in the new/current Version "16.2.22.914", when dragging an DataSource-Field on the Report, the resolved expression is wrong.

In the previous Version "16.2.22.622", this worked as expected, see Screenshot.

The attached report demonstrates the issue.

Hello

I have a problem with report generating. We use HTML5 report viewer and basic implementation of ReportsControllerBase on server.
I've noticed that we have the CPU/memory recourse consumption after immediately pressing Stop Rendering button. The time of consumption recourses is the same as time without cancelling(about 18-20 second in my example)
There is log with calls of report generating. Last one with cancelling, previous without. 
(see
*** ReportProcessor.ProcessReport DONE in 00:00:16.1918150 ***
and
*** ReportProcessor.ProcessReport DONE in 00:00:16.8522950 ***)

I've investigated how cancelation is working.
The Stop Rendering button send DELETE request to ReportsControllerBase.DeleteReport endpoint. It does something and set IsDeleted flag for document.
Then DocumentCancellationController.ThrowIfCancellationRequested() is called in some specific places in app. You can see that method in log.txt, so it was called after pushing the button.

I've profiled the hot path of generation of report. See hotpath.png.
The most CPU intensive work happens in ReportProcessor.ProcessRepourtSource()...
Pay attention to rendering calls.png - the first red dot here - ReportProcessor.ProcessRepourtSource() call.
The second - where the exception and actual cancelation happens.
I'm expecting it should happen much earlier and cancellation of generation of document(and resources consumption) will finish ASAP.

By the way, I see some cancelation checks in ReportProcessor.ProcessRepourtSource() as well - see throwIfCancellation.png
But cancelation request came after these check and most intensive CPU works already started.


Is it possible to fix that?

I have a multipage report and my Html5 Viewer is set up in an ASP.NET Core application in .NET 5. The viewer's settings are:

viewMode: "PRINT_PREVIEW",
scaleMode: "FIT_PAGE_WIDTH",
pageMode: "CONTINUOUS_SCROLL",

The problem is that I cannot scroll down to the end of the report.

The issue may not occur in other frameworks with the same report.

The issue may be observed with the online demos - see the linked screenshot.

If I go back and add new records, the total rows count gets updated but still doesn't count the initial rows.

When a TRDP/TRDX report is imported to a CS report, the produced .designer.cs does not have Unicode encoding, instead, it is with ANSI encoding.

Because of this, some of the report text might instead be displayed as ????

The workaround is to Save As the file, from Visual Studio, with Encoding which will open a window where you may change the encoding to Unicode.

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.

Steps to reproduce the problem:

Some corner case page size value force report processing to create an invalid page clipping during paging. 

Workaround: If you encounter such scenario, please experiment with changing the page size to another value, which is close to the original one.

is recognized by the Reporting engine as SVG, which results in the following error in the PictureBox:

An exception has occurred while processing 'pictureBox1' item:

Ideally, if the user prints a report, the output should be the same as what they see on the screen.

Currently, if the user prints/exports the report sometime after previewing it, the data will be updated and they will not get what they see.

If I put the following content in an HtmlTextBox, when I open the preview mode of the designer or look at it in the Html5 Report Viewer I get annoying extra gaps:

<p>Comment</p><p>Comment</p><ol><li>List</li><li>List</li><li>List</li></ol><p><br></p><p>Comment</p><p>Comment</p>

I tried to replace these <p>-tags with <div>-tags:

<div>Comment</div><div>Comment</div><ol><li>List</li><li>List</li><li>List</li></ol><div><br></div><div>Comment</div><div>Comment</div>

It helps. But there are some other tags that cannot be replaced (tags of ordered and unordered lists for example). And these gaps are still rendered. 

Clicking the cancel button on the HTML5 report viewer show "Report processing was canceled" in the UI but the report is still being generated and rendered on the server.

In this old thread it is stated that it isn't possible to cancel the report generation on the server. Is that still the case?

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?

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.

Currently,  you can select multiple report items with the CTRL when you run the Web Report Designer on Mac, however, this is interpreted as a right-click. Please, check the attached video.

The correct behavior should be by using CMD.

I display the WPF Report Viewer control in a closable tab. To free the resources I invoke DisposeViewerResources on tab close as described here: https://docs.telerik.com/reporting/embedding-reports/display-reports-in-applications/wpf-application/disposing-the-report-viewer-resources

However, I see the following dialog every time. There is no way to capture this error or suppress the dialog.
