Searching for Records in Borland TDBGrid

Helllo,

I am trying to find solution to click in specific row in the grid. I am really new in this, i had found the article https://support.smartbear.com/testcomplete/docs/app-objects/specific-tasks/grids/borland-tdbgrid/index.html and tried to use the script provided but i get an error  'Python runtime error. AttributeError: The object does not support this property or method'. 

Can someone help me?

Thanks in advance
