ASP.NET 2.0 repeater控件实现多列完美显示，比网上其它方法要好。
前台代码：
  

                    
                        
                            
                          
                        
                        
                            
                        
                        

<%#Eval("Typename") %>

                    
                

后台代码：
public partial class wztypes : System.Web.UI.Page
{
    int i = 1;
    protected void Page_Load(object sender, EventArgs e)
    {
        Repeater1.DataSource = zxwztypeman.getwztypelist();
        Repeater1.DataBind();
    }
    protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        if ((e.Item.ItemType == ListItemType.Item) || (e.Item.ItemType == ListItemType.AlternatingItem))
        {
            if ((i % 4 == 0) && (i >= 4))//是否换行
            {
                e.Item.Controls.Add(new LiteralControl(""));
            }
            i++;
        }
        if (e.Item.ItemType == ListItemType.Footer)//在末尾补齐表格单元格
        {
            string s = string.Empty ;
            if ((i >= 4) && ((i - 1) % 4 > 0))
            {
                for (int z = 0; z < (4-(i - 1) % 4); z++)
                {
                    s += " ";
                }
                e.Item.Controls.AddAt(0, new LiteralControl(s));
            }
        }
      
    }
}
