CheckBox控件中的最重要属性就是checked属性了
下面就是使用checked属性的一个小应用;
先建立一个wed窗体；在窗体中写下这些代码：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %> <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title></title> </head> <body> <form id="form1" runat="server"> <div> <div id="div_chks" runat="server" style="border:1px solid red"> <asp:CheckBox ID="CheckBox1" runat="server" text="看书"/> <asp:CheckBox ID="CheckBox2" runat="server" text="听音乐"/> <asp:CheckBox ID="CheckBox3" runat="server" text="学习"/> <asp:CheckBox ID="CheckBox4" runat="server" text="打篮球"/> <asp:CheckBox ID="CheckBox5" runat="server" text="打羽毛球"/> <asp:CheckBox ID="CheckBox6" runat="server" text="下棋"/> <br /> <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" /> <asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine" Height="89px"></asp:TextBox> </div> </div> </form> </body> </html>
之后就可以设置事件属性了：
代码如下：
using System.Web.UI; using System.Web.UI.WebControls; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { TextBox1.Text = ""; CheckBox _ckb; foreach (Control ctl in div_chks.Controls) { if (ctl is CheckBox) { _ckb = (CheckBox)ctl; if (_ckb.Checked) { TextBox1.Text += _ckb.Text + ","; } } } } }
之后可以看看结果如何咯！！！
