最简单的Asp.Net 2.0 TreeView的Checkbox级联操作

直接在TreeView的属性上加入：OnClick="OnTreeNodeChecked()"

或者：MyTree.Attributes.Add("OnClick", "OnTreeNodeChecked()");

页面写入以下JavaScript:
<script language ='javascript' type='text/javascript'>
function OnTreeNodeChecked()
{
var ele = event.srcElement;
if(ele.type=='checkbox')
{
var childrenDivID = ele.id.replace('CheckBox','Nodes');
var div = document.getElementById(childrenDivID);
if(div==null)return;
var checkBoxs = div.getElementsByTagName('INPUT');
for(var i=0;i<checkBoxs.length;i++)
{
if(checkBoxs[i].type=='checkbox')
checkBoxs[i].checked=ele.checked;
}
}
}
</script>
