DocumentLayout.GetFormattedPageCount() Method

Obtains a number of pages for which layout has been already calculated.

Namespace: DevExpress.XtraRichEdit.API.Layout

Assembly: DevExpress.RichEdit.v24.1.Core.dll

NuGet Packages: DevExpress.RichEdit.Core, DevExpress.Win.Navigation

Declaration

C#

public int GetFormattedPageCount()

VB.NET

Public Function GetFormattedPageCount As Integer

Returns

Type	Description
Int32	An integer that is the number of pages in the document layout.

Remarks

Use the GetFormattedPageCount value to get the actual number of formatted pages, because they are formatted asynchronously.

The document layout in RichEditDocumentServer is calculated on demand (the RichEditDocumentServer.LayoutCalculationMode property is set to Manual), so the GetFormattedPageCount method returns 0 after the document is loaded.

You can use the DocumentLayout.GetPageCount() method to retrieve the number of pages in the document.
