ListBox，CheckBoxList，DropDownList，RadioButtonList的常见数据绑定

 void way1()
   {
    DropDownList1.Items.Add("c#");
    DropDownList1.Items.Add("vb");
    DropDownList1.Items.Add("c");
    DropDownList1.Items.Add("java");
    ListBox1.Items.Add("c#");
    ListBox1.Items.Add("VB");
    ListBox1.Items.Add("C++");
    ListBox1.Items.Add("JAVA");
    
    CheckBoxList1.Items.Add("c#");
    CheckBoxList1.Items.Add("VB");
    CheckBoxList1.Items.Add("javascript");
    CheckBoxList1.Items.Add("php");
    RadioButtonList1.Items.Add("asp");
    RadioButtonList1.Items.Add("php");
    RadioButtonList1.Items.Add("jsp");
    RadioButtonList1.Items.Add("ajax");
   }
哈斯表法：
void way2()
   {
    Hashtable ht=new Hashtable();
    ht.Add("1","c#");
    ht.Add("2","C++");
    ht.Add("3","php");
    ht.Add("4","CGI");
    this.DropDownList2.DataSource=ht;
    DropDownList2.DataTextField="Value";
    DropDownList2.DataValueField="Key";
    DropDownList2.DataBind();
    this.ListBox2.DataSource=ht;
    ListBox2.DataTextField="value";
    ListBox2.DataValueField="key";
    ListBox2.DataBind();
    this.CheckBoxList2.DataSource=ht;
    CheckBoxList2.DataTextField="value";
    CheckBoxList2.DataValueField="key";
    CheckBoxList2.DataBind();
    this.RadioButtonList2.DataSource=ht;
    RadioButtonList2.DataTextField="value";
    RadioButtonList2.DataValueField="key";
    RadioButtonList2.DataBind();
   }
SortedList方法：
   void way3()
   {
    SortedList s1=new SortedList();
    s1.Add("1","haha");
    s1.Add("2","hehe");
    s1.Add("3","xixi");
    s1.Add("4","heihei");
    this.DropDownList3.DataSource=s1;
    DropDownList3.DataTextField="value";
    DropDownList3.DataValueField="key";
    DropDownList3.DataBind();
   }
用数据对象dataread方法：
void way4()
   {
    OleDbConnection cn=new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+Server.MapPath("sailing.mdb")+";Persist Security Info=False");
    cn.Open();
    OleDbCommand cmd=new OleDbCommand();
    cmd.Connection=cn;
    cmd.CommandText="select RoleName,RoleID from Role";
    OleDbDataReader dr=cmd.ExecuteReader();
    while(dr.Read())
    {
     ListItem li=new ListItem(dr[0].ToString(),dr[1].ToString());
     this.ListBox4.Items.Add(li);
    }
    dr.Close();
    cn.Close();
   }
用数据集法：
     OleDbConnection cn=new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+Server.MapPath("sailing.mdb")+";Persist Security Info=False");
     cn.Open();
     OleDbCommand cmd=new OleDbCommand();
     cmd.Connection=cn;
     cmd.CommandText="select RoleName,RoleID from Role";
     OleDbDataAdapter adp=new OleDbDataAdapter(cmd);
     DataSet ds=new DataSet();
     adp.Fill(ds);

     this.CheckBoxList4.DataSource=ds.Tables[0];
     this.CheckBoxList4.DataTextField=ds.Tables[0].Columns[0].ToString();
     this.CheckBoxList4.DataValueField=ds.Tables[0].Columns[1].ToString();
     this.CheckBoxList4.DataBind();

还有一种数组法：

<%@ Page Language="C#" AutoEventWireup="True" %>
<Script language="C#" runat="server">
void Page_Load(Object Sender,EventArgs e){
ArrayList array=new ArrayList();
array.Add("Windows");
array.Add("Linux");
array.Add("unix");
CheckBox_1.DataSource=array;
CheckBox_1.DataBind();
RadioList_1.DataSource=array;
RadioList_1.DataBind();
}
</Script>
<form id="Form_1" runat="server">
<ASP:checkboxList ID="CheckBox_1" runat="server"/>
<input id="Button_1" type="Button" value="CheckButton" runat="server"/>
<asp:radiobuttonlist ID="RadioList_1" runat="server"/>
<input id="Button_2" type="Button" value="RadioButton" runat="server"/>
</form>
