DocumentLayout.DocumentFormatted Event
Fires after the document layout is calculated.
Namespace: DevExpress.XtraRichEdit.API.Layout
Assembly: DevExpress.RichEdit.v20.1.Core.dll
Declaration
Event Data
The DocumentFormatted event's data class is EventArgs.
Remarks
Handle this event to check layout-dependent information, data and objects.
We do not recommend using this event to edit the document. Handle the RichEditControl.ContentChanged (RichEditControl.ContentChanged for WPF) or RichEditControl.DocumentLoaded (RichEditControl.DocumentLoaded for WPF) event instead.
IMPORTANT
The DocumentFormatted event handler is running in a background (non-UI) thread. Use the RichEditControl.BeginInvoke or Dispatcher.BeginInvoke (WPF) method to avoid concurrency issues. Access the Dispatcher.BeginInvoke method using the RichEditControl.Dispatcher property.
WinForms Example

Dim pageCount As Integer = richEditControl1.DocumentLayout.GetFormattedPageCount()
For i As Integer = 0 To pageCount - 1
Dim visitor As New MyDocumentLayoutVisitor()
visitor.Visit(richEditControl1.DocumentLayout.GetPage(i))
Next i
End Sub))
End Sub

MyDocumentLayoutVisitor visitor = new MyDocumentLayoutVisitor();
visitor.Visit(richEdit.DocumentLayout.GetPage(i));
