Select the option value be defult on page load

Content

Hi,

Creating a webpage where the table is dropped and this table is bind with a Service connection get method. Added an extra column on a table and dropped a checkboxset component. In the external service, there is a field "flag" having values true and false.

I wanted all the checkboxes to select if the falg value is true.

Can someone help how to achieve this?
