sunil，

Design.aspx

Hi sunil,

Design.aspx

<div>
    
        <asp:radiobuttonlist id="RadioButtonList1" runat="server" xmlns:asp="#unknown">
            RepeatDirection="Horizontal">
        
    
    </div>

背后的代码:

Code Behind:

protected void Page_Load(object sender, EventArgs e)
   {
       string cs = ConfigurationManager.ConnectionStrings["samplecnstring"].ConnectionString;
       SqlConnection cn = new SqlConnection(cs);
       SqlCommand cmd = new SqlCommand("select countryname from country", cn);
       SqlDataAdapter da = new SqlDataAdapter(cmd);
       DataSet ds = new DataSet();
       da.Fill(ds, "country");

       RadioButtonList1.DataSource = ds;
       RadioButtonList1.DataTextField = "countryname";
       RadioButtonList1.DataValueField = "countryname";
       RadioButtonList1.DataBind();

   }

好好练习，
祝你玩得开心！！！
