Property Value

The zoom percentage expressed as a value, 5.0 to 5000.0. The default is 100.0, which corresponds to 100.0%.


Setting this property causes the DocumentViewer control to zoom to the specified value.

The Zoom property must be a value between 5.0 to 5000.0 (inclusive), which corresponds to a percentage range 5.0% to 5000.0%.

Actions or commands that require a layout update may change the Zoom property setting. For example, changing the value of MaxPagesAcross, calling the FitToHeight method, or invoking the FitToHeightCommand can cause the Zoom setting to change.
