  • 2 minutes to read

It's possible to use the non-visual RichEditDocumentServer component to adjust the required document settings. Create a new document using RichEditDocumentServer and adjust its page by using the corresponding API.

Refer to the following documentation articles, where you can learn how to set the required properties: Document, DefaultCharacterProperties.

This example demonstrates how to set a document page's landscape, paper kind, margins and font properties.

using DevExpress.XtraRichEdit;

public partial class _Default : System.Web.UI.Page
    protected void Page_Load(object sender, EventArgs e)
         if (!IsPostBack)

    private void NewDocument()
        MemoryStream memoryStream = null;
        ASPxRichEdit1.Open("document" + Guid.NewGuid().ToString(), DocumentFormat.Rtf, () => { 
            RichEditDocumentServer server = new RichEditDocumentServer();
            server.Document.Sections[0].Page.Landscape = false;
            server.Document.Unit = DevExpress.Office.DocumentUnit.Millimeter;
            server.Document.Sections[0].Margins.Left = 0.5f;
            server.Document.Sections[0].Margins.Right = 0.5f;
            server.Document.Sections[0].Margins.Top = 0.5f;
            server.Document.Sections[0].Margins.Bottom = 0.5f;

            server.Document.DefaultCharacterProperties.FontName = "Arial";
            server.Document.DefaultCharacterProperties.FontSize = 12f;
            server.Document.DefaultCharacterProperties.ForeColor = Color.Red;

            server.Document.Sections[0].Page.PaperKind = System.Drawing.Printing.PaperKind.Custom;
            server.Document.Sections[0].Page.Width = 105f;
            server.Document.Sections[0].Page.Height = 297f;

            memoryStream = new MemoryStream();
            server.SaveDocument(memoryStream, DocumentFormat.Rtf);
            return memoryStream.ToArray();
        if (memoryStream != null)
