Button within FlipView Click handler Frame->Navigate Exception

Question

Hey there,

I'm getting this odd exception: Within a standard LayoutAwarePage, I'm have a FlipView control that has a Button somewhere inside it. For the Click event, I have an event handler that uses Frame->Navigate() to navigate to a new page. Seems to work fine, until the handler is completed. After that I get an internal exception that I cannot debug. I'm not doing anything fancy either, just strictly navigating.

Event handler:

void MyPage::NewPageClick(Object^ sender, RoutedEventArgs^ e)
{

	TypeName pageType = { NewPage::typeid->FullName, TypeKind::Metadata };
	Frame->Navigate(pageType);

}

Page XAML:

<common:LayoutAwarePage
    x:Name="pageRoot"
    x:Class="TestApp.MyPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:TestApp"
    xmlns:common="using:TestApp.Common"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">
    <Grid>
    <FlipView>
        <FlipViewItem>
             <Grid>
                 <Button Content="New Page" HorizontalAlignment="Left" VerticalAlignment="Top" Click="NewPageClick"/>
             </Grid>
        </FlipViewItem>
        <FlipViewItem>
             <Grid />
        </FlipViewItem>
    <FlipView>

    </Grid>
</common:LayoutAwarePage>

Any ideas why this might be happening?

Hello,

As far as I know, we can use Selector.SelectedIndex property
http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.xaml.controls.primitives.selector.selectedindex
to navigate the FlipView control.

You can get the sample Flopview control sample codes from first,
http://code.msdn.microsoft.com/windowsapps/FlipView-Control-f9d9a99c

And then navigate the Flipview control through its name, like this
FlipView2Horizontal->SelectedIndex=1;

Best regards,

Jesse

Hey Jesse,

Thanks for your reply. However, that's not quite what I was looking for. Let me explain... I'm not trying to navigate the FlipView, but rather the Frame associated with MyPage to NewPage. If I pull the button out of the FlipView, the Page navigates without an exception. The caveat is when I do this with a Button inside a FlipViewItem, I get an exception. My guess is this has something to do with the FlipView or Frame control.

Cheers.

Hey Jesse,

I tried adding an UnhandledExceptionEventHandler to the App. I checked the message and it reads: "Call to UIASendMessageTimeout failed". Seems like a bug to me.

Cheers.

Hey,

Just an idea. Can it have something to do with this one? http://social.msdn.microsoft.com/Forums/en-US/winappswithcsharp/thread/f5b47c78-3660-43cf-b7e5-ab3aa9d173eb

As in the button event handler is attached couple of times and the btnClick function is over-executed.
