Find control for Data rows only Like:

protected void mygrid_RowDataBound(object sender, GridViewRowEventArgs e)
{

  if (e.Row.RowType == DataControlRowType.DataRow)
      {
           string empid = "";         

           empid = ((Label)e.Row .FindControl("lblname")).Text;
       }
 }

The "Object reference to instance of an object" error is probably because no control named lblname was found for the current row.

Maybe you need to check the type of the row, e.Row.RowType = DataControlRowType.DataRow so that you are not searching for the control in the header row.

  Label lbl = (Label)e.Row.Cells[2].FindControl("lblCreatedBy");
             lbl.Text = "ABC";
