Link Ajax is one of the most powerful component in Neptune Application Designer. It will give the possibility to update a container on your screen from another application/container. Our server is optimized for Link Ajax, using XHR and sending only the container content back to the client. Developing complex application with many components and bigger screen, using Link Ajax is a game changer.

If you need a processing event after the Link Ajax is done, please use the Ajax Success event in the attribute tab.



Text content. Possible to enter static text and translate to different languages if needed. Use the translate button to translate.The label can also be binded to an public attribute from the application class.

Source App

Source application the source container is read from. Default is blank and the current application.

Only Serialize this form

To prevent the AJAX call to serialize all forms inside the application. Checking this will make the client only sending data from the FORM where the Link Ajax is a child.


Binds value for attributes to the object. All valid attributes can be binded.

Format from Application Class:

id="demo" width="100px"


Binds value for styles to the object. All valid styles can be binded.

Format from Application Class:

width: 100px; length: 200px


If the binded value for this field contains a value, the object will not be rendered from the server to the client. The disable function will also disable all child objects.


The Ajax ID is passed to the method OnAjax in the Application Class to be able to handle different methods depending on the Ajax ID.
