TreeView触发TreeNodeCheckChanged事件

1、客户端

<script type="text/javascript" language="javascript">
function postBackByObject()
{
var o = window.event.srcElement;
if (o.tagName == "INPUT" && o.type == "checkbox")
{
__doPostBack("","");
}
}
</script>

2、服务器端

if (!Page.IsPostBack)
{
TVMenu.Attributes.Add("onclick", "postBackByObject()");
}
