#Parameters

Name Type Description
state ICommandUIState

An object implementing the ICommandUIState interface that defines the current status of a command in the overall context of the application user interface.

#Remarks

Before assessing the availability of a command, restore its default status against the overall context of the application user interface (imposed by the Command.CreateDefaultCommandUIState method), using the UpdateUIState method.

To evaluate the current applicability of a command, check the ICommandUIState property values.

Next, trigger a command’s execution by calling the PdfViewerCommand.ForceExecute method.
