Run External Command Activity


Runs a command on the client. The command must exist/be implemented by the client application.

Inheritance Hierarchy:



This activity executes a specified command in the client application.

In a Workflow:

The Silverlight Viewer contains a command called PanToPoint that accepts an ESRI.ArcGIS.Client.Geometry.Geometry object as its parameter. To invoke this command from within a workflow, you could use the RunExternalCommand activity and specify PanToPoint as the Command Name and your geometry object as the Command Parameter.

The command you wish to invoke must be implemented in the target client application. Not all client application commands can be called from a workflow.

For complete lists of supported commands and their parameters, see the Geocortex SDK for HTML5 or the Geocortex Viewer for Silverlight Administrator and Developer Guide.
