Solution 1

after each entry, you can add the following:

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

you can also considering itemheight instead of adding blank line

Solution 2

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#

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

XML

<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>

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