Calendar Description:
Calendar is an ASP.NET AJAX extender that can be attached to any ASP.NET TextBox control. It provides client-side date-picking functionality with customizable date format and UI in a popup control. You can interact with the calendar by clicking on a day to set the date, or the "Today" link to set the current date.
In addition, the left and right arrows can be used to move forward or back a month. By clicking on the title of the calendar you can change the view from Days in the current month, to Months in the current year. Another click will switch to Years in the current Decade. This action allows you to easily jump to dates in the past or the future from within the calendar control.
The page uses the culture setting English (United States) which was specified by the browser. The page properties have Culture="auto" and UICulture="auto" set to enable the same. See this MSDN article for more information. The ScriptManager on this Calendar demo page has EnableScriptGlobalization="true" and EnableScriptLocalization="true".
Calendar Properties:
The calendar associated with a button has been initialized with this code. The properties in italic are optional:
<ajaxToolkit:Calendar runat="server"
TargetControlID="Date1"
CssClass="ClassName"
Format="MMMM d, yyyy"
PopupButtonID="Image1" />
TargetControlID - The ID of the TextBox to extend with the calendar.
CssClass - Name of the CSS class used to style the calendar. See the Calendar Theming section for more information.
Format - Format string used to display the selected date.
PopupButtonID - The ID of a control to show the calendar popup when clicked. If this value is not set, the calendar will pop up when the textbox receives focus.
PopupPosition - Indicates where the calendar popup should appear at the BottomLeft(default), BottomRight, TopLeft, TopRight, Left or Right of the TextBox.
SelectedDate - Indicates the date the Calendar extender is initialized with.
Calendar Theming
You can change the look and feel of Calendar using the Calendar CssClass property. Calendar has a predefined set of CSS classes that can be overridden. It has a default style which is embedded as a WebResource and is a part of the Toolkit assembly that has styles set for all the sub-classes. You can find them in the Toolkit solution, in the "AjaxControlToolkit\Calendar\Calendar.css" file. If your CssClass does not provide values for any of those then it falls back to the default value. To customize the same the user would have to set the CssClass property to the name of the CSS style and define the styles for the individual classes so that the various elements in a Calendar control can be styled accordingly. The second calendar in the demo above uses the "MyCalendar" style. which sets the Calendar container style as follows.
.MyCalendar .ajax__calendar_container {
border:1px solid #646464;
background-color: lemonchiffon;
color: red;
}
