Utilizing Native Blazor Report Viewer with Telerik Blazor UI 4.0 results in some toolbar icons appearing blank. The icons are still functional.

Switching to Blazor UI 3.7 fixes the issue.

Here is a snippet from the file '/@progress/telerik-angular-report-viewer/dist/es/telerik-report-viewer.component.js' in Telerik Reporting NPM repository of the Angular Viewer that hard-codes the message:

TelerikReportViewerComponent.decorators = [
        { type: Component, args: [{
                    selector: 'tr-viewer',
                    template: '<div [ngStyle]="containerStyle" [attr.id]="reportViewerID" #container>Loading Report Viewer...</div>',
                    styleUrls: [],
                    encapsulation: ViewEncapsulation.None,
                },] },
    ];

Currently, there is no easy way for localizing or removing this message in an Angular-wise approach.

The DocumentMapVisible/ParametersAreaVisible settings that I set in the initialization of the native Blazor Report Viewer are not respected.

I can hide/show these areas from the buttons in the report viewer's toolbar but am unable to have them hidden initially.

Currently, the only workaround is to have a JS function that clicks on the toolbar after initialization:

function reportViewerMapClick() {
    $(".k-i-dictionary-add").click();
}

In this file t.folder is lowercase which should be Capital t.Folder

t.folder  throws error

 t.Folder return value

same or files vs Files

Currently, I am using XmlSerializer to deserialize .trdx file, and it returns Telerik.Reporting.Report type object.

Since, for a long time, I need to add my own functions to be available in the report's expressions, and this need becomes larger and larger, it would be great if I could use the Telerik.Reporting.XmlSerialization.ReportXmlSerializer class to deserialize the .trdx file in my derived class.

For example:

var report = new Telerik.Reporting.XmlSerialization.ReportXmlSerializer().Deserialize<MyReportDerivedClass>(TemplateStream);

I am trying to add HtmlTextBox to my report. After double-clicking on the HtmlTextBox, instead of opening the HTML editor, an error message appears 

And after that, it is not possible to delete any element of the report

When the EnableAccessibility PDF device info setting is set to true in the RuntimeSettings of a report, the text set to an item in the AccessibleDescription report item property is not respected.

For example, a PictureBox with AccessibleDescription set to "Text1" will have the "Picture Box" alternate text set in the exported PDF instead of "the Text1" string.

Recursive sub-report with hierarchical data. When expanding/collapsing, all nodes get expanded or collapsed.

I would expect only the selected node to be expanded/collapsed.

For reference, the report from the How to represent hierarchical nested data in report recursively - Telerik Reporting KB article was used as a base 

Using a Toggle Visibility action to expand/collapse recursive SubReport results in the "Node should be found among parent nodes" error. The recursive SubReport renders fine without the action.

The report from the How to represent hierarchical flat data in report recursively - Telerik Reporting KB article was used as a base.

The source of my SubReport was in a nested class and in the preview of the main report I received the error "Invalid report type" although the same nested class was successfully discovered in the VS designer with the assembly-qualified name 'Test.Class1+DetailReport1, Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

When I tried using a class (without a nested class, e.g., 'Test.DetailReport1, Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null') then I could get the subreport to render within the main report.

It could be the syntax for the qualified name is not handling nested classes. 

Attempting to delete a group section from the Explorer tab in the Web Report Designer leads to the following error being thrown in the browser console:

Uncaught (in promise) Error: Rollback inner transaction
    RollbackTransaction http://localhost:51863/api/reportdesigner/designerresources/js/webReportDesigner-16.2.22.1109.min.js/:9
    Rollback http://localhost:51863/api/reportdesigner/designerresources/js/webReportDesigner-16.2.22.1109.min.js/:9
    execute http://localhost:51863/api/reportdesigner/designerresources/js/webReportDesigner-16.2.22.1109.min.js/:9

As a result, the section is not deleted. However, the section can be deleted by deleting the corresponding report group from the Properties area(Data section) in the Web Report Designer.

In such a case, the following exception is thrown

Inner exception: System.ArgumentException: The path is not of a legal form.
   at System.IO.Path.NormalizePath(String path, Boolean fullCheck, Int32 maxPathLength, Boolean expandShortPaths)
   at System.IO.Path.InternalGetDirectoryName(String path)
   at Telerik.Reporting.Interfaces.FrameworkDependentDeploymentModel.GetDirectory(Assembly assembly) in

The likely reason for the error is that since the assembly is loaded from the bytes, and not from a path, the assembly.Location in the Telerik.Reporting.Interfaces.FrameworkDependentDeploymentModel.GetDirectory method is Null.

In some scenarios, the PrintOnLastPage functionality of the page sections does not work as expected.

For example, if the report with PrintOnLastPage is the last one in the report book, on the last page of the report book, which will also be the last page for that report, a page section will still be rendered even if PrintOnLastPage is False.

This happens when the default PageNumberingStyle.Continue is used by the reports.

On the other hand, if the last report has a PageNumberingStyle.ResetNumberingAndCount, the page section will not be rendered if PrintOnLastPage is set to False, so in this scenario, it works as expected.

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.

When a report has a report parameter using a data source, that is visible and has AllowNull set to True, if the value initial value is invalid, no report parameter widget is loaded at all for this parameter.

If this is the only report parameter, the parameters area is not rendered at all, even though the toolbar indicates that it is active.

The issue can be reproduced by loading the attached report in the native Blazor Report Viewer.
