I have some problem with a slider volume in my windows phone app 7.1
this is the XAML
<Slider Name="volumeSlider" VerticalAlignment="Center" ValueChanged="ChangeMediaVolume" Minimum="0" Maximum="1" Value="0.5" Margin="0,146,0,-27"/>
and this the simply function ChangeMediaVolume
private void ChangeMediaVolume(object sender, RoutedPropertyChangedEventArgs<double> args)
{
AudioPlayer.Volume = (double)volumeSlider.Value;
}
If I don't have this lines all it's ok... but when they are in the code the debugger show an error.
A first chance exception of type 'System.Windows.Markup.XamlParseException' occurred in System.Windows.ni.dll
If there is a handler for this exception, the program may be safely continued.
Probably this is what's wrong with it. Try changing the line
<Slider Name="volumeSlider" ...
to
<Slider x:Name="volumeSlider" ...
