Rotation

RadPdfViewer provides functionality for rotating the pages of the loaded document. You can programmatically rotate the document pages through the RadPdfViewer class.

Rotation Using RadPdfViewer

RadPdfViewer has a Rotate() method intended to rotate the pages of the loaded document at the specified angle relative to its initial position. The method takes a single argument of type RotationAngle. Alternatively, you can use the RotationAngle property.

RotationAngle is an enumeration that specifies the angle at which the document should be rotated. The possible values are Degrees0, Degrees90, Degrees180, Degrees270.

RotationAngle

this.radPdfViewer1.Rotate(Telerik.WinControls.UI.RotationAngle.Degrees90);

Me.RadPdfViewer1.Rotate(RotationAngle.Degrees90)

The current angle at which the pages are rotated can be retrieved using the read-only RotationAngle property of RadPdfViewer.
