The string displayed in the edit box when the edit value equals null, System.DBNull.Value or RepositoryItemDateEdit.NullDate (for DateEdit controls).

NullText

Use the RepositoryItemTextEdit.NullValuePrompt property to display a hint in an editor when its value is not set.

NullValuePrompt

See the RepositoryItemTextEdit.NullValuePrompt topic to learn more about the difference between these properties.

The NullText property is not supported for a CheckedComboBoxEdit control. This control's value cannot be set to null.

For lookup editors (LookUpEditBase descendants), the NullText property's default value is obtained from localization resources (the localization string ID is "StringId.LookUpEditValueIsNull"). The property's default value is "[EditValue is null]" in the English culture.
