you said you are adding it as an attribute..
if you are doing this..
DropDownList1.Attributes.Add("onchange","alert(2);return;");
make sure that you should not have the return status after your javascript
executes. remove the RETURN from above line.

asp.net spits out the html like this..
<select name="DropDownList1"
onchange="alert(2);return;__doPostBack('DropDownList1','')"..
so having return on onchange would not fire post back.
