DocumentViewerBase.IsMetric Property

Namespace: DevExpress.DocumentView.Controls

Assembly: DevExpress.Utils.v22.1.dll


public bool IsMetric { get; set; }

Property Value

Type Description

true, to use the metric system for measurements made in the document’s preview; otherwise, false. The default value is set to the System.Globalization.RegionInfo.CurrentRegion.IsMetric property value.


Set this property’s value to false to measure units in inches (imperial), and to true to measure in millimeters (metric), when the document is previewed.



This example illustrates how to set the system of measurement exposed by the tooltips in a print preview that is shown when manually resizing a document’s margins.

The following methods toggle the measurement system from imperial to metric and vice versa, by switching the DocumentViewerBase.IsMetric property.

private void SetMillimeterMeasurement() {
    documentViewer1.IsMetric = true;

private void SetInchMeasurement() {
    documentViewer1.IsMetric = false;
