Developers can create a variety of different application forms either manually or by using wizards. Some forms enable users to update a single row in a table, while other forms enable users to update multiple rows in a table.
Understanding Form Types
When creating a database application, developers can create three basic form types: editable interactive grid, form on a table, or a master detail.
Creating a Form
Developers can create forms using a number of wizards including the Create Application Wizard, Create Page Wizard, and Create Region Wizard.
About Making an Interactive Grid Editable
Developers determine whether the underlying data is read-only or editable by users. An interactive grid presents users a set of data in a searchable, customizable report. In an editable interactive grid, users can also add to, modify, and refresh the data set directly on the page.
Managing Master Detail Forms
Developers can create a master detail form with either the Create Application Wizard or the Create Page Wizard.
Validating User Input in Forms
Developers can create validation and an associated error message to check the data a user enters before processing.
Understanding BLOB Support in Forms
Oracle Application Express includes BLOB support to enable developers to declaratively upload and download files in forms.
