Hello Supports,

I want to try and install Nuget packages Telerik.Reporting.Services.AspNetCore for my Asp.net Core project but it isn't found.

when I go to the option "Manage Nuget packages", these are no available the packages to download (see the attached file).
Is it missing from the private nuget feed ?

Thank You.

Hello Telerik Reporting Community,

We have released a new version of Telerik Reporting today, 2024 Q1 (18.0.24.130). Please update your existing installation at your earliest convenience.

You can review the Legacy Installer Vulnerability - Telerik Reporting article to learn more details about why we are recommending customers to update.

To get the new version, take the following steps:

1. Go to Downloads | Your Account. 
2. Select Telerik Reporting.
3. Download the msi installer file, run it, and follow the steps to completion.

Notes

As the KB article explains, the issue pertained only to the old installer component, and not Telerik Reporting contained within the installation package. It does not affect any applications you’re using Telerik Reporting with.

If you have a rare situation where you cannot update the PC installed version, there are various ways to keep a project using an older version of reporting even though the PC has a newer version installed.

• NuGet Option: Update your projects to use the Telerik Reporting NuGet packages, instead of local DLLs (see https://docs.telerik.com/reporting/getting-started/installation/installation-approaches#using-nuget-packages).

• Copied Assemblies Option: Copy the older version’s DLLs to the project directory, then update the project references to use the copied assemblies (instead of the assemblies in C:/Program files (x86)/Progress/Telerik Reporting [older version]/)

We highly recommend you open a Technical Support Ticket if you have a complex situation and would like to ask questions before updating the PC’s installed version. You can open a Support Ticket here => https://prgress.co/DevToolsSupport.

I'm having issues with hiding or disabling the Search button on the Report Viewer. 

I found the attribute here for the Search Dialog:

https://docs.telerik.com/reporting/embedding-reports/display-reports-in-applications/web-application/html5-report-viewer/api-reference/data-attributes

I found this link on how to disable a button in the Viewer:

https://docs.telerik.com/reporting/knowledge-base/hide-or-change-html5-report-viewer-toolbar-buttons

But when I try it, the Search button continues to be active.

This is the code I have below. I would also point out that the reason I am trying to hide the Search is because when I do try to a search, I get a bunch of gobbly-gook that appears in the results. See attached. I'm not sure what that is all about. So I am willing to keep the Search button active as an alternative if there is a way to return clean results.

I am using reporting 15.2 in Sitefinity 14.3, works great

Updated to sitefinity 15.3 copied over all the reporting assemblies and now it's throwing this error

Cannot access the Reporting REST service. (serviceUrl = '/api/reports/'). Make sure the service address is correct and enable CORS if needed. (https://enable-cors.org)

It's clearly not CORS related, but the 404 not found is weird.  Any thoughts?

Hi support team.

I go back to you on this subject because I have a problem as below:

I'm using Telerik Report Designer Standalone for making my report template.

In fact, I have 2 series: 1 barserie and 1 lineserie. In Line serie, I can make any style of DataPointLabel without any problem. However in bar serie, I want to change the color of DataPointLabel as below but it doesn't take in affect, please help me to resolve it

Hi team, please help to check this error

Afer update to the newes Version , the context menu spans the full width of the window. see screenshot. its not possible to click a submenu.

how can i fix this?

The Native Blazor Report Viewer uses Blazor Multiselect by default for multiselect parameters. This becomes very cluttered when many items are selected.

I want to display parameters in a multi-select dropdown list with check boxes, exactly like this: https://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/checkboxes/defaultcs.aspx

The equivalent Blazor demo is more cluttered as selections showing in the select box: https://www.telerik.com/blazor-ui/documentation/knowledge-base/multiselect-checkbox-in-dropdown 

The article here https://docs.telerik.com/reporting/embedding-reports/display-reports-in-applications/web-application/native-blazor-report-viewer/customizing/how-to-create-custom-parameter-editors has an example on how to customize the parameter widget in Native Blazor Report Viewer.

Can anyone here share the code to create a nice clean multi-select dropdown list with check boxes for a parameter in the Native Blazor Report Viewer? 

Hi Telerik reporting support team,

We are looking for a solution to draw 2 series of chart in the same Graph: LineSeries and BarSeries. We did it successfully in Telerik WPF but not in Reporting.

In WPF, we can draw 2 series with 2 datasources in the same Graph.

In Reporting, we tried to draw 2 graphs, the bar overlays on line, but unfortunately, they are not positioned in the same scale (see picture).

Do you have any suggestion to us to achieve this behaviour?

Many thank for your help,
