Hi,
I'm trying out Telerik Reporting for .NET Core and I'm having an issue configuring the export device settings for CSV I've added the app.config file specified at the bottom of: http://docs.telerik.com/reporting/html5-report-viewer-asp-net-core
This app.config is being picked up by the program because it allowed me to input the connection string and run up the report.
After this I tried adding in extension settings as detailed in your support blog: http://www.telerik.com/support/kb/reporting/details/configuring-the-csv-rendering-extension
My implementation is below:
<configuration> <configSections> <section name="Telerik.Reporting" type="Telerik.Reporting.Configuration.ReportingConfigurationSection, Telerik.Reporting, Version=10.2.16.914, Culture=neutral, PublicKeyToken=a9d7983dfcc261be" allowLocation="true" allowDefinition="Everywhere"/> </configSections> <Telerik.Reporting> <Extensions> <Render> <Extension name="CSV"> <Parameters> <Parameter name="NoHeader" value="true"/> <Parameter name="NoStaticText" value="true"/> </Parameters> </Extension> </Render> </Extensions> </Telerik.Reporting> <connectionStrings> <add name="XXX" connectionString="XXX security=True;MultipleActiveResultSets=True;App=EntityFramework;Asynchronous Processing=true" providerName="System.Data.SqlClient" /> </connectionStrings></configuration>
I'm wondering if:
Thanks,
Josh
Hello,
We've got a problem with the PageCount property over here. Most of the time it works (always but once...), So it seems like the pagecount has a bug?
Is there a known bug at the moment?
Our scenario is:
We've got 6 pages, but the PageCount was 5. Pagenumbering works like fine.
It happens only when there is a certain amount of data on the pages, so when I had less data, the PageCount was 6, so correct.
Any ideas?

Dear Telerik,
we are trying to use a report file Item.trdx with ObjectDataSource in .NET MVC but the view can not render my report.
1) In ReportDesigner
I created a file Item.trdx, then tried to link to a fake sqlDataSource to test in preview mode all good.
2) ObjectDataSource: I have below classes in Model (I may build these classes into class library .dll later if required)
public class
ItemLocationModel
{
public string ITEM_NO { get; set; }
public string PREV_LOC { get; set;}
}
public class ItemLocation
{
[DataObjectMethod(DataObjectMethodType.Select)]
public static IList<ItemLocationModel> GetItemLocation(string item_no)
{
List<ItemLocationModel> l =new List<ItemLocationModel>();
//fill up data here based on item_no....
return l;
}
}
3) In Controller: I am trying to use Resolver
class
CustomReportResolver : Telerik.Reporting.Services.Engine.IReportResolver
{
public Telerik.Reporting.ReportSource Resolve(string item_no)
{
Telerik.Reporting.ObjectDataSource objectDataSource = new Telerik.Reporting.ObjectDataSource();
objectDataSource.DataSource = ItemLocation.GetItemLocation(item_no);
Telerik.Reporting.Report report = new Telerik.Reporting.Report();
report.DataSource = objectDataSource;
Telerik.Reporting.InstanceReportSource reportSource = new Telerik.Reporting.InstanceReportSource();
reportSource.ReportDocument = report;
return reportSource;
}
public class ReportsController : Telerik.Reporting.Services.WebApi.ReportsControllerBase
{
protected override Telerik.Reporting.Services.Engine.IReportResolver CreateReportResolver()
{
return new CustomReportResolver();
}
protected override Telerik.Reporting.Cache.Interfaces.ICache CreateCache()
{
return Telerik.Reporting.Services.Engine.CacheFactory.CreateFileCache();
}
}
4) In CSHTML: i am populating the ReportViewer
<div id="reportViewer1" class="k-widget">
loading...
</div>
<script type="text/javascript">
$("#reportViewer1")
.telerik_ReportViewer({
serviceUrl: "/api/reports/",
templateUrl: '/ReportViewer/templates/telerikReportViewerTemplate-9.0.15.324.html',
reportSource: {
report: 1
}
});
</script>
5) RESULT:
I debugged the Resolve() function and it clearly got data correctly, but it does not show my my report, it totally empty without any error even the template was loaded. My questions are:
- How to load data returned back from an InstantDataSource in CSHTML file?
- How to bind my returned data with a report file .trdx?
Thanks so much in advanced.

Is there a way to convert a column from your data source to an array/concatenated string?
To give a little more detail:
I'm getting back a list of data from my query looking something like this
I then need to pass the comma delimited list of column 3 ("1, 23, 78") into a sub-report to be displayed.
Any help would be appreciated.


Following these guide:
https://www.telerik.com/blogs/telerik-reporting-and-aspnet-core
https://docs.telerik.com/reporting/html5-report-viewer-asp-net-core-2
to create a REST service for Telerik Report, but whatever I do, I have always get this error:
Am I missing something?

I've followed the instructions in the documentation for setting up a the MVC Report Viewer in my ASP.NET MVC web application. The app path maps to "~/Reports", and in the root of my project I have a folder named 'Reports' which contains the SampleReport.trdp. I believe I have all the other configuration in place (Global.asax, web.config etc.).
How do I view this sample report? What is the URL for viewing any reports? The documentation is very minimal, are there any tutorials for setting up Telerik reporting in an MVC app?
Hi,
I use the asp.net webforms viewer and set the report by setting
reportViewer1.ReportSource.Identifier = reportFile;
I have a controller which uses a custom resolver
public class ReportsController : ReportsControllerBase
Apparently this page uses the REST service to load the report but how does it know what url to use for the service? I haven't configured this explicitly as far as I can see so it seems to be hardcoded/defaulted?
