Solution 1

C#

Label compname = (Label)DetailsView1.Rows[1].Celles[0].FindControl("complbl");

that is the right syntax, but the error is pointing to a different source. Try doing this one:

C#

if(DetailsView1.Rows.Count != 0)
{
   Label compname = (Label)DetailsView1.Rows[1].Celles[0].FindControl("complbl");
}

Regards,
Eduard
