Property Value

true if Empty values should be converted to a null reference (Nothing in Visual Basic); otherwise, false. The default is true.

Sometimes the user may enter an empty string for a field value when updating or inserting records. Use the ConvertEmptyStringToNull property to specify whether an empty string value is automatically converted to a null reference (Nothing in Visual Basic) when the data field is updated in the data source

NoteNote:

The ImageField class displays a null reference (Nothing in Visual Basic) as empty strings by default. To display a different value, set the NullDisplayText property.
