Question

I am currently invoking client-side functions and server-side functions from the same button click thus…

<asp:Button id="myButton"
            runat="server"
            cssclass="myButtonClass"
            text="Do Stuff"
            onclick="Do_Foo" 
            OnClientClick="Do_Bar();"/>

I was wondering if something analagous was possible for a radio button list…

<asp:RadioButtonList id="myRadioButtonList"
                     runat="server"
                     AutoPostBack="True"
                     onselectedindexchanged="Do_Fum"
                     ...er...something here?>
    <asp:ListItem ...or here perhaps?... Value="0">First Button</asp:ListItem>
    .
    .

You can use following approach: paste code below in page’s Page_PreRender event handler

foreach (ListItem item in myRadioButtonList.Items)
{
    item.Attributes["onclick"] = "if(!confirm('Are you sure?'))return false";
}
