/**
 *
 * 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 <b>DateFormat</b> property. Valid formats are the combination of the
 * following tokens,
 *
 * ```
 *  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
 *  -----------------------------------------
 * ```
 *
 * TDatePicker has four <b>Mode</b> to show the date picker popup.
 *
 *  # <b>Basic</b> -- 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.
 *  # <b>Clickable</b> -- 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.
 *  # <b>Button</b> -- Shows a button next to the text input, clicking on the
 *                     button shows the date, button text can be by the
 *                     <b>ButtonText</b> property
 *  # <b>ImageButton</b> -- Shows an image next to the text input, clicking on
 *                          the image shows the date picker, image source can be
 *                          change through the <b>ButtonImageUrl</b> property.
 *
 * The <b>CssClass</b> property can be used to override the css class name
 * for the date picker panel. <b>CalendarStyle</b> property sets the packages
 * styles available. E.g. <b>default</b>.
 *
 * The <b>InputMode</b> property can be set to "TextBox" or "DropDownList" with
 * default as "TextBox".
 * In <b>DropDownList</b> mode, in addition to the popup date picker, three
 * drop down list (day, month and year) are presented to select the date .
 *
 * The <b>PositionMode</b> 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.
