I am rendering a report with multiple large images in PDF. The rendering fails with the following error:
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.

When trying to duplex print a report that has odd page numbers, the next report's first page prints on the back of the previous report. We need the ability to conditionally insert a page break based on whether the report's (the group's) page count is odd or even. Since we don't have access to the global pagecount variable outside the footer, there is no way to use it to insert a page break into the body of the report. This seems like it would be such a common need with the desire by many to save paper that it would be an obvious feature to include in the product. Thanks.
When applying the property Docking with either of the following values will cause the Visual Studio Report Designer to squeeze the table down to 0 width:
While the value 'Right' will cause the table to be rendered outside of the report-section on the left side. This is reproducible with the example report CryptoCurrencies.cs.
The ObjectDataSource component in the Web Report Designer does not have complete design-time support. The major things that are missing:
It would be very helpful for us people that have been using Telerik Reporting in Silverlight (or WPF) applications to have access to a Report Viewer for Windows Store Apps (XAML). The future of Silverlight is unclear at least and there are many Line Of Business Applications currently running under Silverlight and I know of many developers that are looking to port their LOB apps to Windows Store Apps (or Universal Apps). The current HTML5 Report Viewer does not provide printing when it is implemented in browser window in Windows Store Apps so we cannot really offer this option to our customers.
I have projects on .NET Core and I want to use the System.Text.Json serializer that is the new default, but reporting relies on Newtonsoft.Json.

ADMIN EDIT
There are two approaches that can be taken right now to solve this:
OPTION 1: define separate endpoints (services, projects) for the different tasks - they can still use the same database layer through a shared project, depending on the architecture you have. This would let you have separated services with the appropriate serializers without custom attributes and code (see below). For example, create a separate project for the reporting REST services.
OPTION 2: add some custom decoration on the endpoints so you can choose which serializer is used on each, you can find some examples here: https://stackoverflow.com/questions/59650907/how-to-configure-two-json-serializers-and-select-the-correct-one-based-on-the-ro - the point being to register a serializer depending on the endpoint based on your own code rather than let the framework put one in for all endpoints.
NOTE: This would be a breaking change.

In some cases, when the path of the file is used as a Value of the PictureBox, the WMF is not displayed in PrintPreview or in the printed report. The workaround is to embed the image by selecting the file as a Value:
1. Go to the Value property of the PictureBox and click on the three dots (...)
2. In the File name field, type *.* and Enter.
3. Select the WMF file.
I am using this to color the xaxis, but I notice, it changes the color of all items, so what I want is to color them individually based in a condition like this:
XAxis.Style.Color = IIf(ToolStatus=1,'Green','Red')
The problem all the text is in green not considering the condition individually by column.
The parametersAreaVisible property of the angular report viewer allows controlling the visibility of the report parameters area.
Currently, this property can only be set. Reading the property doesn't reflect the current visibility of the report parameters area.
While jquery can be used as a work around to determine the visibility of the report parameters area (by reading the width of the corresponding DOM element), a proper angular API would be nice.
