A complete sample project is available at

document.LoadDocument("Documents//Grimm.docx", DevExpress.XtraRichEdit.DocumentFormat.OpenXml);
Shape myTextBox = document.Shapes[0];
// Allow text box resize to fit contents.
myTextBox.TextBox.HeightRule = TextBoxSizeRule.Auto;
SubDocument boxedDocument = myTextBox.TextBox.Document;
int appendPosition = myTextBox.TextBox.Document.Range.End.ToInt();
// Append the second paragraph of the main document to the boxed text.
DocumentRange newRange = boxedDocument.AppendDocumentContent(document.Paragraphs[1].Range);
// Insert an image form the main document into the text box.
boxedDocument.Images.Insert(boxedDocument.CreatePosition(appendPosition), document.Images[0].Image.NativeImage);
// Resize the image so that its size equals the image in the main document.
boxedDocument.Images[0].Size = document.Images[0].Size;
