Populate RadioButtonList with XmlDataSource
Now create a Web Form name XmlDataSource.aspx. Then place an XmlDataSource control and a RadioButtonList control. Here we populate the RadioButtonList control with XmlDataSource control. When someone selects a option then it shows in label control. The source code of XmlDataSource.aspx file is below.


<%@ Page Language="C#" %>

<!DOCTYPE html>

<script runat="server">
    protected void RadioButtonList1_SelectedIndexChanged(object sender, System.EventArgs e) {
        Label1.Text ="Your favorite control: "+ RadioButtonList1.SelectedItem.Text.ToString();
    }
</script>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>XmlDataSource Simple Example</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:XmlDataSource ID="XmlDataSource1" runat="server" 
            DataFile="~/App_Data/StandardToolBoxControls.xml">
        </asp:XmlDataSource>
        <asp:Label ID="Label1" runat="server" Font-Size="Medium" ForeColor="Fuchsia">
        </asp:Label>
        <br /><br />
        <asp:Label ID="Label2" runat="server" Text="Select your most favorite Standard ToolBox Control" Font-Size="Large" ForeColor="DarkRed">
        </asp:Label>
        <asp:RadioButtonList
             ID="RadioButtonList1"
             runat="server"
             DataSourceID="XmlDataSource1"
             DataMember="Control"
             DataTextField="Name"
             RepeatColumns="4"
             AutoPostBack="true"
             OnSelectedIndexChanged="RadioButtonList1_SelectedIndexChanged"
             >
        </asp:RadioButtonList>
    </div>
    </form>
