Steps to reproduce:

1.Download and run the project

2. If the scaleMode is FitPage, the report doesn't appear

3. If the scaleMode is FitPageWidth, the UI seems to be broken

You can check the attached video for further reference.

Steps to reproduce:

1. Download and run the attached project in IE or Firefox

2. Write in the field for example "haha" and click the button.

3.Scroll down and you will notice that the headers are not frozen.

Steps to reproduce the issue:

1. Create a new report in the WebReportDesigner;

2. Add a simple CSV DataSource (for example with Item and Value columns);

3. Select the Table Wizard and set the CSV DataSource as a Value of the DataSource property;

You will notice that the names of the columns from the datasource are missing.

The issue occurs when a report contains a subreport with InstanceReportSource set as its ReportSource. If the report definition in this InstanceReportSource contains data sources, they will be serialized as DataSourceRef objects instead of using their actual type names like EntityDataSource, CsvDataSource, etc.

The issue is reproducible only in Standalone Report Designer, i.e. serializing/deserializing the report definition programmatically would work as expected.

The issue is introduced in Telerik Reporting R1 2019.

When editing an existing SQL data source from stored procedure, the "@" before the parameter name got dropped. Causing the report not passing the report parameter value to the query parameter

2020 R2

I have a Custom Csv Export class that implements IRenderingExtension. This works fine when the ReportServiceConfiguration.Storage is set to an instance of FileStorage or MsSqlServerStorage.

When using RedisStorage, after clicking on the CSV option from the Html5 Viewer's menu, the browser redirects to a new url to display the following error message:

{"message":"An error has occurred.","exceptionMessage":"Buffer cannot be null.\r\nParameter name: buffer","exceptionType":"System.ArgumentNullException","stackTrace":"   at System.IO.MemoryStream..ctor(Byte[] buffer, Boolean writable)\r\n   at System.IO.MemoryStream..ctor(Byte[] buffer)\r\n   at Telerik.Reporting.Services.WebApi.ReportsControllerBase.GetDocument(String clientID, String instanceID, String documentID) in C:\\DeveloperTooling_Reporting_Agent1\\_work\\17\\s\\Source\\Code\\Telerik.Reporting.Services.WebApi\\ReportsControllerBase.cs:line 305\r\n   at lambda_method(Closure , Object , Object[] )\r\n   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.<>c__DisplayClass13.<GetExecutor>b__c(Object instance, Object[] methodParameters)\r\n   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.ActionExecutor.Execute(Object instance, Object[] arguments)\r\n   at System.Web.Http.Controllers.ReflectedHttpActionDescriptor.<>c__DisplayClass5.<ExecuteAsync>b__4()\r\n   at System.Threading.Tasks.TaskHelpers.RunSynchronously[TResult](Func`1 func, CancellationToken cancellationToken)"}

The debug console in Visual Studio shows this error:

Failed to load resource: the server responded with a status of 500 () [https://localhost:44350/api/reports/clients/9bbda764fa6/instances/722eb62b3a9/documents/969b05177e4f00b24938d1?response-content-disposition=attachment]

Currently, you may aggregate values from a certain scope for a particular page with the Page function PageExec. It would be great to be able to display also the carryover aggregates up to the current page. 

For example:

We create many legal forms, which use nested ordered lists. In htmlTextBox for reporting, we'd like to apply styles like upper-alpha, lower-alpha, etc to the ol tag. Currently, the only numbering for an ol is 1, 2, 3. CSS ability to set the style at depth (like ol ol) would be best.
<ol>
<li>1. text</li>
<li>2. text
  <ol>
  <li>a. text
     <ol>
          <li>i. text</li>
          <li>ii. text</li>
      </ol>
  </li>
  <li>b. text</li>
  </ol>
</li>
</ol>

If a table-based item (Table, List, Crosstab) does not fit in a single page and needs to occupy more than one page, its bottom border is not drawn on the first page and its top border is not drawn on the second (subsequent) page. This behavior is by design and its purpose is to help the users visually distinguish the table as a single item. The table has only one top and bottom border and they are displayed at the beginning and at the end of the table, regardless how many pages the table actually occupies.

Since users might find this confusing, a table should have a property controlling this behavior. The default state of the property will preserve the current rendering. If the user explicitly sets the property, then the table will draw its top and bottom borders on every page it occupies.

1. webServiceDataSource1URL - For the Service URL we are using the inline variable "@url" and for Value and design time value we are using the "https://services.odata.org/TripPinRESTierService/People"

2. webServiceDataSource2NoURL - For the service URL we are directly using the "https://services.odata.org/TripPinRESTierService/People"

In scenario #1 there occurs an error "An error occurred while loading the data schema for 'webServiceDataSource1URL': unexpected token | in JSON at position 0".

The fields for #2 are loaded and for #1 are not.

We use telerik reporting service in ASP.NET Core 3 on CentOS 8 server.
I just confused in spesific kanji is not show in preview and pdf.

"備考" is not shown,but "考備" is shown, reason why?(see attached xslx file)
Private Font settings will be fine(see attached reportsettings.json),because of gothic and mincho font is displayed.
If set double byte space ("備考　") is displyaed... I dont know reason why.

We install libgdiplus API in cent OS server, but not well.
hiragana is OK, but some types of Kanji is Not OK.

We already running on Windows server is not having same issue(always displayed)

We think some issue in textbox sizing algorythm in Telerik Reporing on Linux ( I used latest version 14.2.20.916)

We look forward to hearing from you.
