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.

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

When a report is rendered by the REST Service, and that report has an element with applied 'Navigate To Report'-action, the full path of that file is being used as a reference, instead of a relative path or just the report-name.

Hello Team,

I will be great if the Telerik Reporting REST Service Core could support System.Text.Json serialization.

Best Regards,

Feature Request - Show email sent / error notification using the report viewers built-in notification system. 

It would be nice to have an option to have a message shown when the email with the report is sent or if there was an error sending.
Right now when you hit email and send the user does not know if it was successful or not. Being async is nice but I have noticed that it could take a few seconds to complete and if the user navigates away from the report viewer during this time the report has the possibility of not sending. Either way right now the user has no definitive method of knowing if the email was sent or not.

Currently, you need to add the Web Report Designer manually following the steps here:

https://docs.telerik.com/reporting/web-report-designer-setup-in-net-core

https://docs.telerik.com/reporting/web-report-designer-setup-in-dot-net-framework

It would be nice to have templates in VS as an easier way of adding the Web Designer.
