Callback Compression

Some DevEpxress web controls allow requests to the server to be made via callbacks. This option decides if the response data generated after processing these callbacks ought to be compressed by the server before posting it to the client.

Declaration

<configuration>
    ...
    <devExpress>
        <compression ... enableCallbackCompression="true" ... />
        ...
    </devExpress>
    ...
</configuration>

Note

In order to use the DevExpress Web.config section, register this section group beforehand.

This option is enabled by default. Note that the callback compression is enabled if Page HTML Compression option is set to true regardless of the enableCallbackCompression property’s value.

Use the enableCallbackCompression property to enable callback compression when the Page HTML Compression option is set to false.
