Mappings Tab

The Mappings tab of the Properties view provides a global view of all the bindings and computation actions related to the selected element in the Form Designer canvas or Outline view.

You can view, edit, and create mappings from the Mappings tab. It displays the values of the source and target fields of the existing mappings in the left and right trees respectively.

Mappings Tab of the Properties View

The details are as follows:

• The right pane displays the bindable properties of the selected target element.
• The left pane displays the bindable source properties to which the target elements are bound. It displays the selected object and its ancestors all the way up to the containing form and also includes the form parameters and data fields.
• The connecting lines represent the existing mappings between the source and target properties.
• The arrow end-point represents unidirectional mappings.
• The red triangle at one end-point of the connecting line represents collapsed mappings.

The default view of the Mappings tab is focussed on the mappings of the selected element.

A set of buttons and filters are provided in the toolbar. Each of these filters has a corresponding toolbar button and a toolbar menu item: both are associated with same filter action. The buttons control the depth to which the source and target trees are expanded. The filters help you to control the properties to be displayed in the source and target panes. The details are explained in the table Toolbar Buttons for the Mappings Tab.
