This tutorial demonstrates how to attach the C1EventsCalendarExtender to a Panel control, allowing users add events to the calendar.

1. In your Web application, add a standard Panel control to the main content of  your page.
2. Click the Panel smart tag and select Add Extender from the Tasks menu.
3. In the Extender Wizard, select C1EventsCalendarExtender and click OK. A C1EventsClanedarExtender control is added to the page and the TargetControlID is set to TextBox1.

<cc1:C1EventsCalendarExtender ID="Panel1_C1EventsCalendarExtender"

        runat="server" Colors="red,darkorchid,green,blue,cornflowerblue,yellow,bronze"

        SelectedDate="2012-02-09" TargetControlID="Panel1"

        VisibleCalendars="Default,Home,Work">

    </cc1:C1EventsCalendarExtender>

In the next step you will set some of the extender properties.
