Invoke the Model Editor for the MySolution.Module project. Navigate to the Views | MySolution.Module.BusinessObjects node. Expand the Contact_DetailView child node. It contains the Items and Layout child nodes. To view and modify the current layout of the Contact Detail View editors, select the Layout node. The property list to the right will be replaced with a design surface that imitates the Contact Detail View. To modify the editor arrangement, right-click the View's empty space and choose Customize Layout.
The Customization Form will be invoked. In the invoked form, you can drag editors to the required positions.
Follow the graphical prompts that indicate the item's new location. In addition, you can remove and restore View Items. Drag the required item from the Detail View to the Customization Form to remove the item, and drag the item from the Customization Form to the Detail View to add it.
To view the layout tree for View Items, click the Layout Tree View tab on the Customization Form. You can right click a tree item and invoke a context menu, allowing you to hide the Customization Form, reset the layout, create a tabbed group, etc. (See the image below.)
