Select All Button in Table Control Wizard

Hi All,

I have created a table control using wizard and then checked the option for selecting multiple rows using selection column.

As screenshot contains the table control. The highlighted button is the button to select all the rows of the table control. But when I click save button I am unable to find out whether the select all button was clicked or not. On clicking select all button PAI is not getting triggered. Kindly help.

Regards,

Nooru
