try this
  protected void Gridviewselectbus_RowCommand(object sender, GridViewCommandEventArgs e)
    {
      if (e.CommandName == "Up")
      {
        int index = Convert.ToInt32(e.CommandArgument);
        if (index == 0)
        {

        int value = Convert.ToInt32(dt.Rows[index]["Index"].ToString());
        dt.Rows[index]["Index"] = Convert.ToInt32(index) - 1;
        dt.Rows[index - 1]["Index"] = value;
        dt.DefaultView.Sort = "Index";
        dt.AcceptChanges();
        dtnew = dt.Copy();
        Gridviewselectbus.DataSource = dt;
        Gridviewselectbus.DataBind();

        for (int i = 0; i <= Gridviewselectbus.Rows.Count - 1; i++)

      }
      if (e.CommandName == "Down")
      {
        int index = Convert.ToInt32(e.CommandArgument);
        dt = (DataTable)Session["dt"];
        if (Convert.ToInt16(index + 1) == dt.Rows.Count)
        {

          return;
        }
        int value = Convert.ToInt32(dt.Rows[index]["Index"].ToString());
        dt.Rows[index]["Index"] = Convert.ToInt32(dt.Rows[index]["Index"].ToString()) + 1;
        dt.Rows[index + 1]["Index"] = value;
        dt.AcceptChanges();
        dt.DefaultView.Sort = "Index";
        dt.AcceptChanges();
        dtnew = dt.Copy();
        Gridviewselectbus.DataSource = dt;
        Gridviewselectbus.DataBind();
        dt.AcceptChanges();
        for (int i = 0; i <= Gridviewselectbus.Rows.Count - 1; i++)
        {
          dtnew.Rows[i]["Lname"] = Gridviewselectbus.Rows[i].Cells[0].Text;

        }
        Session["dt"] = dtnew;
        Label1.Text = string.Empty;
      }
    }
}

protected void btnDeleteSelected_Click(object sender, EventArgs e)

{

  foreach (GridViewRow row in GridView1.Rows)

  {

 

  if (((CheckBox)row.FindControl("checkBox1")).Checked == true)

  {

    /* Get Table Id From Row */

    string id = GridView1.Rows[row.RowIndex].Cells[0].Text;

 

    /* delete from database */

 

    SqlConnection con = new SqlConnection("Connection String");

    con.Open();

 

    SqlCommand comm = new SqlCommand("delete from TableName where id='" + id + "'", con);

    comm.ExecuteNonQuery();

  }

  }

 

  /* Refresh the Grid*/

}

Try like this=

protected void chkInactivate_OnCheckedChanged(object sender, EventArgs e)
    {
      CheckBox chkStatus = (CheckBox)sender;
      GridViewRow selectedrow = (GridViewRow)chkStatus.NamingContainer;
      Label lblEmpId = (Label)selectedrow.FindControl("lblEmpId");

      string str = lblEmpId.Text;
    }

Try and let me know.
