Component development question about controller/view?

[jomlary]

Hi,

i develop at the moment my first component, already i have 2 views, in the first view i read all categories and in the second all products, this was very easy to do but my question is:

I added a new view named "export", in this view i added a small form with submit button and 2 radiobuttons (export categories, export products), my question is, for a export for one of this 2 things is needed to develop in controller, right? If yes, how can i tell form in the view if user select a radiobutton option and submit form that he get result from my controller?

Thanke you in advance.

you have 2 radiobutton, when select one you can get one report......
you need to have one form.... after click submit, you can call the view that you defined before. you can use javascript to call the view that you want. example: click button event()
