Change the Font Name of a TextBox from Arial to Calibri

Go to another TextBox and change the Font Name from Arial to Calibri.

This is the error I get: "Could not change the property 'Name'. Name 'Calibri' already exists."

The same error occurs when trying to change multiple TextBoxes at once.

The Could not retrieve Expression schema. error can be experienced while trying to set a value of textbox by using the expression editor.

When a Report with ObjectDataSourceParameter is loaded into the WebReportDesigner, the designer throws an error when trying to initialize the parameter.

Could not create instance of 'ObjectDataSourceParameter'. TypeError: Cannot read property 'push' of undefined

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]

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

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.

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:

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 configuring a WebServiceDataSource in the Web Report Designer in ASP.NET,  upon previewing the data there is an error '404 Not Found". The same web service was successfully resolved by the Standalone designer and in the ASP.NET Core demo.

The data source fields were visible and usable in the designer also under ASP.NET Web Report Designer.
