Show/Hide Specific ListView Items

Question

I have a pretty standard listview that looks like this:

<ListView x:Name="itemListView"
    AutomationProperties.AutomationId="ItemListView"
    AutomationProperties.Name="Grouped Items"
    ItemsSource="{Binding Source={StaticResource groupedItemsViewSource}}"
    ItemTemplate={StaticResource Standard80ItemTemplate}"
    IsItemClickEnabled="True"
    PointerReleased="itemListView_PointerReleased_1">
    <ListView.GroupStyle>
        <GroupStyle>
            <GroupStyle.HeaderTemplate>
                <DataTemplate>
                    <Grid x:Name="MyItems">
                        <StackPanel Orientation="Vertical">
                            <StackPanel x:Name="Header">
                                ....
                            </StackPanel>
                            <Grid x:Name="Details" Visibility="Collapsed">
                                ....
                            </Grid>
                         </StackPanel>
                      ....

I'm basically displaying a list of items, and each item consists of 2 parts; a header and a grid of item details. I'm hiding all item details by default and only displaying the headers for users to click. I want to show the details of whichever item header is clicked in the following handler:

void itemListView_PointerReleased_1(Platform::Object^ sender, Windows::UI::Xaml::Input::PointerRoutedEventArgs^ e)
{
    // Hide all item details
    // Show details of the item we just clicked
}

This is where I'm currently stuck; how would I get from Object^ sender to the UIElement I want to show/hide?

Hello,

 

I think you can try to use PopInThemeAnimation and PopOutThemeAnimation. You can follow this document

Best regards,

Jesse

Hi Inspira,

You could have a Dependency Property bound to the "Visibility" of the ListItem template and then manipulate it by using the SelectedItem in the EventArgs.  

Answer 3

can you give me an example to do this? I also met the same problem on how to show/hide the ListView item.

thanks!
