请教在datalist中找控件的问题

Question

请各位帮我看看
怎么就找不到datalist中的控件呢我是这样找控件的:
CheckBoxList CBL = (CheckBoxList)DataList1.FindControl("CBL_Check");是这样写的吗?
可我得出来的CBL是null

Answer 1

贴HTML，并且请楼主说明想实现什么

Answer 2

CheckBox check = (CheckBox)grid.FindControl(checkID);

Answer 3

用DataListItem 查找.
private void DataList_ItemDataBound(object sender, System.Web.UI.WebControls.DataListItemEventArgs e)
{
CheckBoxList CBL = (CheckBoxList)e.ItemFindControl("CBL_Check");
 
}

Answer 4

CheckBoxList CBL = (CheckBoxList)DataList1.items[i].FindControl("CBL_Check");
i为你要找控件的行数

Answer 5

我的目的是想做一个动态绑定 
   
    CheckBoxList CBL = (CheckBoxList)DataList1.FindControl("CBL_Check");        CBL.DataSource = ds2;
        CBL.DataTextField = ds2.Tables[0].Columns["code"].ToString();
        CBL.DataValueField = ds2.Tables[0].Columns["DescriptionCN"].ToString();
        CBL.DataBind();
<asp:DataList ID="DataList1" runat="server" RepeatColumns="4">
            <ItemTemplate>
                <asp:CheckBoxList ID="CBL_Check" runat="server">
                </asp:CheckBoxList>
                <asp:TextBox ID="TB_percent" runat="server" Width="70px"></asp:TextBox>
            </ItemTemplate>
        </asp:DataList>

Answer 6

private void DataList1_ItemDataBound(object sender, System.Web.UI.WebControls.DataListItemEventArgs e)
{
if(e.Item.ItemIndex>-1)
{
CheckBoxList CBL = (CheckBoxList)e.Item.FindControl("CBL_Check");
CBL.DataSource = ds2;
CBL.DataTextField = ds2.Tables[0].Columns["code"].ToString();
CBL.DataValueField = ds2.Tables[0].Columns["DescriptionCN"].ToString();
CBL.DataBind(); }
}
