Hi, I'm developing a report with standalone designer (version 18.2.24.824) with a JSON Data Source. When I put my JSON inline, no problem. But when I follow this instructions, I have no data (I bind my data source on a table). No errors, but no data.

The content of the JSON file :

On my data source, I set the property "Data Selector" as "eleves".

I create a report parameter named "DataSourceFileName".

I run the report (from an ASP.NET Core app) with the follwing value for the parameter : @"c:\\temp\\Telerik report\\Data\\data.json"

My Table in the report has following parameters :

• DataSource : ListeElevesDataSource [Telerik.Reporting.JsonDataSource]
• Telerik.Reporting.Binding : 
•     Path : DataSource.Source
•     Expression : GetUri(Parameters.DataSourceFileName.Value, "Absolute")

Any advice ? Thank you

Hi,

In our report design, we need to add two watermarks depending on . Although through the designer we can add multiple text watermarks they all seem to start from the middle, which makes them overlap if both watermarks appear at the same time. Changing the Orientation also does not work because all the orientations start from the middle.

Is there a way to change the placement of the watermarks so they will no overlap?

Thank you.

I need help using reporting in a Blazor app. I would like to create a report based on a razor page. There will be 3 values and 13 lists of entities coming from the code behind cs file that need to go to the report. This is a .Net 9 application. And I want to display it with the Blazor report viewer.

This would be an object source, and it seems very difficult to do. I cannot use the Visual Studio report designer because that is only for the legacy full Dot Net framework. I am trying to use the standalone version. Is there an up-to-date example of doing this in a Blazor application?

I just added a blank report in VS2022, but I don't see a way to add report items like label, images text boxes etc.  How do I design it?  Thanks!

Is there a limit on the number of RunningValue() functions we can use in the same scope (group) as I have 3 and the first one behaves as expected, the others don't produce the expected result. 

I've copy and pasted the working one, to replicate it and the replication doesn't work, so it seems like there is a limit but I can't really understand why there would be. 

this works

=RunningValue("group1", sum(Fields.value))

this doesn't work

=RunningValue("group1", sum(Fields.volume))

For reference what I'm using the RunningValue() in expressions for accumulated date in text boxes

Eg

Value, Volume, Accumulated Value, Accumulated Volume

Hi all - we have a website which uses Telerik Reporting, setup as a REST webservice - we have a backend api which makes calls to the Telerik service.

We have 3 separate environments - DEV, STAGING and PROD, of which only PROD is giving us problems.

Thought it might be a firewall issue, but now thinking something is interfering with the REST service - after tracing a few calls, the client id is created and given back, but often when we send it to get a report, we get an error that the client is is "not found" and "expired".

I've also seen it get PAST this part, go ahead and generate the report, then give back the ID, but when we make the call to fetch the report document, we get a "gone" error.

It seems like a session is started when the client 1st gets the client ID, but does not stay alive, or is being killed, before we can do anything.,

I HAVE ALREADY SET ClientSessionTimeout - tried setting it to 16 minutes, but the call to api/Reports/clients/sessionTimeout ALWAYS return 960 - ???

I'm thinking it's maybe some Azure Application Service setting, but I'm not the one who would check, I'm just a programmer, hoping to have some ideas to pass along to the Azure team here.

Thanks!

Dear Support,

I am getting below error while implementing page numbers below

= 'page ' + PageNumber + ' of ' + PageCount

Thank you,

I report that crashes if there are more than 10 or so pages.  I have simnpified this report so it has no formatting, no grouping and only one field of data.   I have made this report as simple as I can.

When I run the report I get the error below.

{"message":"","exceptionMessage":"One or more erro…ype":"DocumentRenderException","stackTrace":null}', _error: '', _responseJSON

If I run the same report but filtered for fewer pages, it works fine.

"How can I get continuous serial numbers (1, 2, 3, 4, etc.) in a grouped table with 12 columns? Currently, the 'Column()' is only displaying 1. How can I generate a proper serial number for the grouped table?"
