Repeart控件中嵌套DataList控件 - Arain的DotNet应用与开发公文包 -

Repeart控件中嵌套DataList控件,一般显示数据,网页上都比较喜欢用Datalist因为他很灵活,而且样式好控制.而一些特定的功能需要用到数据控件之间绑定才能实现.但如果在DATALIST中再绑定一个DATALIST呢?这样效率很底.在功能条件允许的情况下,应该更优先的考虑REPERT很DATALIST的嵌套.

下面是我写的一个 Repeart控件中嵌套DataList控件例子

test.aspx

<%#DataBinder.Eval(Container.DataItem,"name") %><%#DataBinder.Eval(Container.DataItem,"title") %>

test.aspx.cs

protected void Page_Load(object sender, EventArgs e) { string sql="select * from nvwa_type order by id"; string connstring="Provider=Microsoft.Jet.OLEDB.4.0;Data Source="+Server.MapPath("~/App_Data/mydate.mdb"); OleDbDataAdapter oda= new OleDbDataAdapter(sql,connstring); DataSet ds=new DataSet(); oda.Fill(ds); this.Repeater1.DataSource = ds; this.Repeater1.DataBind(); } protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { string connstring = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Server.MapPath("~/App_Data/mydate.mdb");

int type_id = Convert.ToInt32(((DataRowView)e.Item.DataItem).Row["id"].ToString());

DataList dl = (DataList)e.Item.FindControl("DataList1"); //找到DataList1控件 if (type_id != 0 && type_id != null) { string sql_p = "select * from nvwa_product where type=" + type_id + " order by id"; OleDbDataAdapter oda = new OleDbDataAdapter(sql_p, connstring); DataSet ds = new DataSet(); oda.Fill(ds); dl.DataSource = ds; dl.DataBind(); }

} }
