Context Menu

  • 3 minutes to read

The Layout Control provides the built-in Customization Context Menu that delivers design-time and runtime customization capabilities. You and your end-user can rename and hide layout items, combine them into groups and tabbed groups, set size constraints, etc.

At design time, you can right-click any layout item, layout group or tabbed group to access customization commands appropriate for the clicked item. At runtime, the Customization Context Menu is available in Default Customization Mode.


The customization menu is context dependent, so different commands are available when different types of layout items are clicked:

The context menu for a single selected regular item


The context menu for a number of continuously selected items


The context menu for a Layout Group


The context menu for a Tabbed Group


Customization Commands

The available customization commands are listed in the table below:



Add Empty Space Item

Adds a new resizable empty item (Empty Space Item).
