Pop up from UIP Application blocks

Question

I would like to open pop ups using UIP Application block logic. Can anyone help on that? Also, there are a few mroe queries regarding the UIP Block. Would appreciate help on the same. 1. I am trying to set certain properites in the Intialize() method by overriding the same in WebFormView. However, the control does not seem to go to the function at all, resulting in the code not being run. This, however, works in the case of Windows forms. Any help on how this can be achieved? 2. Can User Controls Navigator be used for Web applications? 3. Back button disabling does not seem to work in my application. Any step-by-step document on the same? 4. How to get the Navigate Value after navigating to a view. Eg: like CurrentView property. 5. pass query string thru UIP
