How to: Change the Measurement System Exposed in the Print Preview

• Jan 15, 2024

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.

C#

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

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

VB.NET

Private Sub SetMillimeterMeasurement()
    DocumentViewer1.IsMetric = True
End Sub

Private Sub SetInchMeasurement()
    DocumentViewer1.IsMetric = False
End Sub
