Mask Test: No Process On Initialize
It should be noted that this setting can cause the Mask control to display odd results if it's used in a case where the initial value that is placed inside the field does not closely resemble a value that would have otherwise been placed in the field by the Mask Control. For example, if you place 0000000000 in the field below [instead of (000) 000-0000], and attempt to key new values in the middle of it, the masking will appear to only work halfway. This is not a normal case and should not be used unless you plan to properly format these values in your backend before they make it to the client.
