Hi Guys,
mit Blazor Wasm project is working localy.
So i published it on the server and run the ReportViewer:
Unable to get report parameters. An error has occurred. Type: Telerik.Reporting.ReportSerialization.Current.ReportSerializable`1[Telerik.Reporting.Report]
In Browser Dev:
The Server was a Linux Server with Docker. I installed
sudo apt-get update sudo apt-get install -y libfreetype6 sudo apt-get install -y libfontconfig1
sudo apt-get install libc6-dev sudo apt-get install libgdiplus
added this: Telerik.Drawing.Skia
and
RUN apt-get update \
&& apt-get install -y --allow-unauthenticated \
libc6-dev \
libgdiplus \
libx11-dev \
&& rm -rf /var/lib/apt/lists/*
so all packages installed like tutorial and another forum posts i found. I used the demo all same. have someone an idea?
Best Regards

Im getting the "single-row subquery returns more than one row" error when using a stored procedure as a datasource.
This is the beginning of the procedure that I am calling from the report:
create or replace PROCEDURE get_idoc_report (
pStart_Date IN DATE,
pEnd_Date IN DATE,
pPrepMethod IN VARCHAR2,
pAnalyticalMethod IN VARCHAR2,
pInstru IN VARCHAR2,
pMatrix IN VARCHAR2,
pPrepAnalyst IN VARCHAR2,
pAnalyticalAnalyst IN VARCHAR2,
pWO IN NUMBER,
pWO_ID IN VARCHAR2,
pAR IN VARCHAR2,
p_cursor OUT SYS_REFCURSOR
)
IS
BEGIN
OPEN p_cursor FOR
select distinct
to_char(sysdate, 'MM/DD/YYYY') as Current_Date,
to_char(pStart_Date, 'MM/DD/YYYY') as WO_Start, ......
I have run the procedure in SQL Developer using a record to get data from the cursor, and it returns the expected number of data rows. I have used the same query as a Text select datasource query in Telerik and it worked. Any idea why I am getting the "single-row subquery returns more than one row" ? I am thinking Telerik Standalone is not able to access the rows returned from the sys_refcursor output. Any help is appreciated. I have attached the procedure text and a screenshot of the datasource setup.
Using Telerik Report Designer Version 17.1.23.606 and Oracle Database 19C.

We have updated our enterprise SPA application to the latest Angular 20.
Does Native Angular Report Viewer - Kendo UI for Angular support the latest Angular 20?
I have a table that is grouped by the field CellWCCode. The SQL Query is returning multiple rows (one each for the child item in the BOM), so for example, I might get 5 lines per CellCode. The field StdLabCost returns the one item for each grouped item, but now I want to total the StdLabCost for all of the CellWCCode. I have not figured out how to Sum all of the distinct values.
I attached sample data and the report.
Hi,
I have a ReportViewer on my XAML page:
<tr:ReportViewer x:Name="LevelAccuracyReportViewer"
ReportSource="{Binding LevelAccuracyReportSource}"
Margin="520,360,20,20">
</tr:ReportViewer>
It works ok the first time the page is displayed, but if I update the Source a 2nd time:
LevelAccuracyReportSource = new InstanceReportSource
{
ReportDocument = levelAccuracyReportDefinition
};
I get an "Object Reference not set to instance error", but then it works.
If I update the source again, I get the error message twice, then it works.
Each update causes an additional message to be displayed
I'm using the 2025 Q2 release of Telerik Reporting
We want to add a ReportParameter that is visible to the user (We know how to make them visible, we do that with boolean type parameters so the users can hide or show items on reports), that is INTEGER based that will control the number of records are showing in a "LIST" control on our report. For example, we have a detailed Report with USER information; then in the report, we have a list that displays the USER's access over time. This could be one record or as many as a thousand records. We would like is this parameter to control the number of records shown in that list control.
Now, I have been able to create the INTEGER Report Parameter and make it visible; however, what I have not figured out is the following:
TIA
Hi team, what is the way to use the reporting feature in my net core mvc application using jetbrains ride?
