{
this.RadioButtonList1.Items[1].Attributes.Add("onclick", "if(!confirm('您真的要点我吗?')){document.getElementById('" + this.RadioButtonList1.ClientID+ "_0').checked=true;event.returnValue=false;}");
}
{
this.RadioButtonList1.Items[1].Attributes.Add("onclick", "if(!confirm('您真的要点我吗?')){document.getElementById('" + this.RadioButtonList1.ClientID+ "_0').checked=true;event.returnValue=false;}");
}
