The Repeater control is a data display control that allows you to customize the layout by repeatedly using the specified template for each item displayed in the list.
Compared to GridViews and DataList, Repeater is a lightweight, flexible control that consumes a lot less energy than they do. The drawback is that the function is slightly thin, especially for the binding data source without data, often to use a hidden surface version to display "Temporarily no data" information. It's too much trouble.
The Repeater control's EmptyDataTemplate template has been extended to achieve the same effect.
