When configuring a datasource through the wizard, the 'Select Statement' TextBox should standard support keyboard shortcut ctr+A to selelct all. Having to open the context menu is a bit awkward.

When selecting several items, it should be possible to change the size and location of all of them, at least if the values are the same

Currently, the size and location of items displayed in Properties view are rounded value, but the real value written in the .Designer.cs isn't rounded at all.

This created some imprecision in size and location, possibly resulting in unwanted resizing of the report width, or in overlap.
Now, it is only possible to correct this in .Designer.cs, and the user don't see the problem without zooming at maximum or opening the .Designer.cs

Rounded value seems better than some unneeded decimal, but then the value displayed should also be written in the .Designer.cs

Can the Telerik Reporting libraries be available for install as a NuGet package that can be hosted on a local NuGet server?

Hosting on the public NuGet server would be even better, but I would imagine that would be harder to get approved.

The interactive view is excellent for providing a full list of rows in a table but sadly it’s not easy to break that result into manageable pages.  If, for example, we have a large table list that isn’t readily breakable into sections, the resultant large table will cause most web browsers to consume a large amount of RAM and suffer performance loss.  It would seem sensible to have the ability to force a page break when the interactive page reaches a certain size.  This way it would reduce the amount downloaded into sensible page sizes and ensure the browser is not overwhelmed.  This would be very similar, I hope, to that already provided by the print preview mode which breaks on the print page size, all we need is that functionality for interactive pages but via a separate ‘Interactive Page Size’ property.

Having a white background in a view when using the dark theme is very bad for the eyes.
You should check all your UI in Visual Studio, as I already asked in the past for a correct context menu for dark theme (now done).

DocumentMap is using the order of report structure to create the tree. For the moment, the only way to change this order is using "Bring To Front/Send To Back" in report designer, which is badly named in this case, and awkward to use.

You should:
-add Bring Forward/Bring Backward functions
-document in DocumentMap help section that theses functions will also change the order in the report structure.

Ideally, a move up/down in report explorer view would be even better (and more intuitive).

Create your own parameter syntex, and translate it to the database specific one according to the provider name.
For example, MsSql uses "@" character while Oracle uses ":" to identify parameters.
We need to be able to execute the same report against multi database types.

When you have your .trdx and external stylesheet files in a separate directory (e. g. a server directory available to all workplaces) it gets very difficult to show the .trdx files in ReportViewer without manipulating the reports a lot by code.

1. The external stylesheets are searched in the bin\Debug directory of the main application when using Kind="Relative".
2. What is even more annoying is the fact that all SUBREPORTS are also searched in the bin\Debug of the main application. I have to recursively look through all report items if there is a subreport and set its location.

It would be very nice if the ReportViewer supports some kind of "path-to-reports" property and locate all the dependend files like subreport or stylesheet in this directory.

Add the ability in the WPF Viewer to consume reports from the rest service instead of from the local computer.  The html5 viewer has this ability and it would be nice to have the full viewer within my application to do the same.  All of my data access is through rest and I want my reports to work the same way.  

We had a pie chart with 9 slices with limited plotting space. The labels are overlapping and random at best and not presentable at the moment. 

We tried the following scenerios:
  ThisPieChart.IntelligentLabelsEnabled = true;
  ThisPieChart.AutoLayout = true;
  Alternate the bigger slice with smaller slice to give good space for labels.
  Printing out in Black and White paper also is a mess as patters are not there on the slices.

At present one cannot have a subreport in report header/footer. This is such a limitation 
e.g. you have a company header which you want in every report. Normally what you expect is to make a subreport and include that in header of other reports. So if you change any details you can edit that subreport and it get reflected in all other reports. But unfortunately you have to include the company header in every report not only the controls but also in the datasource.
I used to develop in MS Access back in 90s and even then its reporting has this feature as standard.
So come on Telerik 

Please consider adding a standard HTML5 viewer template that does not rely on things like Font-Awesome which is neither standard, nor adheres to any sort of disability compliancy (note: Font-Awesome Icons can not be read by screen readers, for the visually impaired). A better option would be to use Scalar Vector Graphics for the icons. It makes little sense to offer a single, non-standard, HTML5 template, out of the box... which forces the end developers to standardize it before it can even be used.

I have encountered this problem numerous times but I will list one of them.  When printing a weekly schedule in the format of a calendar, the days of the week print top to bottom when the desired layout should be L to R.  

We have resorted to various hacks to get this to work, but this is another feature of ***(which we are converting from) that is not supported in Telerik Reporting.

It would be nice if there was an OPTION to flow L to R as opposed to Top to Bottom.

The documentation is syntax prone to errors and does not follow well for new developers. The example code shown usually shows one step, please elaborate and show examples in depth for each topic. I have noticed in the forums that people have been complaining about errors in the documentation for more that two years and its still not fixed. I also see a lot of references to code that is shown in documentation that is obsolete or not yet implemented. The video series posted in the last few months (Q1 2015) are videos from 2009. Why?

When groupings in a cross tab or merged row table span multiple pages the actual row label should be carried over to new page along with a label of some sort (if desired) to mark group is being continued from previous page.

This should also be supported in the standalone designer. 
There is currently a workaround via external assembly but this is not very elegant.

Hello,
RadPdfProcessing supports PDF/A 1-3 since Q1/2015. It would be nice if the Report engine would also support PDF/A exports.
PDF/A will bevome the future european standard for invoicing (ZUGFeRD) and is the current  standard for long time archival of digital documents.

Regards,
Chris

I would like to see a control as in an addition to the kendo mvc toolkit where you could build into an application the ability for customers to design the layouts of their reports.  For example.. Say you have an app you built for multiple customers.  Now the app might have a series of basic report templates in terms of queriable object model outputs. Being able to build an interface that would allow the customers to design their own layouts for what fields, positioning on the page etc..labels etc. and save that design to their account for future consumption would be a huge selling feature for an application. 
Specific example an invoicing application.  Well you could pre build a bunch of templates and have the customer choose one (the only real option currently available)...or you could provide a list of fields(based on object models for the underlying report query) and have an embedded designer allow them to design their own invoice and save it.  

To be able to change the branding from Telerik to our own company or product specific banding. For instance MyApp Report Server with own images.
