解决方案
您好，
您可以指定行的属性值（HTML大小），与列表中的实际选项元素（HTML select_control.length）的数量相同（ASP.NET Iterms.Count）。你也可以用Javascript来做。以下代码段显示了如何使用JavaScript在客户端完成。
< ！DOCTYPE html >
< html >
< script >
window .onload = function （）{
var lst = document .getElementById（' mylist'）;
lst.size = lst.length;
alert（lst.length）;
}
< / 脚本 >
< 正文 >
< 表格 >
< 选择 id = mylist >
< ; 选项 value < span class =code-keyword> = volvo > Volvo < / option >
< 选项 值 = saab > Saab < / option >
< 选项 value = opel > 欧宝< / option >
< 选项 value = audi > 奥迪< / option >
< 选项 value = 法拉利 > 法拉利< / option >
< span class =code-keyword>< 选项 value = swift > Swift < / option >
< 选项 value = etios > Etios < / option >
< / select >
< / form >
< / body >
< / html >

为我工作希望它能帮到你
<asp:ListBox ID="lboxCategory" runat="server" AutoPostBack="True" align="left" onselectedindexchanged="lboxCategory_SelectedIndexChanged" BackColor="#33CCFF" Height="100%" Width="100%"> </asp:ListBox>解决方案Hello,
You can specify the value for rows attribute (HTML size) same as the number of actual option elements (HTML select_control.length) in the list (ASP.NET Iterms.Count). You can also do it in Javascript. Following snippet shows how it can be done on client side using JavaScript.
<!DOCTYPE html> <html> <script> window.onload = function() { var lst = document.getElementById('mylist'); lst.size = lst.length; alert(lst.length); } </script> <body> <form> <select id="mylist"> <option value="volvo">Volvo</option> <option value="saab">Saab</option> <option value="opel">Opel</option> <option value="audi">Audi</option> <option value="ferrari">Ferrari</option> <option value="swift">Swift</option> <option value="etios">Etios</option> </select> </form> </body> </html>
