Treevi中的checkbox联动选择,以及Treeview的生成（即选择或取消复选框，其自选框同时选择或取消）
前台.aspx加上一段JavaScript代码
// 点击复选框时触发事件
function postBackByObject()
{
var o = window.event.srcElement;
if (o.tagName == "INPUT" && o.type == "checkbox")
{
__doPostBack("","");
}
}
后台.aspx.cs
if (!IsPostBack)
{
TreeView1.Attributes.Add("onclick", "postBackByObject()");//javascript控制checkbox选择框
}
