Repeater 简单数据绑定
ASPX页面的Repeater控件：
<asp:Repeater ID="IndexTopMain" runat="server">
<HeaderTemplate>
<!--头-->
<ul>
</HeaderTemplate>
<ItemTemplate>
<!--中间循环部分-->
<li><a href="AritcleDisplay.aspx?id=<%#Eval("id") %>" title="<%#Eval("title") %>" target="_blank"><%#Eval("title") %></a></li>
</ItemTemplate>
<FooterTemplate>
<!--尾-->
</ul>
</FooterTemplate>
</asp:Repeater>
CS文件的绑定
string indexTopMainStr = "select top 9 id,title from Table order by ID desc";
SqlDataAdapter rst = new SqlDataAdapter(indexTopMainStr,conn);
conn.Open();
DataSet rdt = new DataSet();
rst.Fill(rdt);
IndexTopMain.DataSource = rdt;//数据绑定
IndexTopMain.DataBind();
conn.Close();
二：
使用：SqlCommand方式
private void bind()
{
SqlConnection conn = db.CreateConnection();
string sql = "select * from gongsia";
SqlCommand cmd = new SqlCommand(sql,conn );
conn.Open();
Repeater1.DataSource = cmd.ExecuteReader();
Repeater1.DataBind();
conn.Close();
}
