我正在覆盖asp.net的TreeView控件的一些功能。我在树级视图中为1级或2级节点提供了一个css类。对于其余的节点，我不需要任何要分配的Css课程。我在Treeview课程中分配的＃con; con＆＃39;节点的css类是这样的：

我正在使用jquery在css类为＆＃39; con＆＃39;的节点上应用上下文菜单。但问题是当我选择任何节点时所有其他松散的css类。
<script type="text/javascript">
$(function () {
$.contextMenu({
selector: '#divLibraryTreeView .con',
callback: function (key, options) {
var m = "clicked: " + key;
window.console && console.log(m) || alert(m);
},
items: {
"edit": {
name: "Add group",
icon: "add",
callback: function () { document.getElementById('<%= imgbtnAddNewGroup.ClientID %>').click(); }
},
"cut": {
name: "Add task",
icon: "add",
callback: function () { document.getElementById('<%= imgbtnAddNew.ClientID %>').click(); }
},
"cancel": {
name: "Cancel",
icon: "cross",
callback: function () { return true; }
}
}
});
});
</script>
答案 0 :(得分：0)
答案很简单，只需要将cssclass添加到它自己的级别：
<LevelStyles>
<asp:TreeNodeStyle Font-Underline="False" />
<asp:TreeNodeStyle CssClass="con" Font-Underline="False" />
<asp:TreeNodeStyle CssClass="con" Font-Underline="False" />
</LevelStyles>
