Notes

Containers do not need a DBKit layout

A DBKit.Container does not have to be placed on a DBKit.Window. It is a layout in its own right: place it on any window, set its Database and TableName, and add DBKit controls to it.

Connecting the layout to a database

Add a DatabaseConnection object to your project and assign it to the Database property in the Layout Editor. That is how the layout knows which database connection to use.

How controls find their columns

If a control's ColumnName is blank, the control's own name is used as the column name. You only need to set ColumnName if you want a different column or cannot name the control the same as the column.

Filtering and sorting rows

Use Where to filter which rows are loaded and OrderBy to sort them. Provide just the expression in each case, not the SQL keywords: set Where to Country = 'USA' rather than WHERE Country = 'USA', and OrderBy to LastName rather than ORDER BY LastName.

Localization

Localize the layout's user-facing text (the delete-confirmation and unsaved-changes dialog text and the confirmation button captions) the standard Xojo way: assign a dynamic constant to each property and provide translations for as many languages as you need, or localize the property values directly.
