System.Web.UI.WebControls Namespace   GridView Class

---

.NET Framework version 2.0

Sets or retrieves a value specifying whether client-side callbacks are used for sorting and paging operations.

Inline	<asp:gridview enablesortingandpagingcallbacks = true | false ... >
Script	GridView.EnableSortingAndPagingCallbacks [ = true | false ]

This property accepts or returns only a boolean value: true to use client-side callbacks for sorting and paging operations; otherwise, false. Default value is false.

By default, when a sorting or paging operation is performed, the GridView control posts back to the server to perform the operation. When the EnableSortingAndPagingCallbacks property is set to true, a service is called on the client to perform sorting and paging operations, which eliminates the need to post back to the server.

NOTE: Not all browsers support this feature. To determine whether a browser supports this feature, use the SupportsCallback property.

All columns in the Columns collection must support callbacks for this feature to work. If the Columns collection contains a column that does not support callbacks, such as TemplateField, a NotSupportedException exception is raised.

The following example demonstrates how to set the EnableSortingAndPagingCallbacks property at design time to enable client-side callbacks for sorting and paging operations.
