Creating a Single Record Detail Page

Data views are instances of data controllers placed on pages. The application generator automatically configures data views to start presentation with a list of records. Each data controller defines grid1 view to render a list of records.

Customers grid view.

If business requirements call for a single record to be visible to an end user, then the grid view becomes unnecessary.

A developer can specify that the form view editForm1 for the data view on the page. The form will be displayed initially. The data view will switch back to grid1 as soon as user initiates Insert, Update, Delete, or Cancel actions. The action state machine of data controllers does not define specific actions that must follow any of these commands. The client library will simply display the first view of the data controller.

The first view in Customers data controller is 'grid1'.

View ‘grid1’ happens to be first, and users will see a list of data records.

The developer has the option to add multiple actions that would select editForm1 after Insert, Update, Delete, or Cancel actions. The easiest solution is to move editForm1 to the first position.

To preserve the default functionality of the data controller on other pages, you may want to clone the controller, and have the clone configured to display data in the form view editForm1.
