一直想实现onmouseover和onmouseout应用于RadioButtonList或CheckBoxList控件上，今晚终于有时间实现它。此功能就是当鼠标经过时RadioButtonList或CheckBoxList每一个Item时，让Item有特效显示，离开时，恢复原样。可以看到效果：
RadioButtonList效果：
CheckBoxList效果：
这资实现数据，Insus.NET准备了五行（Five Phases）
创建一个对象[Five Phases]:
FivePhases.cs using System; using System.Collections.Generic; using System.Linq; using System.Web;/// <summary> /// Summary description for FivePhases /// </summary> public class FivePhases {private int _ID;private string _Name;public int ID{get { return _ID; }set { _ID = value; }}public string Name{get { return _Name; }set { _Name = value; }}public FivePhases(){//// TODO: Add constructor logic here// }public FivePhases(int id, string name){this.ID = id;this._Name = name;} }
View Code private List<FivePhases> GetFivePhases(){List<FivePhases> ListFH = new List<FivePhases>();FivePhases fh = new FivePhases();fh.ID = 1;fh.Name = "木";ListFH.Add(fh);fh = new FivePhases();fh.ID = 2;fh.Name = "火";ListFH.Add(fh);fh = new FivePhases();fh.ID = 3;fh.Name = "土";ListFH.Add(fh);fh = new FivePhases();fh.ID = 4;fh.Name = "金";ListFH.Add(fh);fh = new FivePhases();fh.ID = 5;fh.Name = "水";ListFH.Add(fh);return ListFH;}
此时，你可以拉一个RadioButtonList或是CheckBoxList控件至网页中，此例以RadioButtonList控件为例。
View Code <asp:CheckBoxList ID="RadioButtonListFivePhases" runat="server" RepeatDirection="Horizontal"></asp:CheckBoxList>
然后在cs绑定数据：
View Code using System.Data.OleDb; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using Insus.NET;public partial class _Default : System.Web.UI.Page {protected void Page_Load(object sender, EventArgs e){if (!IsPostBack)Data_Binding();}private void Data_Binding(){this.RadioButtonListFivePhases.DataSource = GetFivePhases();this.RadioButtonListFivePhases.DataTextField = "Name";this.RadioButtonListFivePhases.DataValueField = "ID";this.RadioButtonListFivePhases.DataBind();}}
还得准备鼠标的over与out样式：
View Code <style type="text/css">.overStyle {font-weight: bold;color: #f00;}.outStyle {font-weight: normal;color: none;}</style>
在Javascript中实现每个Item有onmouseover和onmouseout事件，因此还得写Javascript脚本，放于<head>内。
View Code <script type="text/javascript">function windowOnLoad() {var rbl = document.getElementById('<%= RadioButtonListFivePhases.ClientID %>');var labels = rbl.getElementsByTagName('label');for (var i = 0; i < labels.length; i++) {var lbl = labels[i];lbl.onmouseover = function () {this.className = 'overStyle';};lbl.onmouseout = function () {this.className = 'outStyle';};}}window.onload = windowOnLoad;</script>
