HTML：

<asp:BoundField DataField="weekofyear" HeaderText="Week" />
<asp:BoundField DataField="supportname" HeaderText="Name"  />
<%--<asp:BoundField DataField="supid" HeaderText="SupportIDName" Visible="false"/>--%>
<asp:TemplateField>
     <ItemTemplate>
          <asp:Label runat="server" Text='<%#Eval("supid") %>' ID="supid" Visible="false"></asp:Label>
     </ItemTemplate>
     <ItemTemplate>
           <asp:CheckBox ID="TicketCompleted" runat="server" AutoPostBack="true" OnCheckedChanged="TicketCompletedCompleted_Click" Checked='<%# Convert.ToBoolean(Eval("TicketCompleted")) %>' />
     </ItemTemplate>
</asp:TemplateField>

C＃

CheckBox chk = (CheckBox)row.FindControl("TicketCompleted");
if (chk.Checked)
{
    string ID = ((Label)row.FindControl("supid")).Text;
}
