IsFilled Property

Summary

Indicates whether this OMR field is filled.

Syntax
C#
C++/CLI
Python
public bool IsFilled {get; set;} 
public:  
   property bool IsFilled 
   { 
      bool get() 
      void set(bool value) 
   } 
IsFilled # get and set (OMRField) 

Property Value

Indicates whether this OMR field is filled.

Field

The following values are possible:

Value Meaning
TRUE The OMR is filled.
FALSE The OMR is not filled (the FilledBound = UnFilledBound).
