<style type="text/css">
.panel { display:none }

</style>

<div style="padding-top:20px;padding-left:10px;border:solid 1px #CCC">
<input type="button" id="btn1" title="1" value="Button1" onmouseover="btn_over(this);" onmouseout="btn_out(this);" />&nbsp;&nbsp;&nbsp;
<input type="button" id="btn2" title="2" value="Button2" onmouseover="btn_over(this);" onmouseout="btn_out(this);"; />
<div>
<asp:Panel ID="panel1" runat="server" CssClass="panel" > aaaaaa</asp:Panel>&nbsp;&nbsp;&nbsp;
<asp:Panel ID="panel2" runat="server" CssClass="panel" >bbbb</asp:Panel>
</div>
</div>
</form>
<script type="text/javascript">
function btn_over(obj)
{
var s=obj.title;
document.getElementById("panel"+s).style.display="block";
}
function btn_out(obj)
{
var s=obj.title;
document.getElementById("panel"+s).style.display="none";
}

</script>
------解决方案--------------------
在button1上 加上 onmouseover= "PanelN.Visible = 'true'"
onmouseout = "PanelN.Visible = 'false'"
看看效果吧

------解决方案--------------------
更正:
<div>
<asp:Panel ID="panel1" runat="server" > aaaaaa</asp:Panel>&nbsp;&nbsp;&nbsp;
<asp:Panel ID="panel2" runat="server" CssClass="panel" >bbbb</asp:Panel>
</div>
