9 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.
Tip:
Run the Upgrade Application utility to automatically upgrade legacy forms to the new form region. See Running Application Upgrade.- Understanding Form Types
When creating an application, developers can create four basic form types: editable interactive grid, form, report with form, or master detail. - Creating a Form
Developers can create forms using the Create Application Wizard and Create Page Wizard. - Configuring Lost Update Detection
Prevent form users from overwriting one another by configuring the Lost Update Detection. - 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. - Creating 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 APEX includes BLOB support to enable developers to declaratively upload and download files in forms.
