推荐答案

请参阅下面的CodeProject文章解决你的问题。 ToolTipListBox - 带有工具提示的列表框 [ ^ ]

Refer the below CodeProject article to resolve your problem. ToolTipListBox - a list box with tool tips[^]

AFAIK，这在ASP.NET中的下拉列表中是不可能的。您无法在鼠标悬停时打开/展开下拉列表。



此处有相关详细讨论：打开OnFocus活动的下拉列表？ [ ^ ]



如果你真的想要这样的行为，请在mouseover上尝试使用textbox和div下面的div。

AFAIK, this is not possible with dropdown in ASP.NET. You cannot open/expand the dropdown on mouseover.

A related detailed discussion here: Opening dropdownlist on OnFocus event?[^]

If you really want such behaviour, try with textbox and div below it on mouseover.

尝试下面的代码只需将这个java脚本添加到drop下来/选择



但要小心这个因为它可能会引起任何UI相关问题。







< asp：dropdownlist id =ddlPostClaimrunat =serveronmouseover =this.size = 5onmouseout =this.size = 1> ;

Try the code below just add this java script to the drop down/select

but be careful with this because it may rise u any UI related issues.



<asp:dropdownlist id="ddlPostClaim" runat="server" onmouseover="this.size=5" onmouseout="this.size=1">
