CheckBox被选中但在后台代码调试中一直为false

Question

protected void bntDelete_Click(object sender, EventArgs e)
{
int count = 0;
string id = "";
string adminID;

    foreach (GridViewRow gr in this.GridView1.Rows)
    {
        CheckBox chk = (CheckBox)gr.Cells[0].FindControl("cbSelect");
        if (chk.Checked)
        {
            adminID = gr.Cells[1].Text;
            if (0 == count)
            {
                id = "(" + int.Parse(adminID);
            }
            else
            {
                id += "," + int.Parse(adminID);
            }
            count++;
        }
    }
    id += ")";

    if (0 == count)
    {
        Response.Write("<script>alert('请选择管理员！');location.href = 'AdminInfoManagement.aspx';</script>");
        return;
    }
    else
    {
        Administrator admin = new Administrator();
        if (admin.DeleteAdminInfo(id))
        {
            Response.Write("<script>alert('删除成功！');location.href = 'AdminInfoManagement.aspx';</script>");
        }
        else
        {
            Response.Write("<scrip>alert('" + admin.ErrorMessage + "');location.href = 'AdminInfoManagement.aspx';</scrip>");
        }
    }
    this.GridView1.DataBind();
    return;
}

    前台代码就是这样的：
    <asp:TemplateField HeaderText="选择">
                      <ItemTemplate>
                          <asp:CheckBox ID="cbSelect" runat="server" />
                      </ItemTemplate>
                      <ItemStyle Width="20px" HorizontalAlign="Center" VerticalAlign="Middle" />
                    </asp:TemplateField>

应该把你前台代码贴出来。
1.看看checkbox是不是设置了value属性。
2.可以通过jquery，当你判断checked之后把value设置成true。
3.如果都不可以，你改改id试试，是不是id和其他重复了
