If the document property is not specified, the control creates and loads a new document.

events Property

Provides access to a list of client-side events specific to the RichEdit control.

Declaration

events: EventHandlers

Property Value

Type	Description
EventHandlers	An object that allows you to assign handlers to the client-side events.

exportUrl Property

Specifies the path where the exported document is sent for saving.

Declaration

exportUrl?: string

Property Value

Type	Description
string	The URL.

Remarks

When a user clicks the Save button or the saveDocument method is called, the Rich Text Editor converts the document’s content to base64 and invokes the Saving event. If the event is not handled, specify the exportUrl property to save the document on the server side.

You can write the Saved event handler to perform custom actions after a server sends a response to a save request.

The ExportUrl property is not in effect if the document saving is implemented on the client side (the handled property is set to true).

Note

When RichText Editor sends a document to the server, the control encodes the document content in UTF-8. To get the file content in string format, use a converter.

byte[] fileContents = System.Convert.FromBase64String(base64);
string rtfText = Encoding.UTF8.GetString(fileContents);
