| ZoomMode | A ZoomMode enumeration value. |
Available values:
| Name | Description |

| Custom | The document zoom factor is defined by the DocumentViewerControl.ZoomFactor property value. |
| ActualSize | Sets the document zoom factor value to 100%. |
| FitToWidth | Sets the document zoom factor value to fit to the width of the widest page in a document. If the bleed box is smaller than the crop box, the FitToWidth provides different result from the FitToVisible mode. |
| FitToVisible | The document zoom factor is calculated to fit to the width of the visible content of a page. The region of the visible page content is defined by the bleed box (see section 14.11.2 of the PDF 32000-1:2008 standard).

using DevExpress.Xpf.DocumentViewer;
// ...
XtraReport1 report = new XtraReport1();
documentPreview.DocumentSource = report;
report.CreateDocument();
documentPreview.ZoomMode = ZoomMode.FitToWidth;
You can also use the ZoomFactor property to specify a custom zoom value. This sets the ZoomMode property to Custom automatically.
The Document Preview’s Toolbar provides commands to zoom a document.
