How can we pass a c# list/ (paged List) as report source to trdp file,calling a controller method returning the current view in asp.net core?

We have a project that uses Crystal Reports for Visual Studio. And we are considering migrating to the Telerik Report.
I downloaded the trial version 13.1.19.618
And I created the same report we have in crystal.

The report is large, around 18,000 records.
But it's just data, 14 columns, no calculations, no totalizers, no graphs.

On my development machine, this report on crystal runs in less than 2min (exports to PDF) and there is not too much memory or processing.

Already when I will run the version of telerik. I left running more than 40min and did not finish. Memory consumption was around 2GB and processing around 30% all the time.
I also tried to run the preview in Visual Studio, same problem.

So I reduced it to 400 records.
Crystal around 2 seconds to generate and display in browser.
The telerik took about 5 minutes, with the same memory problems.

The query runs in less than 3 seconds (18,000 records).

I can't understand what the problem is.
I've used the wizard, started the blank report. And always the same problem.

I was disappointed with the performance.

Hi,

We have installed the latest version of Telerik reports version 11.2.17.913. After installation we removed all the old references and referenced the 11.2.17.913 version of DLLs. Added the latest JS file into our application.Now the problem is we are getting - "Error registering the viewer with the service.An error has occurred.Object reference not set to an instance of an object." on the report viewer. We are using MVC 5 and Visual Studio 2017. Can you please provide a solution ASAP?

Thanks,

hi sir,

Below are the issues raised by warehouse on dynamic report:

Point Issue Expected result

A ------ Column D and column E is merge , This shouldn’t merge as they need to use for reporting purpose(the example show in below screenshoot)

http://prntscr.com/o1rmmc

B ------ When exported, it is converted to text. Please export it out to excel as numbers(like date as date integer as number)(the example show in below screenshoot)

http://prntscr.com/o1rjiv

C ------ Column A with blank value generated Please remove the column. This is not needed(the example show in below screenshoot)

This three issue rectify soon

 

I want to build a base Report form "BaseReport" (Inherits Report), so that I put "Company Name", "No. of pages", etc. inside. Then all reports are inherited "BaseReport" so as to make report layout consistent. But I failed.

Any hints?

Benson.

Hi,

I am trying to generate reports with a group which contains a text box(title of the table) and a table. The 'GroupKeepTogether' property of the group is set to true and its contents' (text box and table) 'KeepTogether' property to false. When I try to generate the report, the second table is getting generated in the third page even though there's space in 2nd page(which has only two rows of the first table). Is there a way to force the report to utilize the free space of the all pages.

Please refer the screenshot

Hi,

It would be great if you could introduce the ability to create custom reusable color palettes
in Telerik Report Designer (standalone),
so I don't have to declare the same set of colors for each chart I need them.

Cheers

Can we set report data  source dynamically in .trdp file, without using the wizard?

I found that when I click the export button of the report. It triggers query the database again. It seems the export button re run the report again. What cause the export button to run the query again? How can I fix it?

I am trying to connect to a web api via the webservice data connector in the standalone report designer. I have been able to return the data in json format via Postman with the same query parameters, but when i try to configure the data source in the report designer, I get the following error. 

System.InvalidCastException: Unable to cast object of type 'System.String' to type 'Newtonsoft.Json.Linq.JToken'.

Any thoughts on what the issue could be?
