How to disable right/left/up/down arrows hotkeys in flipview? I have a textbox on a flipview and when I move cursor using keyboard arrows and reach the end of textbox, it doesn't stop but flips the page which is annoying and is not applicable for my case. The same is true for cursor reaching the beginning of the textbox. I've tried different solutions, but none of them work.
<FlipView x:Name="flipView" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" IsTabStop="False">
<FlipView.Items>
<StackPanel>
<TextBox Text="AAAAA1"></TextBox>
<TextBox Text="AAAAA2"></TextBox>
</StackPanel>
<StackPanel>
<TextBox Text="BBBBB1"></TextBox>
<TextBox Text="BBBBB2"></TextBox>
</StackPanel>
<StackPanel>
<TextBox Text="CCCCC1"></TextBox>
<TextBox Text="CCCCC2"></TextBox>
</StackPanel>
</FlipView.Items>
</FlipView>
The trick is to handle KeyDown inside a custom FlipViewItem instead of FlipView itself.
So, you will first need to extend both classes.
public sealed class CustomFlipView : FlipView
{
public CustomFlipView()
{
this.DefaultStyleKey = typeof(CustomFlipView);
}
protected override DependencyObject GetContainerForItemOverride()
{
return new CustomFlipViewItem();
}
}
public sealed class CustomFlipViewItem : FlipViewItem
{
public CustomFlipViewItem()
{
this.DefaultStyleKey = typeof(CustomFlipViewItem);
}
protected override void OnKeyDown(KeyRoutedEventArgs e)
{
if (e.Key == VirtualKey.Left || e.Key == VirtualKey.Right || e.Key == VirtualKey.Up || e.Key == VirtualKey.Down)
{
e.Handled = true;
}
base.OnKeyDown(e);
}
}
Also don't forget to copy the default styles to Themes > Generic.xaml.

Here's a working demo. :)
One way to fix it is to filter them in KeyDown event of the each stackpanel.
