Hi all,

The issue with the non-executing NavigateToURL actions in WinUI and WPF viewers is fixed and will be included in the 2022 R2 release, which is due today. The core of the problem was the changed default value of the UseShellExecute property in .NET Core apps. In .NET Framework the default value was true, but in .NET Core the default value is false, which effectively prevents finding the application that will open the provided URL (the default browser on the machine).

As for the second question, if you need additional flexibility on processing the executed actions, you can use the report viewer events, as explained in the How to add interactivity to a report using action event handlers in WPF Report Viewer article. The WPF and WinUI report viewers share lot of common code so the described approach can be used in WinUI apps as well. Here's a sample code that shows how to handle the NavigateToUrlAction and execute some custom code instead of navigating to the target location:

        public MainWindow()
        {
            this.InitializeComponent();
            this.Title = "Telerik Reporting WinUI .NET 5 Demo";

            this.reportViewer.InteractiveActionExecuting += (s, e) =>
            {
                if (e.Action is Telerik.Reporting.Processing.NavigateToUrlAction)
                {
                    e.Cancel = true;
                    System.Diagnostics.Debug.WriteLine($"Action on item {e.Action.ReportItemName} was canceled.");
                }
            };
        }

As for the issue 3: The <a> links in the HTMLTextBox item are not rendered as actions by design. As mentioned in the corresponding HTMLTextBox article: 

The HyperLink (<a> tag) is interactive (acts as an actual hyperlink) only under an HTML rendering extension. To add links in PDF, XLSX, DOCX, PPTX files and HTML, XAML, IMAGE renderings for the different Report Viewers, you can use a Hyperlink Action.

I hope the provided information will help you to resolve your problems. If you need further assistance, please do not hesitate to open a support ticket and we'll do our best to help.
