I have a report that calls a subreport. The subreport is noting but a table. I would like to not show the subreport or the table in the subreport if the data row count of the subreport/table is 0.

I have found several threads thinking they what I want but none of them work.

attached is a sample of what I am trying to do 

The company I work for generates multiple PDF reports everyday on a schedule. We loop through a list that we generate reports for. The reports have multiple sub reports that have datasources that connect to our databases. The sub reports have sub reports as well. We have run into an issue that we have been wrestling with and need some assistance.

Every now and then a report is generated, without throwing errors, that is mostly blank. All it has on it is some text, a logo and a page number; none of which are sub reports. We have error handling all around the code in which does the actual rendering, yet we don't see an exception being thrown. We also check to see if there isn't data for the report before and if there isn't we don't ask the Telerik Reporting library to render anything.

I've attached three images, the first is "blank" report and the second that is populated report. The blank report was generated through our automated process along with other reports. The populated report is one that I generated using the same code but manually outside of the scheduled time in which we "batch" generate reports. These would be considered the same report, because the same parameters were used in the query for the same database.

The third image is the report designer view of the same report -- the top most report.

Thank you for any help you can give us.

Hi all,

I don't know if this is the right forum, but i have a small question bout security of the self-hosted REST service for the reporting viewer.I am using asp.net core and have a few (secured) pages that show telerik reports. These are .trdp files hosted by ourselves and setup according to https://docs.telerik.com/reporting/telerik-reporting-rest-service-aspnetcore-mvc-core3 ... 

This is however a jQuery implementation and from within the code of jquery i can probably easily change the .trdp file name (i use logical names, so not hard to guess) and get a different report. This was not a real big problem, but now certain users should not be able to see certain reports.So this suddenly became a problem. 

Does anybody have an idea what the best approach would be to secure this?

Thanks,

Alexander

When I run my .net core app locally, via Visual Studio the reports work fine. They are generated like they are supposed to
but when I host the app on a server, nothing happens. I don't even get a console error or a warning.

This is my ConfigureServices in the Startup

Here is the view, where my ReportViewer is. I tried with the standard serviceUrl variations "/api/reports" as well as "api/reports" as well as "~/api/reports".

I have no errors in console, in the picture attached.

Anyone has any idea why would it generate the reports just fine locally via Visual Studio and when I host the app it doesn't generate /print the reports?

Hi,

I am looking to create a report and add a graph purely using C#. Is this possible?

For example in C#:

Report report = new Report();

DetailSection section = new DetailSection();

Graph graph = new Graph();

section.Items.Add(graph);

report.Items.Add(section);

....

I am currently trying to accomplish this but the graph does not show. Note, the code I put here is oversimplified and I have setup the report, section and graph (hopefully) correctly. I can get the report to display a Shape but not the Graph.

Can anyone suggest how to correct this issue please?

This is version 14.1.20.618 running in VS 2015 ( not standalone designer)

Error started when I inserted the 'calls' column and it threw this error. I closed the error and continued,

The report runs , but if I try to select the column in the designer then it throws the error each time. ( see screen shot)
I also cannot select the white cell in the totals at the bottom of that column . It just wont let me select it.

That cell renders as part of the Totals to the left ( see PDF of the report when it runs)

Advice greatly appreciated.

Trying to display a report, and give an option to export the report directly to Outlook.

I'm using the HTML5 viewer in ASP.NET MVC, and ideally this would mean the user would click a button at the top beside Download, and this would open up Outlook with the actual report file already attached and ready to be emailed.

Hello,

Does Web Report Designer support Object Data Source?

Hi all,

We are using web designer to edit reports. We have a JSON data sourcewith inline JSON. For a sake of simplicity it looks like this:

When I edit it from standalone report designer:

{
                Name: “Sample Report”,
                Description: “Sample report for testing purposes”,
}

But, when it is opened from web designer to edit, it is showing like this:

{
                Name: "Sample Report",
                Description: "Sample report for testing purposes",
}

You can see that, the quot " sign is replaced with a " . After I put some changes and save it, next time I open it, it looks like this:

{
                Name: "Sample Report Update ",
                Description: "Sample report for testing purposes",
}

You can see that & sign is now replaced with & . Everytime I saw it keeps adding this additional symbols and replacing them. 

When I process the JSON, I am getting the parsing error.

I want to have a principle of WYSIWYG with JSON datasource. Is it a known issue? And how soon it can be fixed?

Thanks,
