There seems to be an issue with the filter / parameters with comma separated values for Multivalue. I've tried numerous ways to get this to work directly in the preview function on the report designer. Nothing done so far works.
Set Filter to multi
Set Parameter to IN 
Typed in value, value - typed in 'value','value', etc. This is a basic text field so I am not certain as to what exactly should be put in the filter box to allow for 2 or more values in a filter.
This produces data on the report with IN and Multivalue 
This produces an error
The current data set presented in the report did not produce any significant content, so no pages were generated. If you need to see the whole report content, including blank pages, please contact the report author.
Please advise exactly how to do this with an example. I have scoured the forums and the documentation with no relevant information that works for a multiple value field.
Thanks in advance.

Hi,
I request you to add a new property in the report object when we unpackage the TRDP file to get a list of fields that are used in the report template.
Currently, We are not able to identify how much data we need to extract from the database as we are using the ObjectDataSource component in the report we have the number of fields in the data source but fewer were used in the report template hence on the performance point of view we need to get data only for those fields.
Thanks.
When building report templates in the Standalone Report Designer, it would be very helpful to have a keyboard shortcut to access the Property Browser and possibly the other panels (Report Explorer, Data Explorer, Group Explorer).
I have grown accustomed to the shortcuts available in Visual Studio for similar access. For instance, the F4 key will jump to the Visual Studio Properties panel (at least in my configuration) from a designer window. This makes it easy to update things like field name, size, location, and other properties without constantly reaching for the mouse.
Visual Studio uses Control-R to access its Project Explorer (again, in my C#-centric configuration), perhaps similar to the Report Designer's Report Explorer.
Adding these keyboard shortcuts, whether fixed to specific keys or configurable, would speed up report development for keyboard-bound programmers like me.
An error has occurred.

If you drag and drop a List in a Report in the Web Report Designer, and then reduce its height and the height of its inner Panel from the Property editor, initially, the changes are respected. When you save the changes and reopen the same report, the Panel recovers its previous Height.
The issue is not reproducible when modifying List or Panel size with mouse dragging.
I have a request that probably doesn't require much explanation. It would be helpful to allow comments in expressions created via the standalone designer to help explain particularly complex and infrequently encountered logic.
As for now, the workaround is to use the series' DataPointStyle.BackgroundImage property to add a custom image as a marker. Then, to change this image based on the condition you can use DataPointConditionalFormatting property.
The Marker Types I am using are commonly used e.g Square, Plus, Cross. Please add an option to set Marker Type for the values instead of background Image.
There is nothing really pro outside visual controls for reactJs to many source to many projects could be amazing if telerik create this full set including the report viewer
Our team is in the process of converting Crystal Reports documents over to Telerik Reporting and one of Crystal Reports advantages over Telerik Reporting was the ability to create custom fields with Crystal or Visual Basic Syntax, including the declaration of variables. Lack of variables and a few common constructs can make simple expressions overly complex.
One of the more common use cases for us is formatting text differently based on one or more other values. Without the ability to write if/elseif/else blocks we wind up with nested ternary statements which can be are hard to read and maintain.
While we can write user functions that seems impractical for long term maintenance and support. It would be very helpful if we could create expressions using C# directly in the Report Designer and have the embedded within the report itself.
See my initial request for something similar in the forms here: https://www.telerik.com/forums/feature-request-if-elseif-else-and-or-switch-statement-support-in-expressions
