EditText is the value of the text for the edit control after it is formatted using the EditMask. Before the text is fully entered into a masked edit control, the EditText includes a blank character for each unentered character. As characters are entered, the blank characters in the EditText are replaced by the values that the user types. 

If literal mask characters are included in the text, and no character is substituted for blanks, the values of EditText and Text are the same.
