AjaxRemoteServiceOptions Interface

Provides options for customizing the AjaxRemoteService.

Declaration

export interface AjaxRemoteServiceOptions

Remarks

The Ajax remote service is a default IRemoteService<TResponse> implementation that exchanges information between client and server sides. You can get different information from a server (data sources, export information, a dashboard model), obtain a dashboard request time, pass custom HTTP headers and so much more.

Refer to the following topics for information on how to set the server’s URL and pass a custom Authorization header from the client:

Properties

headers Property

Specifies an object of additional header key/value pairs to send along with requests using the XMLHttpRequest transport.

Remarks

Note

The client-side dashboard control uses form.submit to export the entire dashboard or a dashboard item. This approach doesn’t allow the application to send HTTP headers from client to server side. In this case, the dashboard control adds the <input type="hidden"> element to the form for each HTTP header from the headers collection. The hidden input element has the same ID as the HTTP header’s name. The header value is sent to the server side as the value of the corresponding field. You can use the HttpRequest.Form collection to access the hidden fields’ values on the server side.
