I use telerik reporting R2 graph.I can't styling for categroup grouping have child groups.I think it would have styling for this.thanks.

As opposed to having to iterate through every entity in a report using send to front/back, how about just creating the PDF in the order in which the entities exist on the report? Ignore the order in which the entities were created - export them in the order they appear

There should be a way to handle the click of Export button. If someone wants to export to PDF with some changes in the report (change in color etc.) there should be a way to handle the Export event and a handle to change some report parameters being exported.

Multi-value parameters are not formally supported in Telerik Reports that are based upon a Stored Procedure datasource. To circumvent this, I currently use a workaround as detailed in a post by me in the reporting forum here:

http://www.telerik.com/forums/how-to-pass-multi-value-parameters-to-a-stored-procedure-datasource

One of your admins, Nasko, suggested Telerik may look into implementing this procedure out-of-the-box to streamline it for users, hence I am posting this suggestion here to track it.

For an out-of-the-box implementation, it would be nice to see the possibility of setting a parameter datatype to "List" or something similar to denote it will send a serialized string to a Stored Procedure datasource and do the Join() of the selected multi-value parameter items automatically. It will still depend upon having a table-based function in the target database to de-serialize it though, I suspect.

When printing the Online Documentation from Internet Explorer, only the first page is printed. The only way to print it, is to copy the page to Word and then print it.
Please add a method of printing a topic.

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

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)

DOCX document format supports font embedding like PDF does. But currently only the PDF font embedding is implemented in Reporting. This, together with recent implemented PrivateFonts feature, will give us an option to use one more document format without the need to install custom fonts on the client's machine.

Add "Rows to repeat at top" feature to RadSheetProcessing. This is found in the Page Layout Settings in Excel and takes  range. 

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.

Hi Team,

While exporting the report displayed in the web report viewer to CSV, we are exporting the textbox name as header value. Which leads to a problem while exporting a dynamic value whose control name is decided at run time. Please provide an option to assign and export value assigned at runtime.

Details of the issue are discussed in below link. Please have a look over the comment raised on 25th Sept 2014 by Perry.

Thanks

We use ReportProcessor.RenderReport to create each report in code.  When done, we need to know the number of pages in the report.

Add an event to ReportBook to fire when a Report is loaded and when a Report is Disposed.

On the design surface, there is no indication of the z-order of the sibling items nor an easy visual way to change it. Please improve this.

In some scenarios it might be useful to alter the compression of the responses returned by Reporting REST service.

When using Table item with dynamic columns (Visible property on column "binded" to expression) it would be nice to have the "ColumnWidth" also bindable in order to make some columns wider to fill the horizontal space if columns have been hidden

Add Telerik Windows Form Report Viewer configuration option to use Image rendering based on a Bitmap instead of a Metafile. This will enable the hosting of Telerik Reporting REST Service in Azure AppServices for Windows Forms Report Viewer usage.

When printing large runs of multi page documents (production work orders where each job is 5 pages and we are printing 100 jobs), to support stapling options on the printers.
All office products support this and PDF programs.

Currently, we can control if the PageHeader section should be rendered as an Excel native page header or as regular rows. The latter option always makes these rows frozen in the Excel sheet. It would be good to have this customizable (frozen/not frozen).

add the possibility of show the parameters area on right/left/below of report viewer.
