Method not Found AJAX and javascript

[mnemukula]

I have a control that has a javascript method on it. I am adding attributes to a textbox. the attributes is the 'onkeyup" event and the method that should be executed. when i type something on the textbox, i have a javascript error stating that object requred. My control is hosted within another control that is placed on an update panel. what is strange is that i can see the javascriot method on the source code. Can anyone help?

Best Regards

We'll have a much better chance of figuring out the problem if you post your code. Make sure you post the client-side code as rendered in your browser (view source), not the server-side code.
