/**
 *
 * TDatePicker class.
 *
 * TDatePicker displays a text box for date input purpose.
 * When the text box receives focus, a calendar will pop up and users can
 * pick up from it a date that will be automatically entered into the text box.
 * The format of the date string displayed in the text box is determined by
 * the DateFormat property. Valid formats are the combination of the
 * following tokens,
 *
 * <code>
 * Character Format Pattern (en-US)
 * -----------------------------------------
 * d day digit
 * dd padded day digit e.g. 01, 02
 * M month digit
 * MM padded month digit
 * MMMM localized month name, e.g. March, April
 * yy 2 digit year
 * yyyy 4 digit year
 * -----------------------------------------
 * </code>
 *
 * TDatePicker has four Mode to show the date picker popup.
 *
 * # Basic -- Only shows a text input, focusing on the input shows the
 * date picker. This way you can access the popup using only
 * the keyboard. Note that because of this, TAB-bing through
 * this control will automatically select the current date if
 * no previous date was selected. If you close the popup (eg.
 * pressing the ESC key) you'll need to un-focus and re-focus
 * the control again for the popup to reappear.
 * # Clickable -- Only shows a text input, clicking on the input shows the
 * date picker. This mode solves the two small problems of the
 * Basic mode. It was first introduced in Prado 3.2.
 * # Button -- Shows a button next to the text input, clicking on the
 * button shows the date, button text can be by the
 * ButtonText property
 * # ImageButton -- Shows an image next to the text input, clicking on
 * the image shows the date picker, image source can be
 * change through the ButtonImageUrl property.
 *
 * The CssClass property can be used to override the css class name
 * for the date picker panel. CalendarStyle property sets the packages
 * styles available. E.g. default.
 *
 * The InputMode property can be set to "TextBox" or "DropDownList" with
 * default as "TextBox".
 * In DropDownList mode, in addition to the popup date picker, three
 * drop down list (day, month and year) are presented to select the date .
 *
 * The PositionMode property can be set to "Top" or "Bottom" with default
 * as "Bottom". It specifies the position of the calendar popup, relative to the
 * input field.
