true to enable automatic updates; otherwise, false.
If the column's filter dropdown is represented as a regular list of items, only one item at a time can be selected. In this instance, selecting an item automatically updates the column's filter and closes the filter dropdown.
If the filter dropdown is represented as a checked list (multiple items can be checked/unchecked simultaneously) or by a custom template, use the ImmediateUpdateColumnFilter property to enable or disable automatic updates. If automatic updates are disabled, the filter is applied after the filter dropdown has been closed.
