Strange bug!! A simple ListPicker doesn't show it's items when I click it!! What?!?!?!?

Question

Hi guys. I have a bug in my application and I çan't imagine what I could possibly been doing wrong. I have 2 listPickers in my app. If I press one of them, I get the list of regions but if I press the town list picker ("pueblo" in spanish) it dosn't take me to the screen that suppose to show me the towns. I'm doing exactly the same thing with both of them. I already debugged the app and the the listpcker's items sources HAVE the information. I'm not an expert but definitely not a noob either so this whole thing is just fu$#% up or I'm really missing a stupid thing. I uploaded the entire solution in a .zip file if you guys want to check it out. I will waiting for your answers.

Thank you all!

Hello Samuel! Welcome to C# Corner. I think people are reluctant to download source code to look at a problem. I think it is mainly the problem of looking at a large amount of code. Also if this is a Windows Phone application that we need the Windows Phone SDK to look at the application then that limits the number of people that can help. My guess is that there is a simple explanation; something so simple that it is easy to overlook. Do you know how to use the debugger? Do you know how to single-step through the code? You can single-step through the code to watch what is happening when you put data into the control. You can verify that that is working at least. A common beginner mistake is to use multiple instances of forms or controls. You might be adding data to the control but the control that you see in the form might be a different instance.
