Properties
item
The ListView
item currently assigned to this cell. Child elements of <Cell>
can bind properties to it used the bind-<widgetProperty>='item.itemProperty
syntax.
Type: | ItemType |
Settable: | No |
Change Event: | itemChanged |
itemCheck
A callback that must return true
for any item this cell can display. This is used to determine which <Cell>
template to use when multiple are given in a <ListView>
element. May be used instead or in addition to itemType
.
Setting this property also enables runtime item type checks, so it can be useful to set it even if only one <Cell>
element is present.

Default: | null |
Settable: | Yes |
Change Event: | itemCheckChanged |
itemIndex
The index (within the items
of ListView
) of the item currently assigned to this cell.
Type: | number |

selectable
