i尝试从代码中生成radioputtonlist autopostback，但它也不起作用

i try to make radioputtonlist autopostback from the code but it is not work also


like that:

foreach (DataListItem dli in datalist_iq.Items)
    {
         rblfilteritem = (RadioButtonList)dli.FindControl("RadioButton1");
      // rblfilteritem.AutoPostBack = true;
        a_content = q_object.retrive_a((int)datalist_iq.DataKeys[dli.ItemIndex]);
        rblfilteritem.DataSource = a_content;

        rblfilteritem.DataBind();



    }
    rblfilteritem.AutoPostBack = true;



}
