CanSelectAll Property

Summary

Gets a value indicating whether this AnnAutomation is in a state where all objects can be selected.

Syntax

C#
VB
C++
public virtual bool CanSelectAll { get; } 
  
Public Overridable ReadOnly Property CanSelectAll As Boolean 
public: 
virtual property bool CanSelectAll { 
   bool get(); 
}

Property Value

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

Remarks

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 WPF Annotation Objects.

Example

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