DocumentLayout.DocumentFormatted Event

Fires after the document layout is calculated.

Namespace: DevExpress.XtraRichEdit.API.Layout

Assembly: DevExpress.RichEdit.v24.2.Core.dll

NuGet Package: DevExpress.RichEdit.Core

Declaration

C#

public event EventHandler DocumentFormatted

VB.NET

Public Event DocumentFormatted As EventHandler

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.
