请问，如何实现treeview控件的节点点击响应事件？

Question

找不到事件的入口？大家都怎么使用treeview控件呢？

Answer 1

TreeView.SelectIndexChange这样可以不？

Answer 2

1.使用javaScript
.net中Page_load加
TreeView1.Attributes.Add("onclick","GetAttribute()");页面加
<script language="javascript">
function GetAttribute()
{
document.Form1.txtDescription.value='';
document.Form1.txtTypeID.value=Trim(TreeView1.getTreeNode(TreeView1.clickedNodeIndex).getAttribute("ID"));
document.Form1.txtTypeName.value=Trim(TreeView1.getTreeNode(TreeView1.clickedNodeIndex).getAttribute("Text"));
document.Form1.txtDescription.value=Trim(TreeView1.getTreeNode(TreeView1.clickedNodeIndex).getAttribute("NodeData"));
}
</script>2.用SelectIndexChange

<script language="javascript">
<!--
function TrvModel_DblClick(tree)
{
window.document.Form1.Isdbclick.value="true";
var node=tree.getTreeNode(tree.clickedNodeIndex);
document.Form1.TreeIndex.value = tree.clickedNodeIndex;
window.document.Form1.submit();
}
-->
</script>

Answer 5

如果是XML生成的树.可以在节点里class,然后在class里使用behavior指向HTC文件里加事件

Answer 6

用VS的话在TreeView 属性框的事件里有的呀，selectedindexchanged

Answer 7

用VB.net的话在TreeView属性框的事件里也是一样。，TreeView_selectedindexchanged()

Answer 8

To:beyland88()if (myFlag=="2")
{    .....}
if (myFlag=="4")
{
 ......
}
是什么意思?　学习。看不懂。先收藏!
              

Answer 9

不用那么复杂吧TreeView.SelectIndexChange 就可以捕捉到啊
