Does Telerik Report Designer Support a Single Date Range Parameter (Like Kendo DateRangePicker)?

Hello Telerik team,

I am currently working on a report using Telerik Report Designer, and I need to allow users to filter data based on a date range (i.e., "from" and "to" date). In Kendo UI, we have a convenient DateRangePicker component that allows selecting both dates in one UI control.

My question is:
Does Telerik Report Designer support a single “date range” parameter, or do we need to use two separate parameters? DateTime parameters (e.g., DateFrom and DateUntil) to simulate this functionality?

Is there any built-in way to do it using one parameter, or a recommended approach to simulating a range? Please let me know.

Regards,

Make Line Chart Labels Clickable to Toggle Series Visibility in Telerik Report Designer

Hi Telerik Team,

I’m designing a Telerik Report Designer report that includes a line chart with markers. I want to replicate a feature that exists in Kendo UI line charts, where:

Clicking on a legend item toggles (hides/shows) the corresponding series in the chart.

This is especially helpful when multiple lines are present, and users want to focus on specific data. Here’s an example screenshot of the chart I’m working with:

My questions:

Does Telerik Reporting support interactive legend click behavior similar to Kendo UI Charts?
If not directly supported, is there any workaround that can help achieve this functionality?

Dynamic Web Service Domain Configuration in Telerik Report Designer & Server

Hi Telerik Team,

I am designing a report using Telerik Report Designer and have connected multiple Web Service Data Sources that require 2-step authentication.

The reports are stored on the Telerik Report Server and are displayed in my ASP.NET MVC project using report server credentials and the report path (Category/ReportName). I have created the following function to connect to the report server:

using System.Web;
using System.Web.Mvc;
using Telerik.Reporting;
using Telerik.ReportViewer.Mvc;
using System.Collections.Generic;
using System;

namespace Project.Extensions
{
public static class ReportExtension
{
public static IReportViewerBuilder GetReportViewerConfig(this HtmlHelper htmlHelper, string reportId, string reportSource, Dictionary<string, string> reportParams)
{
var uriReportSource = new UriReportSource
{
Uri = reportSource
};

foreach (var param in reportParams)
{
uriReportSource.Parameters.Add(param.Key, param.Value);
}

return htmlHelper.TelerikReporting().ReportViewer()
.Id(reportId)
.ReportServer(new ReportServer()
{
Url = ReadConfigData.REPORT_SERVER_URL,
Username = ReadConfigData.REPORT_SERVER_USERNAME,
Password = ReadConfigData.REPORT_SERVER_PASSWORD
})
.ReportSource(uriReportSource)
.ViewMode(ViewMode.Interactive)
.ScaleMode(ScaleMode.FitPageWidth)
.PersistSession(false)
.SendEmail(new SendEmail { Enabled = true })
.Parameters(new Parameters
{
Editors = new Editors
{
MultiSelect = EditorTypes.ComboBox,
SingleSelect = EditorTypes.ComboBox
}
})
.EnableAccessibility(false);
}
}
}

Scenario: My API domain is https://abcapi.com, which is used in every report under the "Configure Data Retrieval" window of the Web Service Data Source.

My Requirement: If the domain name changes, I have to manually update the domain in every report and each Web Service Data Source, which is time-consuming and inefficient.

Question: Is there a way to set the domain name dynamically, so that I only need to update it in one place? Also, where is the configuration of each Web Service Data Source stored — is it in the database or somewhere else?

Prabesh Shrestha

Issue with NuGet Package Download While Integrating Telerik Report Server in .NET Project Using Jenkins

Hello,

We are attempting to use the Telerik Report Server for our project. We have installed the Telerik control panel on the server and also hosted it. The Telerik Report Server is connected to our project in the .NET application. However, while building the project with the Telerik Report Server, we are unable to download the required nugget packages for the project. This issue was encountered on January 30, 2025.

What did we do?

Step 1. We managed the Telerik credentials in the NuGet config file, as mentioned in the following URL: https://docs.telerik.com/aspnet-core/installation/nuget-install. The configuration added is as follows:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>

<clear />
<add key="nuget" value="https://api.nuget.org/v3/index.json" />
<add key="telerik" value="https://nuget.telerik.com/v3/index.json" />
</packageSources>
<packageSourceCredentials>
<telerik>
<add key="Username" value="telerik account email" />
<add key="ClearTextPassword" value="plain text password" />
</telerik>
</packageSourceCredentials>
</configuration>

Note: We found no issues with the credentials.

Step 2. We are using Jenkins (auto-deployment) to download the NuGet packages for the project to build also. The following command was used, but it resulted in an error stating that the packages could not be downloaded from the source.
nuget.exe restore "source\Leslinq.sln"

Running the same command in the local command prompt results in the same error, as shown in the Jenkins console log.

Here is a sample of the error log, and the attached files contain additional details:
********************************************************
https://api.nuget.org/v3/index.json: Unable to load the service index for source https://api.nuget.org/v3/index.json.
An error occurred while sending the request.
Unable to connect to the remote server
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 103.211.149.24:443
https://nuget.telerik.com/v3/index.json: Package 'SQLitePCLRaw.core.2.0.4' is not found on source 'https://nuget.telerik.com/v3/index.json'.
************************************************************

Step 3: We are unable to proceed due to the "service unavailable" error message.

Could you please advise on how we can use the Telerik Report Server with our .NET project and automatically build it using Jenkins?

Thanks!

Regards,
Prabesh Shrestha

Stockchart missing the last point in navigator

I’m working with a stock chart that has a navigator, but I’m running into two issues:

The endpoints of the navigator are being cut off.
The time intervals on the navigator appear uneven, even though I’ve set the baseUnit to "minutes" and the baseUnitStep to 30.

I’m not sure what’s causing these problems. Any help would be appreciated! Thanks!

Issue with Telerik DataGrid Cell Style

In our WPF project, we have an issue with the Telerik data grid that,

> We have implemented a cell style for setting the background colour based on condition by using the MultiValue Converter,

Style code:

Converter code:

public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
if (values[1] is ArcFlashEvalRecord)
{
Efx.Assert(values[1] is ArcFlashEvalRecord && (values[1] as ArcFlashEvalRecord).pData != null, "FIX THIS - expecting ArcFlashEvalRecord and ArcBusData");
GridViewCell cell = values[0] as GridViewCell;
ArcFlashEvalRecord record = values[1] as ArcFlashEvalRecord;
GridViewColumn column = cell.Column;
if (column != null)
{
AF_FieldType field_type = (AF_FieldType)column.GetValue(AttachedProp.TagProperty);
return AFCellInfo.GetCellInfo(field_type, record).BgBrush;
}
}
return null;
}

Issue: The issue is the background colour is not set properly for each cell.

Description: Initially the data is loaded and the Telerik data gets rendered in the display, we have more than 10 columns, and some of the last columns are hidden. Initially, the background colour worked properly for all cells. but when we horizontally scroll to the end of the data grid to see the hidden columns, at that time, the background of the cell is not set properly, it randomly sets the background colour for hidden column cells. it's changing every time we scroll.

RadDocument: IOException while exporting the document to byte array

I am currently experiencing an I/O exception when trying to export the RadDocument to a byte array using the Telerik.Windows.Documents.FormatProviders.Pdf.PdfFormatProvider.

Here is a code snippet of how am I using the Provider:

PdfFormatProvider pdfProvider = new PdfFormatProvider();

_printReportByteArray = pdfProvider.Export(_printReportDocument);

using (var memoryStream = new MemoryStream(_printReportByteArray))
{
    this.PrintReportViewer.DocumentSource = new PdfDocumentSource(memoryStream);
}

The exception occurs at

pdfProvider.Export(_printReportDocument)

It appears that the provider is trying to load the font file from the Windows directory, but for some reason this particular file is causing the exception randomly on certain machines (not on all machines). I would like to know if there is a way to resolve this issue. Like loading the font file into the memory instead of relying on the Windows directory.

Note: the font file does exist at the provided path location, and is not missing.

Here is the full exception message:
