asp:DropDownList

If I want to hang javascript off of an asp:DropDownList control, how would I
do this? There does not seem to be a "onchange" event so do I have to use
an HTML control to do this?

myDdl.Attributes["onchange"] = "myJavascriptFunction()";

If I remember well you have to put this code before Page_Load ... Page_Init
is one accepted place.

That is true for dynamically created controls. Dynamically created
attributes can be added in Page_Load.
