Hello Vignesh,

After investigating this further, I determined that the edit of the igTreeGrid is turned off by default. Otherwise you can set the editMode to none, this way editing through the UI is disabled. You can also stop editing with the buttons Cancel and Done, that appear after you start editing the cells or rows.

More information could be found in the ui.igTreeGridUpdating topic in our documentation.

Please let me know whether these suggestions help you achieve your requirement or if you need more information.

Regards,
