在Repeater中嵌套使用Repeater
在 一般的网站中浏览类别的用户控件通常都位于大多数 ASP.NET 页的左边,它使用户能够按类别快速的查找产品。最近遇到一个客户,因为在他网站上展示的产品并不多,所以要求在原有类别浏览的基础上将产品也加进去。一来 更方便,二来加长了左部导航栏的长度使页面更协调。原有的分类导航栏是由Repeater实现的,现在需要在每一个分类下加入该类的商品信息,于是我想到 了在原有Repeater中嵌套Repeater。实现界面如下:
前台页面部分:
<asp:Repeater id="rptCategories" runat="server">
<HeaderTemplate>
<table width="100%" border="0" cellspacing="0" cellpadding="0">
</HeaderTemplate>
<ItemTemplate>
<!--分类名称-->
<tr><th><%# DataBinder.Eval(Container.DataItem, "TypeName") %></th></tr>
<!--分类下的产品-->
<asp:Repeater id="rptProduct" runat="server">
<ItemTemplate>
<tr><td><a href='ProductInfo.aspx?Id=<%# DataBinder.Eval(Container.DataItem, "ID") %>'><%# DataBinder.Eval(Container.DataItem, "ProductName") %></a></td></tr>
</ItemTemplate>
</asp:Repeater>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
后台代码部分(部分代码):
//在绑定分类品名时,绑定分类下的产品
private void rptCategories_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
BLL.Products products =new BLL.Products();
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
Repeater rptProduct = (Repeater) e.Item.FindControl("rptProduct");
//找到分类Repeater关联的数据项
DataRowView rowv = (DataRowView)e.Item.DataItem;
//提取分类ID
int CategorieId = Convert.ToInt32(rowv["ID"]);
//根据分类ID查询该分类下的产品,并绑定产品Repeater
rptProduct.DataSource = products.GetProductsByCategorieId(CategorieId);
rptProduct.DataBind();
}
}
