Hi

Calendar control is one of the most required client controls in the web development. This extender can be attached to any textbox. It provides client-side date-picking functionality with customizable date format and UI in a popup control. The animation while choosing the year, month and date is really cool.

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 basic properties of the extender are TargetControlID which takes the id of a textbox, cssClass to define the css of the calendar. With the help of the format property we can define the format of the date input. We can also use the PopupButtonID we can define a button (Image, Link or normal) control on click of which the Calendar control will be popped. If this property is not set then the calendar control will be popped on the focus of the given textbox.

Hope this helps
Thanks
