The report has a single-value nullable parameter with AvailableValues.
When you preview the report in the Standalone Designer, if you checked Null, the value would be respected.
When you preview the report in Html5 Viewer and the parameter value selection is cleared, instead of rendering the report with a Null value, the report is rendered with the last selected value.

Steps to produce in the Html5 Viewer:

1. Select a value from the filter
2. Click the "Preview" button
3. Report generated based on the selected value
4. Click the "clear selection" button and it clears the selected value from the filter
5. Click the "Preview" button
6. Report is generated based on the value selected before it was cleared rather than with Null value

Here is a link to a muted video on how the issue may be reproduced.

If the parameter is not Nullable, the Preview button after step 4 stays enabled, and clicking on it produces the same result as with the Nullable parameter.

In a cascading dropdown, we noticed that the child dropdown is not populated until the parent dropdown is closed after selection. There is a second delay between selecting the parent dropdown and populating the child dropdown. Between this small interval of time, the preview button can be clicked, as it is not disabled, due to which wrong values (previously selected values) are passed in the parameters resulting in incorrect results.

I have cascading parameters, and in some cases, the data set for the dependent parameters is empty. In these cases, the parameter editor of the second parameter is displayed as an input/textbox rather than a dropbox without data.
In the Standalone Designer, the parameter editor is displayed as expected, with a dropdown without data.

The report for reproducing the issue is Product Line Sales-01.zip

In the PDF rendering engine, clipping SVGs is not supported out-of-the-box. Instead, the whole SVG content is rendered without applying any clipping which can lead to differences between previewing the report in the report designer and when exported to PDF. For example:

In design

In the report preview.

In the PDF file.

The following warning is shown in the browser console when starting my Blazor application when I use the native Blazor Report Viewer:

WARNING: Processing source-maps of https://localhost:7025/_content/Telerik.ReportViewer.BlazorNative/js/reporting-blazor-viewer.js took longer than 11000 ms so we continued execution without waiting for all the breakpoints for the script to be set.Could not read source map for https://localhost:7025/_content/Telerik.ReportViewer.BlazorNative/js/reporting-blazor-viewer.js: Unexpected 404 response from https://localhost:7025/_content/Telerik.ReportViewer.BlazorNative/js/reporting-blazor-viewer.js.map: 

In Web Report Designer HtmlTextBox input is just simple TextArea. There is a great need to be able to enter rich text as in a desktop application.

Could you add a property to the TelerikReportViewer so the user can pass queryStringParams to server api calls. For my case, I need it to support multi-tenant. 

Thanks

After updating the Telerik Reporting packages to v17.2.23.1010 and opting out to still use the Gdi graphics engine, when I attempt to render a report to PDF on Linux, the rendering fails with the following error:

In the Desktop Report Designers, you may display the Text of the Tooltips on several lines by adding new lines (\n) inside the text.

In the HTML5 Viewrs, the new lines are ignored and the text is displayed on a single line. You may work around this by replacing the new lines with <br /> elements. It would be much easier for the users if this is done in the code of the viewer instead.

We upgrade to 17.2.23.1010 and after going through the report Upgrade Wizard we are getting this error for the CheckBox item:

Error CS0266 Cannot implicitly convert type 'System.Drawing.ContentAlignment' to 'Telerik.Drawing.ContentAlignment'. An explicit conversion exists (are you missing a cast?)

Conditional formatting property already exists in Telerik.Reporting.LegendItem class however does not exist on Telerik.Reporting.GraphLegend.

Would be great to have a ConditionalFormatting property into the Telerik.Reporting.GraphLegend to allows to perform bindings on this element.

Exemple of use case not possible currently: Bind the GraphLegend.Position property with an expression.

When my application runs in full trust permissions set, the following error is thrown if I have used the Telerik.Reporting.OpenXmlRendering NuGet package and try exporting to any of the OpenXML formats :

ERROR: Attempt by security transparent method 'Telerik.Reporting.OpenXmlRendering.Spreadsheet.Workbook..ctor()' to access security critical method 'DocumentFormat.OpenXml.Packaging.SpreadsheetDocument.Create(System.IO.Stream, DocumentFormat.OpenXml.SpreadsheetDocumentType)' failed.

HTML5 Report Viewer installation resources contain an old version of the Kendo blueopal theme - C:\Program Files (x86)\Progress\Telerik Reporting 2024 Q1\Html5\ReportViewer\styles.

Please update the kendo stylesheets to the Kendo version the report viewer currently uses.
