DateTimeSelector

The DateTime Selector Webcontrol (Server Control) allows you to both display and let users select Dates and Times.

Using DateTime Selector is as simple as dragging the WebControl onto a webform (aspx page) and setting its SelectedDate property.
All dates can be selected without having to postback to the server, unlike the current aspx calendar control. DateTime Selector exposes its main property 'SelectedDate' which is used to set the initial date and retrieve subsequent date selections.
