Dynamic radiobutton set an added listitem as selected

Question

Hi I have a dynamic radiobutton

aspx-file

<asp:RadioButtonList ID="MoneyTransfer" runat="server" CssClass="darkgrey">
</asp:RadioButtonList>   

aspx.cs-file

MoneyTransfer.Items.Add(new ListItem("BankTransfer","BankTransfer", true));
MoneyTransfer.Items.Add(new ListItem("PayPal","PayPal", true));

What do I have to do to get the first listItem to be the selected one ?

Answer 1

Set Selected Property of listItem to true.

ListItem ls =new ListItem("BankTransfer", "BankTransfer" ,true);
            ls.Selected=true;
            ListItem ls2 = new ListItem("PayPal", "PayPal", true);
            MoneyTransfer.Items.Add(ls);
            MoneyTransfer.Items.Add(ls2);
