10 Developing Forms
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.
