Use this code-
.aspx code-
function show() {
var drp = document.getElementById('<%=DropDownList3.ClientID%>');
document.getElementById('<%=Label1.ClientID%>').innerHTML = drp.value;
alert(drp.value);
return false;
}
<asp:DropDownList ID="DropDownList3" runat="server">
<asp:ListItem>a</asp:ListItem>
<asp:ListItem>b</asp:ListItem>
<asp:ListItem>c</asp:ListItem>
</asp:DropDownList>
<asp:Label ID="Label1" runat="server"></asp:Label>
.cs code-
protected void Page_Load(object sender, EventArgs e)
{
DropDownList3.Attributes.Add("onchange", "return show();");
}
Try this and let me know.

you can set AutoPostBack property to false.
or you can make use <Select> <option>...</option> </select > Tags.
