Busy property
Declaration
property Busy: Boolean;
Description
Indicates whether a document is currently being initialized, loaded, or parsed.
This property returns True while the control is initializing or loading a document. After the control has finished parsing and displaying the document, it fires a corresponding status event and sets the Busy property to False.
Most properties and methods of the control are not valid while this property returns True. If you attempt to access that properties or call that methods when Busy is True, a failure result is returned.
