Remarks

The search feature allows you to filter and highlight the search text in List Box data. If the search text contains multiple words separated by space characters, the words can be treated as a single condition or as individual conditions grouped by the Or or And operator.

Set the SearchTextParseMode property to a value of the ListSearchTextParseMode enumerator to specify how the List Box component treats search words.
