This is the same that i am using but, find control return a null. I checked in many places, it says for dynamically created control the control is not saved across post back.

I have followed the solution given in the link attached in my question. i am creating a column of checkbox which i want to access on a button click, unfortunately these checkbox fields created dynamically are not being found by the row.FindControl("ceheckBoxId").
