Remarks
Call the LoadDocumentAsync method to load a document from a file.
The DocumentLoaded event occurs after the Rich Text Editor loads a document. Handle this event to change the content of a loaded document.
The example below loads a document from a file:
<InputFile OnChange="OnChange" />
<DxRichEdit @ref="richEdit" />
@code {
DxRichEdit richEdit { get; set; }
private async Task OnChange(InputFileChangeEventArgs e) {
/* 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 cancelled. */
try {
IBrowserFile file = e.File;
await richEdit.LoadDocumentAsync(file);
}
catch (OperationCanceledException e) {
Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
}
}
}
