Obviously, It wont work . You are trying to Cast a LinkButton to an integer.

Seems that your intention was to Cast the LinkButton text value or the Gridview Row Value to integer. Change it accordingly.

Check Karthik's solution ..Take the Text from linkbutton which will be a string value which you ned to convert to int.
