I wanted to add some white space between the TOC text and the leader symbols in my TOC. Here is the default TOC when I don't use whitespace:

I tried the following Expression:

= Fields.group1 + "            "

Here is the result - the TOC text of the first level was displaced as if the added whitespace is before the text:

The workaround I found is to add one LeaderSymbol at the end of the whitespace string:

= Fields.group1 + "            ."

Still, it seems that there is whitespace trimming that is not correctly implemented for the TOC section.

Hi,

Have the possibility to have the "Select Case" or "Switch" function in the expressions.

Thanks!

The Telerik.Reporting.Report class has the property ExternalStyleSheets which is an ExternalStyleSheetCollection.

This collection consists of objects of the type ExternalStylesheet which has private Name and ResourceKind properties.

Would be great and make sense to make these properties public since that would help when the external stylesheets need to be resolved dynamically, though a custom IReportSourceResolver for example.

We separated our data objects into a library project and then referenced it via the web.config. It works as intended, both in the designer and during data retrieval, but to update the dll with more objects we have to restart the whole site.

It would be very useful if we could substitute our assemblies without restarting the website.

Hi

I need to adjust line spacing in multiple line textbox but currently there seems to be no way to do that. Please add this feature!

Thanks

I want to export a Report as a PNG image with transparent background.

I set the Style > Background to Transparent for the PictureBox in the detail section, for the Page and Detail sections, for the Report itself, and for Report > PageSettings. The PNG image is still rendered with white background.

Hi, While the Report Designer exports tags to the PDF (with Accessibility enabled), the tags exported are not fully compliant with PDF/UA or 508 requirements. For example, my document has several hundred pages, each with two or three data tables on them. While the tags get exported, they are only Paragraph tags, and NOT Table tags. Is there a way to designate Table Header Rows, Header Columns, and Data Cells in Telerik Reporting such that upon export to PDF they get tagged properly?

Currently a single instance of the WPF Report Viewer will often use multiple different HttpClient instances to talk to the Report Server.  This means that cookies added as part of earlier requests may not be sent in later requests.  If the Report Server is behind a load balancer that uses cookies to implement 'sticky sessions', this loose behavior with cookies will cause requests to get routed to different servers which is not ideal.  It is possible to use a storage mechanism on the server that natively supports a web farm (such as the Redis storage option) but that can be tricky to set up.  

Instead, if the report viewer were to re-use the same HttpClient instance for all requests (including initial render request, export requests, print requests, etc.), the load balancer could work to route all requests to the same web server and then any storage mechanism (such as the simple File storage option) would work.

This issue was reported back in 2017 and I'm running into the problem again in 2022.  See: https://www.telerik.com/forums/wpf-reportviewer-cookie-behavior

Due to breaking changes related to the Kendo state classes - https://docs.telerik.com/aspnet-core/styles-and-layout/components-rendering-overview#state-classes, report parameters loaded in the HTML5 Report Viewers that use the ListView widget, are not selected properly, thus the report is not updated with a new report source and the data does not change.

Using the Default or Material Kendo Theme (v5.6.0) with the Telerik HTML5 Report Viewer, the Boolean parameter which uses a Checkbox for it's display, is not visible (this may affect other themes as well).

I confirmed an older version v4.40.0 has a height and width set for the k-checkbox CSS class as such:

https://unpkg.com/@progress/kendo-theme-material@4.40.0/dist/all.css

.k-checkbox {
    border-radius: 2px;
    margin: 0;
    padding: 0;
    width: 16px;
    height: 16px;
    line-height: initial;
    border-width: 2px;
    border-style: solid;
    outline: 0;
    box-sizing: border-box;
    background-position: center;
    background-repeat: no-repeat;
    background-size: contain;
    display: inline-block;
    vertical-align: middle;
    position: relative;
    cursor: pointer;
    -webkit-appearance: none;
}

while the latest v5.6.0 does not:

https://unpkg.com/@progress/kendo-theme-material@5.6.0/dist/all.css

.k-checkbox {
    margin: 0;
    padding: 0;
    line-height: initial;
    border-width: 2px;
    border-style: solid;
    outline: 0;
    background-position: center;
    background-repeat: no-repeat;
    background-size: contain;
    display: inline-block;
    flex: none;
    vertical-align: middle;
    position: relative;
    cursor: pointer;
    -webkit-appearance: none;
}

The checkbox is actually on the page, but is so small it's basically invisible and completely unusable, requiring a manual CSS override to fix.

Boolean parameter checkbox is with a small size in the HTML Viewer with Kendo SASS theme created with ThemeBuilder.

The current workaround is to use the following CSS to set the width and height of the checkbox:

.k-checkbox{
   width: 16px !important;
   height: 16px !important;
}

In the Web Designer, I can create OhlcSeries but I cannot find a way to provide the OHLC marks. Whatever I enter for Y value, in the Design view I see the error "The XML serializer cannot resolve type with name: Telerik.Reporting.OhlcMarks". In Preview the error is "An error has occurred while processing Graph 'graph1':ohlcSeries1: OHLC values value cannot be null or empty when using NumericalScale".
If I created an OHLC chart with the Standalone Designer and opened it in the Web Designer, the Y value would display "[object Object]" as seen in the linked screenshot.

We use Reporting REST Service to generate our reports. When exporting to BMP, EMF, GIF, JPEG, and PNG which are all multi-document formats, the downloaded documents are corrupted and cannot be opened in Image viewer.

The TIFF image, which is a single document is exported and opened as expected.

My report contains emojis, and they are displayed properly in the designer and in the Html5 Viewer.

When I export to PDF, the emojis disappear. The emoji font is listed as embedded in the PDF file. Even if I embed the full font, the emojis are not displayed.

I am using the HTML Report Viewer and have a report with a parameter that renders as a combobox in the parameter panel of the report viewer.  The tab order of the report parameters do not follow the display order of the parameter fields, specifically any parameter fields that use comboboxes.

An example of this behavior is in the "Employee Sales" report on the Telerik Reporting demo site (https://demos.telerik.com/reporting/employee-sales).  In the report there are 2 parameters, one for Report Date (using a date picker control) and another for Employee (which uses a combobox).  The report viewer is configured to use the combobox option for viewing single and multi selects:

    parameters: {
        editors: {
            singleSelect: telerikReportViewer.ParameterEditorTypes.COMBO_BOX,
            multiSelect: telerikReportViewer.ParameterEditorTypes.COMBO_BOX
        }
    }

When rendered, the Report Date input has a tab index of 301 whereas the Employee combobox has a tabindex of 0.  This results in the tab order of the parameter inputs to not follow the order in which they appear. 
        
I have found that if the above settings are commented out, the tab order of the parameter fields works as expected, but results in a list view control instead of a combobox which is not desirable.

Is it possible to override the tabindex of a combobox parameter input to be set to a tabindex value that is relative to its siblings (i.e., 302) so that tabbing through the fields via keyboard is more natural?

We can use Telerik UI components with gRPC service however, Telerik reporting service and HTML 5 viewer do not support gRPC.

With gRPC use growing among the developers, we would like to see Telerik reporting support gRPC out of the box.
