從網格視圖復選框更新數據庫

Question

我在webform上有一個網格視圖，其中有一個隱藏字段，其中包含id，如何從id字段中捕獲數據以在我的update語句中使用？ 這就是我的語法看起來像......
HTML

    <asp:GridView runat="server" ID="gridview2" AutoGenerateColumns="false" >
<Columns>
<asp:BoundField DataField="weekofyear" HeaderText="Week" />
<asp:BoundField DataField="supportname" HeaderText="Name" />
<asp:BoundField DataField="supid" HeaderText="SupportIDName" Visible="false"/>
<asp:TemplateField>
    <ItemTemplate>
        <asp:CheckBox ID="TicketCompleted" runat="server" AutoPostBack="true" OnCheckedChanged="TicketCompletedCompleted_Click" Checked='<%# Convert.ToBoolean(Eval("TicketCompleted")) %>' />
    </ItemTemplate>
</asp:TemplateField>
</Columns>

C＃

protected void TicketCompleted_Click(object sender, EventArgs e)
{
foreach (GridViewRow row in dgRD.Rows)
{
    if (row.RowType == DataControlRowType.DataRow)
    {
        //Below captures the checkbox value (yes or no)
        CheckBox chk = (CheckBox)row.FindControl("TicketCompleted");                    
        if (chk.Checked)
        {
            //Here is where I will run the update
        }
    }
}

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;
}
