aspx web form controls and client side java script

Hi all

Is it possible to handle web controls events on client side???

I wrote a simple favascript function inside the <header> area of an aspx
web form.
This function is called on selectedIndexChanged event of server side radio
button list,
but i can not get there . During compilation, it seems like the dotnet asp
service is looking for this function on that web form's (server side) code
behind instead
(this control's autoPostBack property is also set to false).
Am i right??

If so should i use regular html controls when i need to handle events on
client side?

I'm not sure i understand the advantage of using server side controls if
this is the case..

Assuming your DropDownList is ddl1, add this in your Page_Load():

ddl1.Attributes.Add("onchange", "myJavaScriptMethod(this)");

That'll do it for you.

Rea,
You don't need server controls in all cases. If you are populating the
combo box programmatically, then it'll need to be a server control. If not,
then just make it a regular html control and set onchange="myFunc(this);",
but if it's a server control, then follow Dale's suggestion. This puts that
onchange attribute there for you.

Best regards,
