推荐答案

每次输入后，你可以添加以下内容：



myListBox .Items.Insert（0，）;



您还可以考虑itemheight而不是添加空行

after each entry, you can add the following:

myListBox.Items.Insert(0, "");

you can also considering itemheight instead of adding blank line

而不添加您可以尝试应用css填充的任何空白项目[ ^ ]。检查以下答案，了解如何在asp.net中完成它＃

without adding any empty items you can try applying css padding[^] for listbox items. check below answers for how you can do it in asp.net c#

列表框呈现为在html中选择标签，所以使用css和javascript设置选项标签的高度属性，例如：

The listbox is being rendered as select tag in html, so set height property of the option tags using css and javascript, e.g.:

<form id="form1" runat="server">
    <asp:ListBox id="listbox1" rows="3" runat="server">
        <asp:ListItem selected="true">Item 1</asp:ListItem>
        <asp:ListItem>Item 2</asp:ListItem>
        <asp:ListItem>Item 3</asp:ListItem>
        <asp:ListItem>Item 4</asp:ListItem>
        <asp:ListItem>Item 5</asp:ListItem>
        <asp:ListItem>Item 6</asp:ListItem>
    </asp:ListBox>
</form>
<script>
    var options = document.getElementById("<%= listbox1.ClientID %>").options;
    for (i = 0; i < options.length; i++)

    {

        document.getElementById("listbox1").options[i].style.height = "25px";

    }

</script>

你可能想尝试不同的填充，边距等css属性

You may want to experiment with different css properties like padding, margin etc.
