AccordionNewsList widget: Implement the server-side functionality
After you implement the client-side functionality of the new user widget, you need to implement the code-behind and the logic of the widget.
To implement the required code, in your project, select the new user widget class. In this case, this is the AccrdionNewsList.ascx.cs class.
EXAMPLE: For more information about the code-behind of the widget, see
AccordionNewsList.ascx.cs in Sitefinity documentation-samples on GitHub.
In the code above, the Page_Load method uses the NewsManager to get all the news items that are with status Live and orders them by publishing date in a descending order. Then, the news items are passed to the repeater.
