-/**

- *

- * 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,

- *

- * <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 <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.

+ *
+ * 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,
+ *
+ * <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 <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.
