How to make a parent field readonly in edit mode …?
Hi,
you can disable input manually, using onLightbox event:gantt.attachEvent("onLightbox", function (task_id){
var parent = gantt.getLightboxSection("parent");
var select = parent.node.getElementsByTagName("select")[0];
select.setAttribute("disabled", true);
});
note, that select element does not have a ‘readonly’ attribute, and you’ll have to use a ‘disabled’.

Or you can create a template control and use it for showing parent name:
