Paging Repeater control

The Repeater control is an extremely simple server-bound control in the ASPNET control. It only provides templates without paging or more attributes. Similar to the datalist control, datalist provides richer style control. Here we will use the concise repeater for extension to implement the paging function similar to the DataGrid. The main logic is paging and the button for adding pages to the control. The main class relation of the control is to inherit the Repeater control. In addition, the ipostbackeventhandler interface is also implemented to trigger the paging function on the server side. The control also provides the pagerstyle attribute to set paging text and paging styles. The paging part is not extended in depth. If you are interested, you can continue to expand it.
