Adding ajax/som event handler programmatically

[news.rz.uni-karlsruhe.de]

I wrote an event handler with
Sys.UI.DomEvent.addHandler($get("MyButton"),"click ",myfunc);

function myfunc(event)

{

alert("Hi!");

}

1.) If I write this code as a javascript block after the page under the
closing </htmltag everything works fine.

2.) If I write this code as a javascript block between the <headtags I get
an null pointer error from $get("MyButton").

3.) I get the same error if I use the ScriptManager.Scripts.Add(Reference),
obviously because the button "MyButton" doesn't exist yet.

So how can I add my event handler programmatically to achive the same
effect as in 1.)?

Howdy,

Leave the function declaration as it is, and paste this to Page_Load, or
Page_PreRender event handler:

string script = String.Format(
"Sys.UI.DomEvent.addHandler($get('{0}'),'click',my func);",
btn.ClientID);

ClientScript.RegisterStartupScript(this.GetType(), "whatever",
script, true);

Is there a possibility to have the
Sys.UI.DomEvent.addHandler($get('ButtonID'),'click ',myfunc) in a file as
well?
