Hi

I have this radio button list:
 <asp:RadioButtonList ID="rblRefer2Provider" runat="server" RepeatDirection="Horizontal" RepeatLayout="Flow" ClientIDMode="Static">
 <asp:ListItem Text="No" onclick="toggleRefer2Provider2(false);" />
 <asp:ListItem Text="Yes" onclick="toggleRefer2Provider2(true);" />
</asp:RadioButtonList>

Open in new window


Based on another page event I want to select or de select the first item (The No) using JavaScript (not jquery)

I have tried document.getElementById('rblRefer2Provider_0').checked = true; but this doesn't work, but the radio button list doesn't render as such.

How do I do this. I have searched Google but nothing seems elegant or works.
