写个项目，从数据库中获得的数据绑定值Checkbox，绑定方法如下

//加班设置数据绑定
protected void CheckBoxBind()
  {
    OverTimeBLL overTimeBll = new OverTimeBLL();
    List overTimeList = new List();

    overTimeList = overTimeBll.GetAll();
    if (overTimeList.Count > 0)
    {
      //绑定页面信息
      txtID.Text = overTimeList[0].ID.ToString();
      if (overTimeList[0].IsEarlyValid.ToLower() == "true") cbIsEarlyValid.Checked = true;
      if (overTimeList[0].IsLaterValid.ToLower() == "true") cbIsLaterValid.Checked = true;
      if (overTimeList[0].IsOnlyHoliday.ToLower() == "true") cbIsOnlyHoliday.Checked = true;
      if (overTimeList[0].IsUseTime.ToLower() == "true") cbIsUseTime.Checked = true;
      if (overTimeList[0].IsUseNum.ToLower() == "true") cbIsUseNum.Checked = true;
      txtMinDuration.Text = overTimeList[0].MinDuration.ToString();
    }
  }

然后在protected void Page_Load(object sender, EventArgs e)方法中加入CheckBoxBind()方法，但提交时，如果某一个CheckBox是选中状态，那获得的永远是该checkBox的checked属性为True，后来再三试了，发现自己疏忽了，只要将CheckBoxBind方法放在if (!this.Page.IsPostBack)下即可。

代码如下

if (!this.Page.IsPostBack)
      {
        remindResult.Text = GetRemind();
        //页面数据绑定
        CheckBoxBind();
      }
