==============
As most of you know, New Dynamics AX (AX 7) is entirely browser based so forms are quite different from all previous versions of AX forms. One of the areas of forms affected by the move to browser-based forms is form parts. Form parts are those small things on AX 2012 forms on the right-hand side of the form and at the bottom of list pages that display extra bits of information regarding the currently selected record. In AX 7 the parts on the right-hand side of the screen stay where they are but the preview pane, which is the form part at the bottom of a list page, has been eliminated.
In Visual Studio in a form’s designer, you may see a few preview panes (for example on the SalesTableListPage) but the part is not displayed when the form is rendered. The list page design pattern no longer supports it and the preview pane is not displayed.
