System.OutOfMemoryException unhandled exception?

问题

I'm working on a C# project for windows phone 8 that plays selected youtube videos.My app has 1 page, which has 3 Grids (1 for each of 3 States).

1. Video Selection Menu (where I have an ItemsControl which has around 80-100 grids inside, where each of those grids has 2 textblocks, 1 image and a button inside them)
2. Video Details Menu (Shows more info about the video the user selected on the "Video Selection Menu" and has a play button which gets you to the third State).
3. Video (has a webbrowser control with the selected video)

Ok, about the problem now... When I have selected a video from State_1, then pressed play in State_2 that gets me to State_3 it's all ok. But when I go back to State_1 and start to scroll through the videos I get this exception: An unhandled exception of type 'System.OutOfMemoryException' occurred in System.Windows.ni.dll

Do you have any idea on what is the problem or how to fix this?

NOTE:

1. Whenever a State changes I make Visibility.Collapsed the 2 other Grids and Visibility.Visible the Grid that the State variable states.
2. When I don't have a webbrowser in the app (so no State_3) it works fine no problems. So my guess is that I need to disable the memory allocation of webbrowser when I'm not using it but not sure how.
