页面代码:

<asp:Repeater ID="RepSort1" runat="server" OnItemDataBound="RepSort1_ItemDataBound"><ItemTemplate><table><tr><th><a href='Show.aspx?sortid=<%#Eval("ID") %>'><%#Eval("TypeName") %></a></th></tr><tr><td ><%#Eval("ID") %></td></tr><asp:Repeater ID="RepSort2" runat="server" OnItemDataBound="RepSort2_ItemDataBound"><ItemTemplate><tr><td class="mc"><%#Eval("TypeName") %></td><td><asp:Repeater ID="RepSort3" runat="server"><ItemTemplate><a href='#'><%#Eval("TypeName")%></a></ItemTemplate></asp:Repeater></td></tr></ItemTemplate></asp:Repeater></table></ItemTemplate>
</asp:Repeater>

后台代码:

protected void RepSort1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem){Repeater rep = e.Item.FindControl("RepSort2") as Repeater;DataRowView rowv = (DataRowView)e.Item.DataItem;string pid=rowv["id"].ToString();rep.DataSource = GetItem(pid.ToString());rep.DataBind();}
}protected void RepSort2_ItemDataBound(object sender, RepeaterItemEventArgs e)
{if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem){Repeater rep = e.Item.FindControl("RepSort3") as Repeater;DataRowView rowv = (DataRowView)e.Item.DataItem;string pid = rowv["id"].ToString();rep.DataSource = GetItem(pid.ToString());rep.DataBind();}
}public DataSet GetItem(string pid)
{SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["con"].ConnectionString);SqlCommand com = new SqlCommand("select * from [P-Type] where pid="+pid, con);SqlDataAdapter da = new SqlDataAdapter(com);DataSet ds = new DataSet();da.Fill(ds);return ds;
