@code {
    DxRichEdit richEdit;
    Document documentAPI;
    /* 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. */

            documentAPI = richEdit.DocumentAPI;
            var sections = await documentAPI.Sections.GetAllAsync();
            foreach (Section s in sections)
                await s.ChangePropertiesAsync(properties => {
                    if (s.HeaderOffset != 850)
                        properties.HeaderOffset = 850;
                });

            Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
