List - Search

To add a search bar to the List and enable the search functionality, do the following:

  • Set the searchEnabled property to true.

  • Specify the searchExpr property. It is used to compare the search string against a specific field in your data objects. In this example, the search string is compared against the "Name" field.

  • Use the searchMode property to specify whether list items should start with, contain, or match the search string. In this example, you can use the drop-down menu under the List to change the searchMode.
