<asp:DataList ID="dlstTest" runat="server" OnItemDataBound="dlstTest_ItemDataBound" >
<ItemTemplate >
<asp:RadioButton ID="rdbDataList" runat="server" />

< asp:Label id="lblnm" runat="server" Text="Name:"> </asp:Label >

< asp:Label ID="lblName" runat="server" Text='<%# Eval("Name") %>'></asp:Label>

function CheckRdb(spanChk){

var oItem = spanChk.children;
var theBox= (spanChk.type=="radio") ?
spanChk : spanChk.children.item[0];
xState=theBox.unchecked;
elm=theBox.form.elements;
for(i=0;iif(elm[i].type=="radio" &&
elm[i].id!=theBox.id)
{
elm[i].checked=xState;
}
}
