Hi,
1. I require to populate dropdowns and textboxes based on the selection
in one or the other dropdowns.
I tried to create a dropdown ,radiobutton,checkbox.
But I am not able to find the event handlers for the controls
mentioned.
(Like Onchange Event for dropdown list in .NET) .
It will be of great help, if I get some solution.
2 Also I require help in embedding different views (Html) into a
single main view with data from different tables (model) data.
Thanks in Advance

Hi,
1. You can easily do this with Prototype framework (http://
[prototypejs.org/](http://prototypejs.org/)) which is distributed with Rails or with even
standard javascript.
2. Not sure if I understand you but you might want to have look at
partials ([Peak Obsession](http://api.rubyonrails.com/classes/ActionView/)
Partials.html).
