Thanks a lot, it worked great.
I have one more question. I have to create same panel multiple times , based
on user output into the form and i have list of panel data model object
inside my form data object. Is it better to generate panels in page class
and then passed list of panels into form constructor and use ListView or
generate it inside form with RepeatingView and create new instance of
PanelData in Cycle and setting it on Panel and saving it to list like
this...
RepeatingView rp = new RepeatingView();
for(int i =0; i< n; i++){
WebMarkupContainer parent = new WebMarkupContainer(rp.newChildID());
}
