vs2003树控件 显示两层树菜单和树样式表
function ExpandOneTwo()
{
var NodeArray=new Array();
NodeArray=TreeView1.getChildren();
for(i=0;i<NodeArray.length;i++)
{
cNode=NodeArray[i];
cNode.setAttribute("expanded","true");
//alert(cNode.getAttribute("Text"));
var cNodeArray=new Array();
cNodeArray=cNode.getChildren();
for(j=0;j<cNodeArray.length;j++)
{
var ccNode=cNodeArray[j];
ccNode.setAttribute("expanded","true");
}
}
}
在body属性中增加事件onload="ExpandOneTwo();"
树样式：SelectedStyle="background-color:gray;border:solid 1px black;" DefaultStyle="font-size:12px;font-family:verdana;"
树的Html代码如下：
1<iewc:TreeViewid="TreeView1"style="Z-INDEX:101;LEFT:320px;POSITION:absolute;TOP:160px"

别忘了在窗体的onload事件中调用ExpandOneTwo()函数
<bodyMS_POSITIONING="GridLayout"onload="ExpandOneTwo();">
