本文提供了一个使用C#实现的DataList绑定示例，通过创建数据源并设置DataList的各项属性来展示不同的布局效果，适合ASP.NET初学者学习。

DataList绑定代码 MSDN的好东东。适合初学者。就像俺这样的基础薄弱者大家见笑了嘿

[C#]
<script runat="server">

      ICollection CreateDataSource()
      {
         DataTable dt = new DataTable();
         DataRow dr;

         dt.Columns.Add(new DataColumn("StringValue", typeof(string)));
         for (int i = 0; i < 10; i++)
         {
            dr = dt.NewRow();
            dr[0] = "Item " + i.ToString();
            dt.Rows.Add(dr);
         }

         DataView dv = new DataView(dt);
         return dv;
      }

      void Page_Load(Object Sender, EventArgs e)
      {
         if (!IsPostBack)
         {
            DataList1.DataSource = CreateDataSource();
            DataList1.DataBind();
         }
      }

void Button1_Click(Object Sender, EventArgs e)
{

         if (DropDown1.SelectedIndex == 0)
            DataList1.RepeatDirection = RepeatDirection.Horizontal;
         else
            DataList1.RepeatDirection = RepeatDirection.Vertical;
         if (DropDown2.SelectedIndex == 0)
            DataList1.RepeatLayout = RepeatLayout.Table;
         else
            DataList1.RepeatLayout = RepeatLayout.Flow;
         DataList1.RepeatColumns=DropDown3.SelectedIndex+1;
         if ((Check1.Checked ==true) &&
            (DataList1.RepeatLayout == RepeatLayout.Table))
         {
            DataList1.BorderWidth = Unit.Pixel(1);
            DataList1.GridLines = GridLines.Both;
         }
         else
         {
            DataList1.BorderWidth = Unit.Pixel(0);
            DataList1.GridLines = GridLines.None;
         }
      }
