In ActiveGrid Applications, all submits on the Page are associated with one or more defined
Actions. When a user clicks on a button, link or other submit, the client sends a request to the ActiveGrid Server. The request contains the identity of the
Action along with any data that the user submitted.
In order to add a button or link to a Page, you must first define the associated
Action. After you define the
Action you want to invoke, you can insert the button or link that invokes it. A button or link can have more than one
Action. The server executes the
Actions sequentially, in the order you list them.
The Message Ref property on button and links identifies the “selected” object. When the user clicks the button or link, the object identified by the Message Ref property becomes the “selected” object in the request (
Identifying a Single Object in a List of Objects).
For example, a navigational link to another Page would have a Ref property value of
null().
