Hello there ,
I have a problem to loading the report from localhost , below is the my project environment
1. Angular 5 , typescript 2.5.3 , ASP.Net Core2.0 , VS 2017 and Telerik Selhost Report service project .
Issue : I have publish the project one my folder then i create a web site from my IIS then reference to my published folder . Then i have tested from browser like " http://localhost:12345/api/reports " then formats are loading
[{"name":"PDF","localizedName":"Acrobat (PDF) file"},{"name":"CSV","localizedName":"CSV (comma delimited)"},{"name":"XLS","localizedName":"Excel 97-2003"},{"name":"XLSX","localizedName":"Excel Worksheet"},{"name":"PPTX","localizedName":"PowerPoint Presentation"},{"name":"RTF","localizedName":"Rich Text Format"},{"name":"IMAGE","localizedName":"TIFF file"},{"name":"MHTML","localizedName":"Web Archive"},{"name":"DOCX","localizedName":"Word Document"},{"name":"XPS","localizedName":"XPS Document"}]
Then i try to call this report from Angular project using type script like below .
@Component({
selector: 'printReport',
template: `<tr-viewer #viewer1
[containerStyle]="viewerContainerStyle"
[serviceUrl]="'http://localhost:12345/api/reports'"
[templateUrl]="'node_modules/@progress/telerik-angular-report-viewer/dist/dependencies/telerikReportViewerTemplate-sass.html'"
[reportSource]="Viewdata"
[scaleMode]="'SPECIFIC'"
[scale] = "1.0"
[renderingEnd]="boundReportRendered"
[error]="ReportError"
[viewMode]="'PRINT_PREVIEW'">
</tr-viewer>
<button id='btnprint' style="display:none;" name='btnprint' (click)="viewer1.commands.print.exec()">Print</button>`,
})
So, report is not loading then i check this in Fiddler it gives error like :
stackTrace= at Telerik.Reporting.Services.Engine.ReportEngine.ResolveReportSource(String report)
at Telerik.Reporting.Services.Engine.ReportEngine.GetParameters(String clientID, String report, Dictionary`2 parameterValues)

I am unable to get either of the new .NET Core samples to compile with both giving me the following error:
SeverityCodeDescriptionProjectFileLineSuppression State
ErrorNU1101Unable to find package Telerik.Reporting.OpenXmlRendering. No packages exist with this id in source(s): https://dotnetfeed.blob.core.windows.net/dotnet-core/index.json, Microsoft Visual Studio Offline Packages, nuget.org, TelerikCSharp.AspNetCoreDemoC:\Program Files (x86)\Progress\Telerik Reporting R1 2019\Examples\CSharp\Asp.NetCoreDemo\CSharp.AspNetCoreDemo.csproj1
Any thoughts?
Thank you,

I have previously created a report in the standalone designer and successfully deployed it to my server with an api. I was able to view it in my Angular application. This worked fine using the .trdp file. However, I recently tried creating a report in the Visual Studio designer and am having difficulty getting it deployed to my server. I see there is no .trdp file. Are there any files that are supposed to be generated and reside in the reports folder if I am doing it this way? Is everything just compiled?
I am getting the error "Unable to get report parameters. Report 'MyReport' cannot be resolved." My report does not have any parameters and my controller code contains a call to .AddFallbackResolver.
Please let me know what steps can be taken to a resolution.
Thanks,
Jennifer

We have a report where the data sources are provided as CSV files. In some scenarios, not all of these CSV files provided even though they are configured in the report. In standalone designer fields that have missing data sources will only show empty spaces. But when trying to generate through programmatically an error given as "Output error: Could not find file 'C:\DataSource\MissingFileName.csv'.". Is there a way that programmatically to remove those data sources from a report item if the CSV file is missing which will show empty spaces in the output file?
Thank you
Hello. I've faced a problem trying to use HTML5 MVC Report viewer when using a .dll file loaded during runtime. I'm using a custom report resolver which creates TypeReportSource, sets a type name which I get from the loaded .dll and then returns the created report source. However, the report viewer displays an error. (Stack trace below).
Is it possible to use reporting service with a dynamically loaded .dll like that? Or is it only possible if I reference the .dll in my project directly (when I do that, everything works, but this is obviously not a desired way for me)

We need to know if there is any workaround for printing each Table Group on New page. Basically our Report Datasource is already bind and having Group with setting Page Break After in Group Footer. Report contains a Table having different Datasource also having Grouping. Now it is required that each Table Group should appear on next Page addition to existing Report group.
Please advise any way to address the requirement...
Thanks,

I have a subreport that is being hidden under certain conditions. That is no problem and is working. However it still appears the subreport is executed when it's visibility is set to false, can I stop that behaviour.
The reason is if the subreport contains too much information I don't want it to run as it takes too long.
