newbie in asp.net need help

Hi everyone,

I have a asp:listbox control. I want to have a javascript function that
detect the onselectedindexchanged and then make another textbox visible.
It just like the old fashion way in asp <select onchanged="myfunction()" >.
But with asp.net control i can't do that anymore on client-side

Please help ...Yes, you can.

myListBox.Attributes["onchanged"]="myfunction()";
