The following code represents how to check the editing status of the document.

@using Syncfusion.Blazor.PdfViewer
@using Syncfusion.Blazor.Buttons

<SfButton @onclick="OnClick">Check</SfButton>
<SfPdfViewer @ref="Viewer" 
             DocumentPath="@DocumentPath" 
             Height="640px" 
             Width="100%" 
             ServiceUrl="https://ej2services.syncfusion.com/production/web-services/api/pdfviewer">
</SfPdfViewer>

@code{
    public SfPdfViewer Viewer { get; set; }

    private string DocumentPath { get; set; } = "PDF_Succinctly.pdf";

    //Prints the document's edited status in console window.
    public void OnClick(MouseEventArgs args)
    {
        Console.WriteLine(Viewer.IsDocumentEdited);
    }
}
