Provide CanShrink property to report page sections so they can change their size dynamically depending on their contents. It will be very useful in scenarios where items in the page section are hidden conditionally and page sections needs to resize, allowing the detail section to use the available space.

In the standalone report designer, when I copy and paste a group of adjacent TextBoxes, overlap warning icons appear on some of the pasted items.  I then tried moving the group of pasted items to a new snap-to-grid location, but the icons do not go away.  This can create a good deal of work to clear up the warnings by individually adjusting the affected items.

In the attached report, the three items in the report header are the original TextBoxes without overlap.  The three in the detail section are the cut and paste items showing overlap warnings.    The three in the page footer section are the cut and paste and move items still showing overlap warnings.

After submitting this as a support ticket, I received this message from Telerik: "The development team found an issue in the Copy/Paste logic and updated it. The change will be available in the next internal build for tests."  I was using 2017 R2, version 11.1 17.614.

When selecting report in print preview mode with a windows DP setting of 125% the report is not corrected. This results in report which is shifted on paper when printing is invoked. See attached file. Request a setting which can overrule the operating system DPI setting.

Suppose I have create a chart with fixed y axis (from -4 to 4), Instead of displaying numeric value on the y axis label, i will need to change it to other strings like :
-4 -> -4σ
-3 -> -3σ
-2 -> -2σ
-1 -> σ
0 ->x̄
1 -> σ
2->2σ
3->3σ
4->4σ

It would be nice if it can format the value of each Axis label (particularly for fixed max and min value)

Currently the gridlines are displayed only under the series but in some cases it would be better to be visible over the series. In case the graph displays Area series and then Line series over the Area, the Area hides the gridlines so they can not be used to match the X and Y on the Line series.

please add a  feature to set multiple color palette for graphs series and based on user selection we should be able to  switch them conditionally

HTML content is currently displayed verbatim in Report Viewer Tooltips. Tooltips should work as kendo tooltips usually do, rendering HTML when detected.

freeze certain columns in a table when we scroll right and left in Telerik Report and the same should be applicable when we do export to excel

I write very complex reports with many, many objects. For the past two years using Telerik Reporting (which I love, don't get me wrong), I have been driven mad by the tree jumping to the top when I am working on a section towards the bottom.

Every tree view I have ever worked with has had an EnsureVisible on the selected node of the tree. Could you please find it in your heart to make this change. It takes me 20 times longer to build / modify reports than it has to.

I'm attaching my customer quote report so you can see the complexity I am working with and why scrolling back to where I was EVERY TIME is so maddening.

I've seen some suggestions similar to this, but none that are exactly the same.  I would like to have the ability to select any item within the Report Explorer and drag/drop it to the location that I want it to appear.  Perhaps this isn't possible due the way the Report Explorer works, but this would allow greater flexibility in where a control is located, versus the current Bring To Front/Bring To Back options.

Our client is strongly requesting a "zoom" by graphical selection feature, as available in their former tool qlikview (or amcharts,  for example).
I am surprised this feature has not been requested yet, since any user would greatly benefit from it.
It's an extremely powerful and intuitive way of restricting your selection of report input parameters in a visual manner. 
By drawing a rectangular selection with mouse over the graph, you restrict the range of both x and y axis to the selected ranges, allowing quick zoom to the area of interest
Examples: just draw selection rectangles on a chart in one of the examples below

After upgrading Telerik reporting to 10.2.16.914, I get the following error when trying to generate reports. The App.config hasn't needed any custimizations before. Why is it that every Telerik update always breaks our applications??? 

An error has occurred while processing Report 'OACLJB005':
The assembly "JobBank.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" is not permitted to be used by an ObjectDataSource 
component. Please include it in an AssemblyReferences element in the Telerik.Reporting configuration section of your application configuration file.

I find it extremely limiting and frustrating to not have control over how the .NET Report class is initialized, and not being able to pass in any type of object/dependency (either into the constructor or by setting a property.) This makes it very difficult to keep custom reports decoupled from other code modules and make them unit-testable. 

There is the InstanceReportSource, which would have been perfect to solve this problem, but it's apparently deprecated.
http://docs.telerik.com/reporting/t-telerik-reporting-instancereportsource

DevExpress reports for example allow you to create the report instance yourself, and you can pass any objects you want directly into the constructor. 

This is what I find to be the biggest drawback to Telerik reports. 

just the same like here

Support for Apple Numbers to be able to open reports exported in the "Excel Worksheet" format.

Would it be possible to prioritize which characters can "Break" when wrapping text inside a text box?  For example "foobar/foobar" will not break at the slash, it'll instead break at the character that hits the width limit. It would be my suggestion that punctuation be prioritized for "breaking" before all other characters, in the event that there is no space.

In the attached example, the column headers are dynamic (localized), and there's no way to predict what the text will look like (in whatever language)... Though I accept that no matter what, a string longer than the textbox width will need to break somewhere, I'd prefer that you break on "better" characters if they are present.

(Pretty nitpicky, I know, but this would save me trying to code the logic into an expression or function... which could prove complicated due to variable width of fonts)

We redefining an existing table style (ie. Aspect) in an external style sheet, the user should be able to select the style like now, but disable the style generation in the report file.
Currently, we need to go in the designer.cs file to remove all unwanted styles.
