edit link column added every time edit link is clicked

Jul 15 2015 8:08 PM
C# Winform  Desktop Application
 
I've a grid view where I've added a Edit link column from code behind. The edit link works fine when the data is loaded for the first time. But when I do search on the same grid view, the edit link is added every time I press the Edit link.
 
I know the cause of the problem, please see the comment in the code . But I do not know where should I keep my edit function so that it appears in my grid view correctly. Please see my code and suggest.
