Can we store the a child field value when any field in the row get clicked?

Is there any way that we can capture the value of a text field when any of the field in the table get clicked.
It is possible with one way around when user clicks to edit the row by using:

frappe.ui.form.on(“ChildDoctypeName”, “form_render”, function(frm, cdt, cdn){

But what if the user clicks in the grid instead of editing the row?
