how to optimize getRecordsHierarchy

[ryan paulParticipant]

i notice that getRecordsHierarchy is very slow and making the browser tired in loading large data for tree when using getRecordsHierarchy.

is there any way to optimize this approach?

Hi ryan paul,

You can populate the Tree in multiple different ways.

In case you can provide the data in that format, you will bypass other method calls:

           var source = [
                { icon: "../../images/mailIcon.png", label: "Mail", expanded: true, items: [
                    { icon: "../../images/calendarIcon.png", label: "Calendar" },
                    { icon: "../../images/contactsIcon.png", label: "Contacts", selected: true }
                ]
                },
                { icon: "../../images/folder.png", label: "Inbox", expanded: true, items: [
                   { icon: "../../images/folder.png", label: "Admin" },
                   { icon: "../../images/folder.png", label: "Corporate" },
                   { icon: "../../images/folder.png", label: "Finance" },
                   { icon: "../../images/folder.png", label: "Other" },
                ]
                },
                { icon: "../../images/recycle.png", label: "Deleted Items" },
                { icon: "../../images/notesIcon.png", label: "Notes" },
                { iconsize: 14, icon: "../../images/settings.png", label: "Settings" },
                { icon: "../../images/favorites.png", label: "Favorites" }, 
             ];

Please, note that getRecordsHierarchy has 2 flat loops and it just iterates through your data. It should not be the slow part in the code.
