Example

The following example expands the current MapView's extent by 50 percent and assigns the new envelope to the map extent. The code assumes an existing MapView object.

C#	Copy Code
ESRI.ArcGIS.ADF.IMS.Geometry.Envelope newEnvelope = mapView.Extent.Expand(50); mapView.Extent = newEnvelope;

Visual Basic	Copy Code
Dim newEnvelope As ESRI.ArcGIS.ADF.IMS.Geometry.Envelope _ = mapView.Extent.Expand(50) mapView.Extent = newEnvelope

Remarks

This method enlarges the Envelope by the given percentage. The percentage value is based on the input envelope. The new envelope has the same center as the input envelope.

The expandPercentage value must be greater than or equal to zero.
