RadioButtonList

1.用法

<asp:RadioButtonList ID="rblIsLock" runat="server" RepeatDirection="Horizontal" RepeatLayout="Flow">

                        <asp:ListItem Selected="True" Value="0">启用 </asp:ListItem>

                        <asp:ListItem Value="1">禁用 </asp:ListItem>

                    </asp:RadioButtonList><label>*禁用的用户将无法登录</label>

2.RadioButtonList控件里的每项asp:ListItem添加单独的ToolTip也就是鼠标悬停的提示信息

protected void Page_Load(object sender, EventArgs e)

    {

        RadioButtonList1.Items[0].Attributes.Add("title", "111");

        RadioButtonList1.Items[1].Attributes.Add("title", "111");

    }

3.使用复杂绑定完成 CheckBoxList 和 RadioButtonList 控件的绑定

View Code
前台:



<body>



    <form id="form1" runat="server">

    <div>

        <asp:RadioButtonList ID="RadioButtonList1" runat="server">

        </asp:RadioButtonList>

        <br />

        <br />

        <asp:CheckBoxList ID="CheckBoxList1" runat="server">

        </asp:CheckBoxList>

    </div>

    </form>



</body>





后台:



 protected void Page_Load(object sender, EventArgs e)

        {

            string sql = "select * from province";

            DataTable dt = SQLHelper.ExecuteDataTable(sql);

            this.RadioButtonList1.DataSource = dt;

            this.RadioButtonList1.DataTextField = "Provinces";

            this.RadioButtonList1.DataValueField = "PId";

            this.RadioButtonList1.DataBind();



            this.CheckBoxList1.DataSource = dt;

            this.CheckBoxList1.DataTextField = "Provinces";

            this.CheckBoxList1.DataValueField = "PId";

            this.CheckBoxList1.DataBind();

        }





SQLHelper类:

public static DataTable ExecuteDataTable(string sql, params SqlParameter[] pms)

    {

        DataTable dt = new DataTable();

        SqlDataAdapter adapter = new SqlDataAdapter(sql,connStr);

        if (pms != null)

        {

            adapter.SelectCommand.Parameters.AddRange(pms);

        }

        adapter.Fill(dt);

        return dt;

    }

4.当选项被选中时,更改选中选项的前景色

View Code
 <asp:RadioButtonList ID="rblIsLock" runat="server" AutoPostBack="true" OnSelectedIndexChanged="rblIsLock_SelectedIndexChanged" 

 RepeatDirection="Horizontal" RepeatLayout="Flow">

                        <asp:ListItem Selected="True" Value="0">启用 </asp:ListItem>

                        <asp:ListItem Value="1">禁用 </asp:ListItem>

                    </asp:RadioButtonList><label>*禁用的用户将无法登录</label>



后台:

 protected void rblIsLock_SelectedIndexChanged(object sender, EventArgs e)

    {

        var rbl = sender as RadioButtonList;

        HighliehgSelectedItem(rbl);

    }



    private void HighliehgSelectedItem(RadioButtonList rbl)

    {

        foreach (ListItem li in rbl.Items)

        {

            if (li.Selected)

            {

                li.Attributes.Add("style", "color: red;");

            }

        }

    }
