Package 'Telerik.Reporting.OpenXmlRendering 19.0.25.313' from source 'https://nuget.telerik.com/v3/index.json': This package is signed but not by a trusted signer.

I am trying to create reports programmatically and when I copied the code from the links there are errors. I am getting the following errors:
'Report' does not contain a constructor that takes 0 arguments
'DetailSection' does not contain a constructor that takes 0 arguments
How can the examples be updated?
Report report = new Report();
string selectCommand = @"SELECT * FROM Sales.Store";
string connectionString = "Data Source=(local)\\SQLEXPRESS;Initial Catalog=AdventureWorks;Integrated Security=True";
Telerik.Reporting.SqlDataSource sqlDataSource = new Telerik.Reporting.SqlDataSource(connectionString, selectCommand);
report.DataSource = sqlDataSource;
DetailSection detail = new DetailSection();
this.detail.Height = new Telerik.Reporting.Drawing.Unit(3.0, Telerik.Reporting.Drawing.UnitType.Inch);
this.detail.Name = "detail";
report.Items.Add((ReportItemBase)detail);
Thank you.

Dear Telerik Support Team,
I am encountering an issue where, after using the setOptions method to update the grid configuration and then loading the grid using getOptions, my custom events, functions, and the Telerik inbuilt editor on columns do not initialize properly. Additionally, the custom filter functionality in the column filter is no longer working after calling setOptions.
I am trying to implement a feature where grid settings are saved on a per-user basis. However, after applying the new settings, the events and filters stop functioning as expected.
Could you please advise on the best solution to ensure that custom events, editors, and column filters are reinitialized properly after using setOptions and getOptions? I would appreciate any guidance on how to address this issue while saving user-specific grid settings.
1st sample which I did and 2nd is the way i want to do it

I am using RadNavigation for my application and currently it looks like this.
I need 2 changes in the above settings.
1. The first level expansion, i. e the Sandwich menu at the top, when the screen is expanded, will be expanded horizontally. I need it to be expanded vertically.
(Currently the main Menu's, Menu 1, Menu 2 etc showing vertically as the screen is not expanded. If the screen is expanded, they will start showing Horizontally.)
2. The second level expansion Menu 2 --> Menu 2.1 --> Menu 2.1.1 is expanding vertically. I want it to be expanded Horizantally as shown in the below image.
How can i achieve this with RadNavigation Menu? Can you please help?

Currently, I am using RadPanelBar in my application.
The expansion is exactly as shown here in the example here - https://demos.telerik.com/aspnet-ajax/panelbar/examples/overview/defaultcs.aspx?_gl=1*1ii0316*_gcl_au*NjQ4MjM2MzI0LjE3Mzc0MTgwNTU.*_ga*MTQwMDI1ODExNy4xNzM3NDE4MDU1*_ga_9JSNBCSF54*MTczODczMzkwNC4xMC4xLjE3Mzg3MzY1NzAuMi4wLjA.
However, I want to change it to look like this -
Can you please suggest if this can be done with the existing RadPanelBar control? If yes, how can I do this.
If not, with which other control I can achieve this?
