####  2、div

```html
    <style type="text/css">
        .clear{clear:both;width:0px;height:0px}
    </style>

<div class="clear"></div>

这种定义的div可以当作换行

3、listbox

动态绑定数据

public class listboxModel
{
    public string listText { get; set; }
    public string listValue { get; set; }

    List<listboxModel> list = new List<listboxModel>();
    list.Add(new listboxModel{listText="SQL",listValue="SQL"});
    list.Add(new listboxModel{listText="Oracle",listValue="Oracle"});
    list.Add(new listboxModel { listText="MySql",listValue="MySql"});

    ListBox1.Items.Clear();

    ListBox1.DataSource = list;
    ListBox1.DataTextField = "listText";
    ListBox1.DataValueField = "listValue";
    ListBox1.DataBind();
}

protected void Page_Load(object sender, EventArgs e)
{
//页面第一次加载的时候
  if(!IsPostBack)
  {
      InitialListBox();

    list.Add(new SexModel {SexText="男D",SexValue="Male" });
    list.Add(new SexModel { SexText="女?",SexValue="Female"});

    DropDownList1.Items.Clear();
    foreach (SexModel sm in list)
    {
        ListItem item = new ListItem();
        item.Text = sm.SexText;
        item.Value = sm.SexText;
        DropDownList1.Items.Add(item);
    }
}

protected void Page_Load(object sender, EventArgs e)

    if(!IsPostBack)
    {
        InitialDropDownList();
        InitialListBox();
