Gets or sets a value indicating whether client-side callbacks are used for sorting and paging operations.
Assembly: System.Web (in System.Web.dll)
By default, when a sorting or paging operation is performed, the GridView control posts back to the server to perform the operation. When the 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.
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.
