C# control event handling with javascript

Question

How can I get javascript to execute for "onchange" / "OnSelectedIndexChanged" event instead of a CodeBehind method? I think "OnSelectedIndexChanged" event has to be handled by CodeBehind; but how can I replace that (or onchange) with a javascript event handler?

I have the following in my xyz.ascx file:

<asp:DropDownList ID="ddlTypeCar" CssClass="BatsRefAddressTypes" runat="server"
                  onchange="javascript: testAlert();"
                  OnSelectedIndexChanged="ddlTypeCar_SelectedIndexChanged"
                  AutoPostBack="True" />

I could not get the javascript to execute, even though I removed OnSelectedIndexChanged="ddlTypeCar_SelectedIndexChanged" and/or set AutoPostBack="false".

Additionally, I tried added the following in xyz.ascx.cs Page_Load() method.

ddlTypeOfAddress.Attributes.Add("onchange", "javascript: testAlert();");

which didn't help.

Thanks for your help in advance.
