ASP.net中的Repeater控件嵌套
<asp:Repeater ID="Repeater1" runat="server" OnItemDataBound="Repeater1_ItemDataBound">
<HeaderTemplate><ul></HeaderTemplate>
<ItemTemplate>
<li><%# Eval("cate_name") %>
<asp:Repeater ID="Repeater2" runat="server">
<HeaderTemplate><ul></HeaderTemplate>
<ItemTemplate>
<li><%# Eval("art_title") %></li>
</ItemTemplate>
<FooterTemplate></ul></FooterTemplate>
</asp:Repeater>
</li>
</ItemTemplate>
<FooterTemplate></ul></FooterTemplate>
</asp:Repeater>
后端代码：
protected void Page_Load(object sender, EventArgs e)
{
if(!IsPostBack)
{
using(SqlConnection conn= new SqlConnection())
{
conn.ConnectionString = ConfigurationManager.ConnectionStrings["testdbConnectionString"].ConnectionString;
conn.Open();
using(SqlDataAdapter da = new SqlDataAdapter("select * from category",conn))
{
DataSet ds = new DataSet();
da.Fill(ds);
Repeater1.DataSource = ds;
Repeater1.DataBind();
}
}
}
}
protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
Repeater rep = e.Item.FindControl("Repeater2") as Repeater;
DataRowView rowv = (DataRowView)e.Item.DataItem;
int cate_id = Convert.ToInt32(rowv["cate_id"]);
using (SqlConnection conn = new SqlConnection())
{
conn.ConnectionString = ConfigurationManager.ConnectionStrings["testdbConnectionString"].ConnectionString;
conn.Open();
using (SqlDataAdapter da = new SqlDataAdapter("select * from article where owner_id=" + cate_id, conn))
{
DataSet ds = new DataSet();
da.Fill(ds);
rep.DataSource = ds;
rep.DataBind();
}
}
}
}
两个Repeater的嵌套，通过ID关联嵌套部分，输出如下:
