关于CheckBoxList的取值问题

Question

我的CheckBoxList是在repeater的ItemDataBound事件里面动态生成的，现在在按钮的添加事件下面应该如何获取CheckBoxList选中的值呢？求助！

Answer 1

贴点源码上来看看吧，应该用FindControl方法可以找到的

Answer 2

遍历repeater
FindControl().
Checkboxlist chkblist=(Checkboxlist)Repeater.Item.FindControl(""); foreach (ListItem items in CheckBoxList1.Items
{
    items.Selected = true;
    //...
}

Answer 3

以前写的一个 。你看下有用么
 for (int i = 0; i < Repeater1.Items.Count; i++)
                {
                    Repeater repeater2 = Repeater1.Items[i].FindControl("Repeater2") as Repeater;
                    if (repeater2 != null)
                    {
                        for (int j = 0; j < repeater2.Items.Count; j++)
                        {
                            CheckBox cb = repeater2.Items[j].FindControl("chkbox2") as CheckBox;
                            cb.Checked = false;
                            Label lbnum = repeater2.Items[j].FindControl("Label1") as Label;
                            for (int h = 0; h < ssid.Length - 1; h++)
                            {
                                if (lbnum.Text == ssid[h].ToString())
                                {
                                    cb.Checked = true;
                                }
                            }                        }
                    }
                }

protected void RepList_ItemDataBound(object sender, RepeaterItemEventArgs e)
        {
            if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
            {  Label lbltype = e.Item.FindControl("lblType") as Label;
                Label lblID = e.Item.FindControl("lblID") as Label;
                Panel pan = e.Item.FindControl("pan") as Panel;
                type =Convert.ToInt32(lbltype.Text);
                DataSet ds = queBll.GetList(0, " id=" + lblID.Text + " ", "");
                string[] d = ds.Tables[0].Rows[0]["question"].ToString().Replace("\r\n", "\r").Split(new char[] { '\r' });                  
                if (type == 28)//找到repeater里面的RadioButtonList  单选
                {
                    RadioButtonList rndanxuan = new RadioButtonList();
                    rndanxuan.ID = "rndanxuan";
                    rndanxuan.DataSource = d;
                    rndanxuan.DataBind();
                    pan.Controls.Add(rndanxuan);
                }
                if (type == 29)
                {
                    RadioButtonList rbdanxuanwenben = new RadioButtonList();
                    rbdanxuanwenben.ID = "rbdanxuanwenben";
                    rbdanxuanwenben.DataSource = d;
                    rbdanxuanwenben.DataBind();
                    pan.Controls.Add(rbdanxuanwenben);
                }
                if (type == 30)
                {
                    CheckBoxList chkduo = new CheckBoxList();
                    chkduo.ID = "chkduo";
                    chkduo.DataSource = d;
                    chkduo.DataBind();
                    pan.Controls.Add(chkduo);
                }
}
}//然后我要在按钮的添加事件下面获取这些选中的值
 protected void bnt_add_Click(object sender, EventArgs e)
        {
            for (int i = 0; i < RepList.Items.Count; i++)
            {
                RadioButton rbl = RepList.Items[i].FindControl("rbdanxuanwenben") as RadioButton;
                if (rbl != null)
                {
                    //记录选中的答案                    if (rbl.Checked)
                    {
                       
                    }
                }
            }
        }
我应该怎么取值呢

Answer 5

目测是 RepList.Items[i].FindControl==null因为你加了Panel soRadioButton rbl = (RepList.Items[i].FindControl("pan") as pannel).FindControl("cb") as RadioButton ;
