ASPX Avoid page refresh after selectedindexchanged combobox without updatepanel

Question

I am using a combobox on my website and when the SelectedIndexChanged event triggers, the page refreshes. I know you can prevent the page refresh with an UpdatePanel but I need another solution to prevent a page refresh.

Do you guys know any other solutions? Thanks in advance!

By your description in comments I think you want this. I´m using Jquery. This is a way to set value in textbox without to do postback. Remember to set AutoPostback=false in your DropDownList

<form id="form1" runat="server">
<asp:DropDownList ID="DropDownList1" runat="server">
    <asp:ListItem>Item 1</asp:ListItem>
    <asp:ListItem>Item 2</asp:ListItem>
    <asp:ListItem>Item 3</asp:ListItem>
    <asp:ListItem>Item 4</asp:ListItem>
</asp:DropDownList>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</form>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.10.4/jquery-ui.min.js"></script>
<script>
    var slcLocationSelect = false;
    var slcSpecialtySelect = false;
    var slcGenderSelect = false;
    $(document).ready(function () {
        $("#<%=DropDownList1.ClientID %>").change(function () {
            $("#<%=TextBox1.ClientID %>").val($("#<%=DropDownList1.ClientID %>").val())
        });
    });
</script>
