I am currently using Telerik Reporting version 15.1.21.616 (R2 2021 SP1) in my ASP.NET application. I noticed that the report viewer only exports to the legacy Excel format (.XLS) and there is no option for Excel (.XLSX) in the export formats.

I have checked the Bin directory of my installation, and I do not see the Telerik.Reporting.XlsxRendering.dll assembly, which I understand is required for XLSX export.

Tried to replicate this with prod clone DB on local, works fine. We are not able to find the cause, please help. Below are some information that can help.

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

Serkan

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.

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
