My app has a white background and a blue applicationBar on some pages. But everytime I tap the backbutton and leave a page the applicationBar goes down and leaves a black bar of the same size. At the same time all other elements disappear so I see most of the screen white and a black bar on the bottom for a second or so (slow device). Is there a way to avoid this?
I define my applicationBar in the xaml and on one page I switch two bars in the c#-code. nothing special.
I tried to remove it before leaving but it didn't help:
void PageBackKeyPress(object sender, System.ComponentModel.CancelEventArgs e)
{
ApplicationBar.IsVisible = false;
}
