Definition and Usage
The DataValueField property specifies the data source field to bind to the Value property of each item in the control.
Example
The following example uses an XML file to populate the RadioButtonList data:
<%@ 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>
<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"
