Typically, a Page is loaded when a users clicks a button or link on another Page, triggering an Action that performs some piece of logic and then invokes the Page. Actions are discussed in detail below (Defining Actions in the Custom Action Editor). For now, what you need to know is that some Actions send specific data to the Page and some simply call the Page without sending any data.
1. When the Page is first invoked, the ActiveGrid Server looks at the message generated by the Action that called the Page, if any. The Server uses any data in this incoming message to populate the data in the Page Message for this Page.
2. If the incoming data does not contain a value for a particular element, the Server looks to see if a default value is defined for that element in the Page Message. If it is, the Server populates that element with the default value.
3. The Server then populates Page Variables. Dependent Page Variables are populated after the variables on which they depend.
