Remarks

The items parameter can be an index, a key, or a range of indexes, or an array that contains one or more of these objects.

• An index: a numeric index value (Number)

  The add method adds the item at the specified index (the value of items) to the selection.

• An index: an object that contains an index property that contains a Number

  The add method adds the item at the specified index (the value of items.index) to the selection.

• A key: an object that contains a key property

  If the itemDataSource supports keys, the add method adds the item that has the specified key (the value of items.key) to the selection.

• A range of indexes or keys: an object that implements ISelectionRange

  • If the object contains firstKey and lastKey values, the add method adds the items in the specified range to the selection, starting with the item at firstKey and ending with the item at lastKey.

  • If the object contains firstIndex and lastIndex values, the add method adds the items in the specified index range to the selection, starting with the item at firstIndex and ending with the item at lastIndex.

  • If the object contains both index and key values, the add method uses the key values.
