    <DxRichEdit @ref="richEdit" />
    
    @code {
        DxRichEdit richEdit;
        protected override async Task OnAfterRenderAsync(bool firstRender) {

            await base.OnAfterRenderAsync(firstRender);
        }
    
        async Task InitializeDocument() {
        /* 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 columnCount = 4;
