I have a data source that has geo-coordinates in each record. 

I want to make a request to an API to generate a map out of these geo-coordinates using their static map feature.

To do this I need to aggregate multiple fields in a record and then aggregate these values (from each record) together to form a URL that I can use to populate an image component.

 

I've been able to use the aggregated functions like sum and count but as soon as I try to use Join(", ", Fields.x) I get the error

An error has occurred while processing TextBox 'textBox53':Type mismatch in function arguments. Cannot find an overload of the function Join() that accepts arguments of type (String, Double).

If I use Join(", ", CSTR(Fields.x)) I get the error 

An error has occurred while processing TextBox 'textBox53':Type mismatch in function arguments. Cannot find an overload of the function Join() that accepts arguments of type (String, String).

But if I use Count(Fields.x)

I get the value 9 which is correct.

Why can I use some aggregated functions on a field but not others?

Hi All,

We are implementing Web Report Designer in our project. There is Telerik Reporting service is running as a separate service (in Azure VM), our server-side project is also running in k8s which communicate to the Reporting service through gRPC. The Reporting service has custom implementation for IReportSourceResolver (for report preview) and IDefinitionStorage (for report design). We store xml content of a report file in the database that is beside of out server-side project. In the middleware of our project, we need to send report xml content. The problem we have is that xml string is too long and has unsupported characters to be used in Uri.

If you set just Telerik report file name (for report parameter in webReportDesigner.html), then it works. See CustomReportDefinitionStorage class in the picture below. That GetAsync() method works only when you send just report file name. But it doesn't work when you send entire report content as a XML string. Is there any solution or workaround to do this with report xml? Is there a way to do with POST query?

 

Thanks!

Hi,

I have built a report on the Telerik Standalone Report Designer, it calls a stored procedure and the SP will complete by around 5 minutes 33 seconds.  I have specified the Connection Timeout to 600 seconds in the Connection String (see attached), but when I preview the report on Telerik Report Designer and Telerik Report Sever, I still got the error message "Execution Timeout Expired.  The timeout period elapsed prior to completion of the operation or the server is not responding.".

How could I resolve this problem?

Many thanks.

Best regards,

Jocelyn

I wish to integrate a telerik report viewer into a blazor application (I am using Dot net 6.0).. I have set up a Reporting Server also using Dot net 6.0
I wish to use Oracle db as the data Source of my application
I have tried the following steps

1.Opened the default Telerik.ReportDesigner

2.Clicked on new and added the datasource

3.Selected Sql Data Source

4.Clicked on build new connection and selected OracleClient Data Provider

5.Chose build option

6. In the Data Source clicked on change and selected  .Net Framework Data provider for Ole Db (as the other one is shown as deprecated)

7. Filled the feilds and when cliked on test connection, it is showing " The  'MSDORA' provider is not registered on the local machine"


I looked into the issue and tried shifting to Telerik.ReportDesigner x86 application

I followed the same steps as above and when i clicked on "test connection", it is showing an error  "Oracle client and networking components were not found. These components are supplied by Oracle Corporation and are part of the Oracle Version on 7.3.3 or later client software installation.Provider is unable to function until these components are installed"

which application should i use and is there any solution to get rid of this error
Kindly provide as solution for this
I am using Oracle Db version "Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production"

my connection string is like "Data Source={111.111.1.11:2222};User Id={useid};Password={pass}"

Hi Team,

I have created the Telerik report (.trdp) to show some data in Line Chart with below details.

Chart Type : Line Chart

Series : LineSeries

LineType : Smooth Line

YaxisScale : Numerical Scale.

Xaxis Scale : DateTime Scale

I have exported the PDF from Telerik Report designer  and it is working fine i.e, Line Type is smooth throughout . However , when I integrate the telerik report in my Asp.net Web api I started getting following issue. Line series is partially Smooth for continuous values and straight Line for missing values. Please let us know the solution to make the entire line type smooth.

PFA Screen shots for issue.

Thanks

Hello,

I implement reports and use IReportSourceResolver. When report viewer asks for a report, the method is called 3x. I need to load data into the report using objectDataSource. But the problem is that the parameters from currentParameterValues are loaded only in the first call (OperationOrigin.ResolveReportParameters). In the other two, the variable is already empty. Can you please help me? 

Thank you

public ReportSource Resolve(string uri, OperationOrigin operationOrigin, IDictionary<string, object> currentParameterValues)
        {
            var reportPackager = new ReportPackager();
            var report = Construct.CommonManager.Report.GetModelFromUri(uri);

            if (report == null)
            {
                throw new FileNotFoundException();
            }

            MemoryStream stream = new(report.Data);
            Telerik.Reporting.Report report1 = (Telerik.Reporting.Report)reportPackager.UnpackageDocument(stream);
         
            var instanceReportSource = new InstanceReportSource
            {
                ReportDocument = report1
            };

            if (operationOrigin == OperationOrigin.ResolveReportParameters)
            {

            }
            else if (operationOrigin == OperationOrigin.CreateReportInstance)
            {

            }
            else if (operationOrigin == OperationOrigin.GenerateReportDocument)
            {

            }

            return instanceReportSource;
        }
