Remarks

Use the EnablePagingCallbacks property to specify whether paging operations are performed using client-side callback functions. When enabled, paging is performed using the callback feature, which prevents the need to post the page back to the server.

Note

The client-side paging feature is only supported in Microsoft Internet Explorer 5.5 and later and Netscape 6.0 and later.

The value of EnablePagingCallbacks is stored in view state.
