Customizing the metamodel : Keywords for USRPROPS : ASGRID
  
ASGRID
The ASGRID command specifies that a ListOf property is presented in a table, or grid. ASGRID must have an Edit Type that is ListOf. Otherwise, System Architect emits a warning when you reopen the encyclopedia and ignores the ASGRID keyword.
Example
Definition "Use Case"
{CHAPTER "Steps"
PROPERTY "Use Case Steps" { EDIT COMPLETE ListOf "Use Case
Step" KEYED BY { "Package", "Use Case Name":Name, Name}
ASGRID LENGTH 1200 } }
Using ASGRID with keyed definitions
Key properties of a definition are not shown in a grid formed by an ASGRID command. In the example above, each Use Case Step’s package name or Use Case name is not shown in the grid.
Limitation of ASGRID
You cannot use ASGRID in a LISTOF that refers to a definition that is in a COMPLETE ListOf in another definition. For example, you can add a ListOf.
