I'm in the process of developing a wp7 app as a side project at work. The form I'm creating really needs to be completed in order, for the most part.
I've added two screenshots, the first one is the initial screen, where a user enters the zone number. Once they dismiss the keyboard, there are some api calls made (with a loading indicator so users understand something is happening...) and the rest of the form pops up.
The second screenshot shows what happens after the api calls are finished... the user enters their space number, and selects the vehicle they want to park and then they press continue.
I know the menu needs to be changed around, and I'll do that soon enough. It right now allows them to go to settings, or see their active sessions.
My question is, how do I go about making it easier for users to get past the first step (dismissing the keyboard so the data call is made? At one point I was having a data call made every time they entered in a character into the "Zone Number" field, however, it became very complicated.
