This property applies only to Date controls and the Date portion of the Date/Time control. Select the Date control type to display only the date input field with a   calendar icon. Clicking the calendar to choose the date or hand-typing it, will display the date in the format selected. European date formatting is supported. Allowable Date Formats consist of three different seperators (.- or / or .) and three date display formats (DD/MM/YYYY, MM/DD/YYYY, and YYYY/MM/DD). The default value is MM-DD-YYYY.

On a mobile device, the date picker is typically used to provide a date. If you set a default date in your form it must be formatted as YYYY-MM-dd in order for it to display correctly.

The date format choices are shown below:

Custom groups with rules included when dropped back onto the same or another form, will contain a special "Prefix" property. The property will automatically be given a unique value if you drop the group onto the same form 2 or more times. This ensures that the group controls have unique element name. You can view the impact the prefix has on the element names by viewing the form's schema or the control's property panel. Using the prefix property, you can write a separate rule to manipulate the 2nd or greater instance of the custom control. Refer to this documentation for the details.
