You need to set CommandName and CommandArgument properties of LinkButton and handle RowCommand event of GridView.

I did it.I Access the specific cell but when I changed the Text of that cell(which is Linkbutton),Linkbutton will convert to Label!!!!!!!!!

use FindControl method to get the reference of that linkButton.

thx for your reply.I did it too,but it returns NULL:

LinkButton L = (LinkButton)GridView1.Rows[0].Cells[0].FindControl("hypShowDetail");
L.Text="XXXX";

but L returns Null!!!!
Am I wrong?
