public virtual bool CanSelectAll {get;}

'Declaration
 
Public Overridable ReadOnly Property CanSelectAll As Boolean

'Usage
 
Dim instance As AnnAutomation
Dim value As Boolean
 
value = instance.CanSelectAll

public:
virtual property bool CanSelectAll {
   bool get();
}

Property Value

true if all objects in this AnnAutomation can be selected; otherwise, false.

If the AnnAutomation contains one or more AnnObject objects, then this property will return true. Selecting an object in AnnAutomation is the equivalent of starting its AnnEditDesigner.

Call the SelectAll method to select all of the automation objects.

For information about grouping and ungrouping, refer to Grouping and Ungrouping Annotation Objects.

This example adds a few objects into an automation and then selects and deselects them.
