem we used "CSharp.Net5.Html5IntegrationDemo" project and created sample report (this report is in attached archive file SampleReportToTestFloatTypeParameter.zip). So, we want that it should not show error when we run the report on html5 report viewer.

Is there any solution for this?

Hello,

I'm  using Telerik Reporting version 15.0.21.326 and WPF report viewer with REST services. When my custom report source resolver return null or custom exception I have exception "Object reference not set to an instance of an object" with stack trace:

Hi,

I'm trying to setup the telerik reporting on a asp net core project targeting net462 and I can't configure it unless I use the app.config, but using the app.config is not an option, nor changing to .net core, so, anyone knows a way to setup this properly?

Thank you

Hi there

I'm trying to print labels with a label printer using Telerik Reporting. I just updated it to the latest version to make sure that I don't have any version conflicts. In my application I created a report by designer with just one textbox to make sure it's not my data which causes the problem.

I then use this code on button click:

I set a breakpoint on line 20 on the PrintReport method. When I continue the code, it takes about three minutes to finally print the report and the code to continue. I'm wondering why this is taking so long. Is there anything wrong with my code during preparation, is there a setting missing or causing problems?

Cheers,
Roman

Hello,
I am working with Reporting using HTML5 Report Viewer. I have designed Custom Report Resolver for showing up the reports. My reports have WebServiceDatasource that use OData to load data from database. Sometimes OData can through an exception. For example, When OData request select a property which doesn't exist in requested table, then there is error in OData saying like: "Could not find a property named 'NewProperty' on type 'EntityType'".

Custom Report Resolver also through exception, because there is error in OData. But, custom report resolver showing error message with this text: "Response status code does not indicate success: 500 (Internal Server Error)".

I need real error message. Can someone know how to get internal error message as the OData error message?

It is announced that the new release Telerik R1 2020 includes a new report viewer control for Blazor applications. 

2 questions:

1) Is it possible to see a demo? I couldn't find one on the telerik site.

2) Will the Web report designer work in Blazor?

Hi there,

currently we're able to use Telerik Reporting to fulfill our project requirements (.NET MVC), which is to generate Realtime resume/CV (curriculum vitae) in a divided page. Left side of the page is the form to collect the resume data, right side of the page is the Report Viewer. Basically, the processes are :

1. As user, I fill the resume form
2. Using an event, after 1 second we collect that data and put it as Report parameter and then send it to our report using the same method as here https://docs.telerik.com/reporting/html5-report-viewer-howto-custom-parameters
3. Simultaneously, data collected is also updated into our database from backend process.

We did a test to create resume on our project (which already deployed into our Azure environment) simultaneously by some users. What happened is, every time the report refreshed, consume about more or less 300MB of RAM per user.

We did another test, which is to exclude process no. 3 to make sure our backend process is not the problem. The test result is the same.

Do you have any suggestion regarding our issue ? Thank you.
