Hi Technical team,

I added a parameter in a report parent by following this link: https://docs.telerik.com/reporting/designing-reports-parameters-adding-parameters

I let all the values by defaults.

Then, I tried to pass the parameter to a SubReport under the parent report by following this link: https://docs.telerik.com/reporting/report-items-sub-report

All I did is in Report Designer.

However, after that the parent report is initiated, I found the value of parameters always null or empty.

Could you tell me where I did wrong?

Many thanks,

Hi,
I'm having trouble extending Report Designer with User Function.

I've created an assembly with 3 functions the following code:

using System;
using Telerik.Reporting.Expressions;


namespace ReportLib
{
    public static class SVFunctions
    {
        [Function(Category = "My Functions", Namespace = "ReportLib", Description = "Duration")]


        public static string Duration(DateTime Start, DateTime End)
        {
            TimeSpan ts = End- Start;
            double Ore = ts.TotalHours;
            double Minuti = ts.TotalMinutes - (Ore*60);
            double Secondi = ts.TotalSeconds - (Ore*60) - (Minuti*60);
            return string.Format("{0:0}:{1:0}:{2:0}", Ore, Minuti, Secondi);


        }

        [Function(Category = "My Functions", Namespace = "ReportLib", Description = "ToLocalTime")]
        public static DateTime ToLocalTime(DateTime utc)
        {
            return utc.ToLocalTime();
        }


        [Function(Category = "My Functions", Namespace = "ReportLib", Description = "Adesso")]
        public static string Adesso()
        {
            return "12/12/2014";
        }
   }

I've added the reference of the assembly inside the ReportDesigner config file.

<Telerik.Reporting>
     <AssemblyReferences>
         <add name="ReportLib" version="1.0.0.0" />
     </AssemblyReferences>
</Telerik.Reporting>



I've created a report and with a text field using an expression that references to the function Adesso() as you can see in to the attached picture.

When I run the report I've the following error (shown into the picture)
An error was occurred while processing TexBox 'xxx'. The Expression contains object 'ReportLib' that is not defined in the current context.

What's I'm doing wrong

Hi,

is there a working example of Telerik Reporting used in Blazor WebAssembly? I've only found server-side Blazor examples.

Thanks.

Hello,

We have a web site hosted in Azure, and we are trying to add Telerik report generation to it. It works just fine when running in Visual Studio, but when we publish it to Azure and run it from there, we get the below error.  I realize this is a very generic question--I don't have a little test project that I can provide--but does this symptom sound familiar to anybody?  A known issue with deploying Telerik.Reporting to Azure, perhaps?

Using Telerik Q1 2014.

Method in Question:

            try
            {
                var monthlyInvoice = new Reports.MonthlyInvoice(model);
                var reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
                var generatedReport = reportProcessor.RenderReport("PDF", monthlyInvoice, null); //*** where it crashes
                return generatedReport.DocumentBytes;
            }
            catch (Exception exp)
            {
                Tracker.TrackError(exp, ErrorTrackerTags.Report, ErrorTrackerTags.Invoice);
                return null;
            }

The Error:

Hi team,

I want to exclude export options (Exel ,RTF, TIFF, Web arhive) from Report designer's telerik ribbon . I can do this from web.config file but its getting excluded from other pages as well, I just wanted to exclude these options from single  page report not from all pages of my project.

Anyone can help me asap?

Kind regards,

Payal

 

There appears to be a bug with the CSV Data Source in the Web Report Designer - There are 3 options listed:  Upload CSV file, Use existing CSV file and Use CSV Inline.  When selecting the 'Use CSV Inline' option the forms keeps either "Upload ..." or "Use existing ..." selected and continues to validate for the missing file.

Is there a way to delete report definitions in Web Report Designer? I notice that when creating a custom definition storage, the interface "IDefinitionStorage" implements a "DeleteDefinition" function, so I'm assuming there is a way to do so. My first thought was the "file menu" would contain a delete option but it does not seem to be there.

Is it possible to have asymmetric margins on a report? That is, the left margin of the odd pages must be greater than the right, and the right margin of the even pages must be greater than the left margin. This is because the report will print on both sides of the sheet, with a long margin on both sides. This long margin will serve to physically file the document.

Maybe this capability is already present, but, I am unable to find it.  When text overflows a text box and the text box is not allowed to grow, I need to be able to show an ellipsis or the remainder of the text that can fit. Currently the report removes all words that can not fit in the given area.

 It would be very helpful if we could set a few overflow options like "ellipsis", "truncate" (default), or "clip". Example

• Original: "Hello Telerik Reporting"
• Truncate: "Hello Telerik"
• Ellipsis: "Hello Telerik Repo..."
• Clip: "Hello Telerik Repor"
