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 three <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. * # <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 <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 . * * The <b>PositionMode</b> property can be set to "Top" or "Bottom" with default * as "Bottom".
