Question

在.net web应用程序中DropDownList如何绑定数据

Answer 1

在Page_Load事件中：if(!IsPostBack){ using (SqlDataAdapter adapter=new SqlDataAdapter("select id,name from category",new SqlConnection("你的连接字符串")) //这里假设有category表 { DataTable dt = new DataTable(); adapter.Fill(dt); Dropdownlist1.DataSource = dt; Dropdownlist1.DataTextField = "name"; Dropdownlist1.DataValueField = "id"; Dropdownlist1.DataBind(); }}

Answer 2

dropDownList.DataSource=数组 dropDownList.DataSource=DataTable对像DataMember.DataMember =DataTable指定列的列名
