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 += ',';
}
//-->
  </script>



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>
