ASPxCallback.EnableCallbackCompression Property

Gets or sets whether callback result compression is enabled.

Namespace: DevExpress.Web

Assembly: DevExpress.Web.v21.1.dll


public bool EnableCallbackCompression { get; set; }

Property Value

Type Default Description


true to enable callback result compression; otherwise, false.


When operating via callbacks, the ASPxCallback control enables callback results generated for the control on the server to be sent compressed for compression-enabled browsers, improving application performance. Callback result compression provides faster transmission time between the server side and compression-enabled browsers.

When callback result compression is enabled, the ASPxCallback checks whether the target browser that sent the requested callback is compression-enabled (by analyzing if the Accept-Encoding request header matches the gzip or deflate value). If content encoding is allowed by the browser, the ASPxCallback compresses (using the corresponding encoding scheme) the callback result as it is generated for the control on the server, and sends the compressed response to the browser.


The EnableCallbackCompression property is not in effect if IIS HTTP compression is enabled.


The callback compression is enabled for the entire web site by default. To learn more, see the Callback Compression topic.
