Radiobuttonlist default selected item

[jsc0624]

Hi Guys,

I have a problem with the radiobuttonlist.

If I am going to edit the content of the radiobuttonlist manually I can easily set the default selected value.

<asp:RadioButtonList ID="rblItems" runat="server" RepeatDirection="Horizontal" AutoPostBack="True">
       <asp:ListItem Selected="True">Item 1</asp:ListItem>
       <asp:ListItem>Item 2</asp:ListItem>
       <asp:ListItem>Item 3</asp:ListItem>
</asp:RadioButtonList>

But how can I do this if the radiobuttonlist is bound in the database. This code below returns empty string.

rblItems.SelectedIndex = 1;

Thanks
