When a report contains data item bound to big amount of data, it takes time to export in CSV format due to data denormalization. This would be a performance improvement for big data reports.
With reference to support ticket 992325 where the behaviour of making minute changes to the measurements of grid columns occurs inadvertently I would like to suggest that this is changed and does not happen, i.e. improve the handling of floating point numbers in the serialization/deserialization process. It causes noise in the source control history of the file. Note that this behaviour is not apparent with comparable reporting solutions, e.g. SSRS/RDLC files.
The expression parser throws an exception when parsing an expression that calls .ToString() method after closing parenthesis like the one below:
=(Fields.Value1+Fields.Value2).ToString()
If the two operands in parentheses are converted to double, the expression is parsed and evaluated correctly:
=CDbl(Fields.Value1+Fields.Value2).ToString()
There is the newly introduced WebServiceDataSource which enables me to get JSON data from a web service. I'd like to be able to use JSON as a data source for a report without using a web service. For example, the JSON might be embedded inside the report definition, or it might be coming from an external text file (URI or URL), or even pass it programmatically to the report at run-time.
Add support for PDF Accessibility as described in the https://www.adobe.com/accessibility/pdf/pdf-accessibility-overview.html
In my report, I use font SimSun to display Chinese, when preview it's OK, but after click print, an exception is thrown.
Internal Server Error

Then I change ReportsController to the Reports directory above.
When Run it in IIS, it's OK, but when check into Docker, there is an exception thrown.

As Heat maps are not supported by Telerik reporting, Could you please let me know if you have workaround solution readily as a demo . If not please suggest the which third part libraries to be used in C# solution.
