下面的范例使用一个 XML 文件来填充 RadioButtonList 的数据
<%@ Import Namespace="System.Data" %> <script runat="server"> sub Page_Load if Not Page.IsPostBack then dim mycountries=New DataSet mycountries.ReadXml(MapPath("countries.xml")) rb.DataSource=mycountries rb.DataValueField="value" rb.DataTextField="text" rb.DataBind() end if end sub sub displayMessage(s as Object,e As EventArgs) lbl1.text="You selected: " & rb.SelectedItem.Text end sub </script> <form runat="server"> <asp:RadioButtonList id="rb" AutoPostBack="True" runat="server" onSelectedIndexChanged="displayMessage" /> <asp:label id="lbl1" runat="server" /> </form>
