后台。aspx.cs
protected void rpt1_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { Repeater rpt2 = (Repeater)e.Item.FindControl("rpt2"); //找到分类Repeater关联的数据项 DataRowView rowv = (DataRowView)e.Item.DataItem; rpt2.ItemDataBound += new RepeaterItemEventHandler(rpt2_ItemDataBound); //最最重要的一句 //提取分类ID cid = Convert.ToInt32(rowv["ID"]); //根据分类ID查询该分类下的产品，并绑定产品Repeater rpt2.DataSource = Pcategory.getP(cid);//数据绑定 rpt2.DataBind(); } } protected void rpt2_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { Repeater rpt3 = (Repeater)e.Item.FindControl("rpt3"); //找到分类Repeater关联的数据项 DataRowView rowvv = (DataRowView)e.Item.DataItem; //提取分类ID cid2 = Convert.ToInt32(rowvv["ID"]); //根据分类ID查询该分类下的产品，并绑定产品Repeater rpt3.DataSource = getrpt3(cid, cid2);//数据绑定 rpt3.DataBind(); } }
