treeview

贴两个关于treeview的
<script language="javascript">
<!--
//初始化选中节点
function initchecknode()
{
var node=TreeView1.getTreeNode("1");
node.setAttribute("Checked","true");
setcheck(node,"true");
FindCheckedFromNode(TreeView1);
}
//oncheck事件
function tree_oncheck(tree)
{
var node=tree.getTreeNode(tree.clickedNodeIndex);
var Pchecked=tree.getTreeNode(tree.clickedNodeIndex).getAttribute("checked");
setcheck(node,Pchecked);
document.all.checked.value="";
document.all.unchecked.value="";
FindCheckedFromNode(TreeView1);
}
//设置子节点选中
function setcheck(node,Pc)
{
var i;
var ChildNode=new Array();
ChildNode=node.getChildren();

if(parseInt(ChildNode.length)==0)
return;
else
{
for(i=0;i<ChildNode.length;i++)
{
var cNode;
cNode=ChildNode[i];
if(parseInt(cNode.getChildren().length)!=0)
setcheck(cNode,Pc);
cNode.setAttribute("Checked",Pc);
}
}
}
//获取所有节点状态
function FindCheckedFromNode(node) {
var i = 0;
var nodes = new Array();
nodes = node.getChildren();

for (i = 0; i < nodes.length; i++) {
var cNode;
cNode=nodes[i];
if (cNode.getAttribute("Checked"))
AddChecked(cNode);
else
AddUnChecked(cNode);

if (parseInt(cNode.getChildren().length) != 0 ) {
FindCheckedFromNode(cNode);
}
}
}
//添加选中节点
function AddChecked(node) {
document.all.checked.value += node.getAttribute("NodeData");
document.all.checked.value += ',';
}
//添加未选中节点
function AddUnChecked(node) {
document.all.unchecked.value += node.getAttribute("NodeData");
document.all.unchecked.value += ',';
}

treeview中如何在服务器端得到客户端设置后的节点选中状态
<script language="C#" runat="server">
private void Button1_Click(object sender, System.EventArgs e)
{
Response.Write(TreeView1.Nodes[0].Checked);
}
</script>
<script language="javascript">
function set_check()
{
var nodeindex = "0";
var node=TreeView1.getTreeNode(nodeindex);
node.setAttribute("Checked","True");
TreeView1.queueEvent('oncheck', nodeindex);
}
</script>
