Question

When I try to open file picker on snap view in Metro Style App, exception occurs and exception dialog box was shown. How to solve that problem? Is there any good idea? I want my app works properly even on snap view.

Before opening the file picker, you must try to leave the snapped mode.

Here is the code I use:

var ready = true;
if (ApplicationView.Value == ApplicationViewState.Snapped)
    ready = ApplicationView.TryUnsnap();
if (!ready)
    return;
