## Class TDatePicker

Description

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,

      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 three Mode to show the date picker popup.

- Basic -- Only shows a text input, focusing on the input shows the date picker.
- 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 <tt>DropDownList</tt> mode, in addition to the popup date picker, three drop down list (day, month and year) are presented to select the date .
