什么数控件比较快???????????

用Java脚本不行，我强烈建议你使用ajax下的速度绝对快，里面尽量不要用FOR循环（太占资源）几十万的数据肯定出不来。

采用ajax,用到哪里加载到哪里..

下一个ajax 框架，可以实现你要的功能！！AjaxPro.dll 这个很不错

用prototype框架,但是进行分布式加载

使用ajaxpro给你个代码<body onclick="var popmenu=document.getElementById('contextmenu');popmenu.style.display='none';"
onload="createFirst()" MS_POSITIONING="GridLayout">
<form name="Form1" method="post" action="equipmentAjaxTree.aspx" id="Form1">
<input type="hidden" name="__VIEWSTATE" value="dDwtMTI3OTMzNDM4NDs7PhxHeluQe4tD9SFJah31QU4fwaxl" />
