Hello masda,

You can use ‘checkItem’ method after the widget initialization. Please, refer to the API Documentation for more information.

Hi masda,

If you are using checkboxes in jqxTree you should use checked instead selected property. Please, find the following example which shows how to check the checkboxes when you initialize the widget and how to get checked items when you are using JSON data.
