<com:TContent ID="body" > <h1 id="2301">TDatePicker</h1> <com:DocLink ClassPath="System.Web.UI.WebControls.TDatePicker" /> <p id="280245" class="block-content"><tt>TDatePicker</tt> 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 <tt>DateFormat</tt> property. Valid formats are the combination of the following tokens: <com:TTextHighlighter Language="text" CssClass="source block-content" id="code_280103"> Character Format Pattern (en-US) --------------------------------------------------------------------- d day digit dd padded day digit e.g. 01, 02 M month digit MM padded month digit MMM localized abbreviated month names, e.g. Mar, Apr MMMM localized month name, e.g. March, April yy 2 digit year yyyy 4 digit year --------------------------------------------------------------------- </com:TTextHighlighter> <p id="280246" class="block-content"> The date of the date picker can be set using the <tt>Date</tt> or <tt>Timestamp</tt> properties. The <tt>Date</tt> property value must be in the same format as the pattern specified in the <tt>DateFormat</tt> property. The <tt>Timestamp</tt> property only accepts integers such as the Unix timestamp. </p> <p id="280247" class="block-content"> TDatePicker has three <tt>Mode</tt> to show the date picker popup.</p> <ul id="u1" class="block-content"> <li><tt>Basic</tt> - Only shows a text input, focusing on the input shows the date picker.</li> <li><tt>Button</tt> - Shows a button next to the text input, clicking on the button shows the date, button text can be by the <tt>ButtonText</tt> property.</li> <li><tt>ImageButton</tt> - Shows an image next to the text input, clicking on the image shows the date picker, image source can be change through the <tt>ImageUrl</tt> property.</li> </ul> <p id="280248" class="block-content">The <tt>CssClass</tt> property can be used to override the CSS class name for the date picker panel. The <tt>CalendarStyle</tt> property changes the overall calendar style. The following <tt>CalendarStyle</tt> values are available:</p> <ul id="u2" class="block-content"> <li><tt>default</tt> - The default calendar style.</li> </ul> <p id="280249" class="block-content">The <tt>InputMode</tt> 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 . When <tt>InputMode</tt> equals "DropDownList", the order and appearance of the date, month, and year will depend on the pattern specified in <tt>DateFormat</tt> property. </p> <p id="280250" class="block-content">The popup date picker can be hidden by specifying <tt>ShowCalendar</tt> as false. Much of the text of the popup date picker can be changed to a different language using the <tt>Culture</tt> property. </p> <p id="280251" class="block-content">The calendar picker year limit can be set using the <tt>FromYear</tt> and <tt>UpToYear</tt> properties where <tt>FromYear</tt> is the starting year and <tt>UpToYear</tt> is the last year selectable. The starting day of the week can be changed by the <tt>FirstDayOfWeek</tt> property, with 0 as Sunday, 1 as Monday, etc. </p> <p id="280252" class="block-content"><b>Note 1:</b> If the <tt>InputMode</tt> is "TextBox", the <tt>DateFormat</tt> should only <b>NOT</b> contain <code>MMM</code> or <code>MMMM</code> patterns. The server side date parser will not be able to determine the correct date if <code>MMM</code> or <code>MMMM</code> are used. When <tt>InputMode</tt> equals "DropDownList", all patterns can be used.</p> <p id="280253" class="block-content"><b>Note 2:</b> When the <tt>TDatePicker</tt> is used together with a validator, the <tt>DateFormat</tt> property of the validator must be equal to the <tt>DateFormat</tt> of the <tt>TDatePicker</tt> <b>AND</b> must set <tt>DataType</tt>="Date" on the validator to ensure correct validation.
