给DataList模板中的LINKBUTTON增加一个属性
我在DataList模板中放了一个LINKbutton,想点击LINKBUTTON时,弹出一个对话框,问是否真的要删除
代码为:
if (!IsPostBack)
{
LinkButton lbtn = (LinkButton)Page.Form.FindControl( "lb_delete ");
if (lbtn != null)
{
lbtn.Attributes.Add( "onclick ", "return confirm( '你确定要删除当前这个组的照片吗? ') ");
}
这样写,为什么找不到呢?返回一个空值NULL
把page.Form换成DataList1也不行啊,哪位高手帮我看看啊,谢了啊
弄得了,马上给分
