NuGet Package: DevExpress.Blazor.RichEdit
Declaration
[Parameter]
public byte[] DocumentContent { get; set; }
Property Value
Type | Description |
---|---|
Byte[] | Document content as an array of bytes. |
Remarks
The DocumentFormat property specifies the format in which the DocumentContent
property stores an open document’s content. Change the DocumentFormat property value before you open a file in an another format.
The Rich Text Editor updates the DocumentContent
property value in the following cases:
A user selects the File → Save ribbon command.
A user presses Ctrl+S.
You call the SaveDocumentAsync(CancellationToken) method.
An auto-save timeout expires.
The DocumentLoaded event fires when you use the DocumentContent
property to open a document. Handle this event to change the content of an open document.
The DocumentContentChanged and DocumentContentChanging events occur every time the DocumentContent
property value changes. The following code example handles the DocumentContentChanged event to save changes made to a document:
<DxRichEdit DocumentFormat="DocumentFormat.Rtf" DocumentContent="@documentContent"
DocumentContentChanged="OnDocumentContentChanged" />
@code {
byte[] documentContent;
async Task OnDocumentContentChanged(byte[] content) {
/* 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 {
documentContent = content;
await File.WriteAllBytesAsync("C:\\Users\\Public\\annual-report.rtf", documentContent);
}
catch (OperationCanceledException e) {
Console.WriteLine($"{nameof(OperationCanceledException)} thrown with message: {e.Message}");
}
}
}
