The example below loads an Office Open XML document from a file stream:

<DxRichEdit @ref="@richEdit" />

@code {
    DxRichEdit richEdit { get; set; }
    @* ... *@
    /* Surround the code that contains an asynchronous operation with a try-catch block to handle
    the OperationCanceledException. This exception is thrown when an asynchronous operation is canceled. */
        try {
        @* ... *@
            var xmlFileStream = new FileStream("C:\\Users\\Public\\annual-report.docx", FileMode.Open);
            await richEdit.LoadDocumentAsync(xmlFileStream, DocumentFormat.OpenXml);
            @* ... *@
        }
        catch (OperationCanceledException e) {
            Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
        }
}
