return gridview 中的复选框列表多个值 [asp.net]

Question

我是 asp.net 的新手。我有一个与 table 中的一列 [PBN] 相连的复选框列表 1，它只有两个值，是和否。我需要 return 网格视图中的数据。即使我在复选框列表中 select 是和否，它也只有 return 没有值。我怎样才能 return 这两个值？希望我说清楚了。数据绑定

<asp:CheckBoxList ID="CheckBoxList1" runat="server" DataSourceID="SqlDataSource4" DataTextField="PBN" DataValueField="PBN" OnSelectedIndexChanged="CheckBoxList1_SelectedIndexChanged">
    </asp:CheckBoxList>

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace WebApplication7
{
    public partial class About : Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
        {

        }

        protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            GridView1.Visible = true;
        }

        protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
        {

        }

        protected void CheckBoxList1_SelectedIndexChanged(object sender, EventArgs e)
        {

        }
    }
}

您需要设置 checked/selected 属性

    <asp:CheckBoxList ID="CheckBoxList1" runat="server" DataSourceID="SqlDataSource4" DataTextField="PBN" DataValueField="PBN" OnSelectedIndexChanged="CheckBoxList1_SelectedIndexChanged">

        <asp:ListItem Selected='<%# Eval("PBN") == "Yes"? true : false %>'>Yes</asp:ListItem>
            <asp:ListItem Selected='<%#Eval("PBN") == "No" ? true : false %>'>No</asp:ListItem>

</asp:CheckBoxList>
