3.7 Report Columns and Form Items

Most region types have an associated data source with a set of columns APEX infers automatically.

Page Designer makes working with the columns of report regions and grids easy, as well as with page items in a form region. This is true even when new use cases require updating your application data model.

• Configuring Report Region Columns
  If a region lets you configure settings on its data source columns, then they appear in Page Designer under a heading in the component tree.
• Synchronizing Column Changes
  If your region's data source needs to work with additional columns, or different set of them, your page can automatically adapt.
• Deleting or Commenting Out Columns
  Often, your table includes more columns than you need to show in a particular region. In that situation, you have two options: you can delete the column from the region's column list, or you can comment it out.
• Page Items in a Form Region
  When your page includes a Form region, the Page Designer detects and displays a page item for each column in the data source in the Region Body slot.
• Flexible Form Page Item Layout
  While report regions control the layout of their columns, form regions have a flexible layout.
