It would be nice to catch the parameters of the HTML5 viewer and the report engine.
I need to encrypt the parameter Ids that is visible to any man-in-the-middle attacks.

I did encrypt the parameters, and tried to use "CustomReportResolver : IReportResolver" to catch and decrypt it before send to the report engine or the report data source. But the resolver has only the report Id or name.

I'm using UriReportSource because we need to evaluate and try dynamic reports.

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

As a reports author I need ranking functions ( https://docs.microsoft.com/en-us/sql/t-sql/functions/ranking-functions-transact-sql ) so that I can use them in specific scenarios.

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).

Right now, if I want a textbox to always take up space, even if visibility is set to false, I need to wrap it in a panel. I would love to be able to just check a boolean and have this done behind the scenes. Having everything wrapped in panels makes things a pain to rearrange and needlessly complex. 

Barring that, at the minimum, having a function to "wrap" a textbox with a panel would be nice so I don't have to create one, move the textbox, make the panel match the dimensions of the textbox, drop the textbox in, and then move the panel back where the textbox was.

A report viewer feature for SSRS (RDL) so that we can utilize the SSRS 2016 HTML5 in our apps

Currently the images loaded in PictureBox item and Style's BackgroundImage property are rendered preserving the item's physical size. This causes scaling when the machine's DPI is different than the image DPI and affects the image quality.
A specific option should allow the images to be rendered without being altered, including applying antialiasing on the target graphics object.

Add support for reusable items. Create a report item like Panel, Table or Graph and then export and share to other reports. If a reusable item is modified a change can be propagated to all reports that use this reusable item.

It would be nice to have an option on the report book to Collate and set a Multi-Value Parameter or Data field as the list for collation. Essentially if i have 3 reports (A, B & C) and they have parameters of Start Date, End Date and Client(Multi-Value) and i want to collate by selected clients. The report book should then render the report as follows

Report A - Client 1
Report B - Client 1
Report C - Client 1
...
Report A - Client 2
Report B - Client 2
Report C - Client 2
...
Report A - Client 3
Report B - Client 3
Report C - Client 3

Collation is a very common scenario when working with multiple reports

The report processor renders a report to XLSX format and adds a BOM (EF BB BF) to every embedded XML file. This is causing some open source libraries to fail to load the XLSX file, which is an issue for some of our customers.

var deviceInfo = new System.Collections.Hashtable();
var reportProcessor = new Telerik.Reporting.Processing.ReportProcessor();
var result = reportProcessor.RenderReport("XLSX", instanceReportSource, deviceInfo);

The work-around is to load the XLSX file in Excel (which apparently ignores the BOM) and then save it (which removes the BOM).

I have read that the BOM is optional (and undesirable for compatibility) for UTF-8 encoded files, which is how the report processor renders XLSX.

Please remove the BOM, or add a Device Info setting "WriteBOM = true/false", similar to the CSV export device info.

Thanks, much appreciated!

As a reports user I would like more options for Line Styles in Chart plots.
Currently the options are Solid, Dashed and Dotted.
As a start it would be great to replicate the options in the Kendo UI Line Charts dashStyle enumeration:
https://docs.telerik.com/kendo-ui/controls/charts/chart-types/line-charts#configuration-Types

As the perfect option list for me:
Solid
ShortDash
ShortDot
ShortDashDot
ShortDashDotDot
Dot
Dash
LongDash
DashDot
LongDashDot
LongDashDotDot

Thanks

There is no way to fix a panel or report section so that I can print a fixed height report, internal controls of panel should grow vertically but panel it self should not grow.

Hello,

today I inserted many textboxes and fields from data source and draw my own table. Problem is, if more than one field is near one positon i cant position the field exactly.

If i marked more than one object i can't set x or y position per input. My idea is, mark all objects, open the position option and set for example from left 1cm, hight from the objects stays the same

Thanks!

I have a report with a column that repeats values and would like to suppress the repeats.  In other report writers I have worked with (SSRS, Crystal, ...) it is a right click and you select suppress duplicate values from a checkbox.  The result is that duplicates on the same page are hidden, and when a new page begins the first row will show the value and then it is hidden for subsequent rows.  (See attachment)

I am optimistic that this functionality exists and I am simply not looking in the right place.

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

Let us know if collapsing report sections in report designer would make the designing of reports more convenient for you.

When reports have more complex structure with a lot of sections collapsing some of them might improve the overall design time experience.

A common scenario is to specify the printer name when printing a report.

Currently, this can only be achieved with manual printing where you can pass the PrinterSettings object(https://msdn.microsoft.com/en-us/library/system.drawing.printing.printersettings(v=vs.110).aspx) with specified PrinterName as a parameter to ReportProcessor.PrintReport method.

Let us know if you think exposing the PrinterSettings object (for example as the setting of the viewer) would benefit when working with reports. Please share your thoughts and ideas on this topic in the comments.

Thank you.

Using a report book with individual page numbering for each reports and a separate page numbering for all pages in the whole book. Example in attachments.

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

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