I am using a GridView ( and I even tried ListView for this purpose ) as a context indicator of my FlipView. The Problem is that when I try to tap/click on a gridViewItem in order for it to get selected and hence changing the flipviewItem index as well, the gridview is not recieving any tap or click interaction by the user to change it. However when I change flipviewItem from directly flipview, it works as expected and gridview item selected is also changed accordingly.
CODE
<Grid>
<FlipView x:Name="MainFlipView" ItemsSource="{x:Bind MyItemsSource}" Visibility="Visible"
SelectionChanged="FlipChanged">
<FlipView.ItemTemplate>
<DataTemplate x:DataType="data:Video">
<userControls:FlipDataTemplate />
</DataTemplate>
</FlipView.ItemTemplate>
</FlipView>
<GridView SelectionChanged="ContextChanged"
Name="ContextIndicator"
HorizontalAlignment="Right" VerticalAlignment="Bottom"
Margin="0,0,12,12"
ItemsSource="{x:Bind MyItemsSource}">
<GridView.ItemTemplate>
<DataTemplate x:DataType="data:Video">
<Image Width="40" Height="40" Source="{x:Bind Display}"/>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
</Grid>
C#
private void FlipChanged(object sender, SelectionChangedEventArgs e)
{
ContextIndicator.SelectedIndex = MainFlipView.SelectedIndex;
}
private void ContextChanged(object sender, SelectionChangedEventArgs e)
{
MainFlipView.SelectedIndex = ContextIndicator.SelectedIndex;
}
You need to set IsItemClickEnabled to True on your GridView.
I was able to solve it with help of #JustinXL and I put FlipView and GridView in Rows and made RowSpan of FlipView to 2 so I got same UI as I wanted but now it works as expected, apparently if they are in same row then FlipView interferes with UI interaction on GridView.
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<FlipView x:Name="MainFlipView" ItemsSource="{x:Bind MyItemsSource}" Visibility="Visible" Grid.RowSpan="2"
SelectionChanged="FlipChanged">
<FlipView.ItemTemplate>
<DataTemplate x:DataType="data:Video">
<userControls:FlipDataTemplate />
</DataTemplate>
</FlipView.ItemTemplate>
</FlipView>
<GridView SelectionChanged="ContextChanged" Grid.Row="1"
Name="ContextIndicator"
HorizontalAlignment="Right"
VerticalAlignment="Bottom"
Margin="0,0,12,8"
Canvas.ZIndex="1"
ItemsSource="{x:Bind MyItemsSource}">
<GridView.ItemTemplate>
<DataTemplate x:DataType="data:Video">
<Image Width="40" Height="40" Source="{x:Bind Display}"/>
</DataTemplate>
</GridView.ItemTemplate>
</GridView>
</Grid>
I'm trying to use a SemanticZoom in my Windows 8 application and it seems to not work.
Do I do something wrong here ?
I tried pretty much everything I thought that could work but in vain : removed the rowdefinitions, removed the style, removed the templates but still not working...
<Grid Style="{StaticResource LayoutRootStyle}">
<Grid.RowDefinitions>
<RowDefinition Height="140"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<SemanticZoom Grid.RowSpan="2">
<SemanticZoom.ZoomedInView>
<GridView x:Name="itemGridView"
AutomationProperties.AutomationId="ItemGridView"
AutomationProperties.Name="Grouped Items"
Padding="116,137,40,46"
ItemsSource="{Binding Source={StaticResource groupedItemsViewSource}}"
SelectionMode="None"
IsSwipeEnabled="True"
IsItemClickEnabled="True"

Thank you :)
If I understand your problem correctly, the semanticView in itself is working (you can zoom in and zoom out). But when you zoom back in the GridView items are the same and doesn't change according to the ZoomedOutView GridView item you selected.
But with your XAML I think this is normal behaviour, because when you select a category the binding on your gridview in zoomedInView doesn't change.
ItemsSource="{Binding Source={StaticResource groupedItemsViewSource}}"
My first advice would be to bind the ItemsSource to a list in your ViewModel not use a staticRessource.
Secondly you can change the SemanticView this way:
<SemanticZoom Grid.RowSpan="2" ViewChangeStarted="SemanticZoomChanged" >
And in your code behind add that:
private void SemanticZoomChanged(object sender, SemanticZoomViewChangedEventArgs e)
{
// First we check that we are going from ZoomedOut to ZoomedIn
if (e.IsSourceZoomedInView == false)
{
// I call a method in my ViewModel giving the chosen category in parameter
DefaultViewModel.OnSelectedCategoryChanged(e.SourceItem.Item.ToString());
}
}
Using MVVM I know it's ugly to have code in code-behind but this is not a lot and we are calling a method in the ViewModel to do the logic so it's still following MVVM design pattern.
And last we add a function in the ViewModel that will change the ItemsSource of the ZoomedInView
OnSelectedCategoryChanged(string chosenCategory)
{
// Here change the value of your groupedItemsViewSource list
GroupedItemsViewSource = ....;
}
Now it should work as you want to.
I have to add events in Controls which reides in ResourceDictionary ex. List SelectionChanged Image Tap etc, please suggest how cna i do this
Views-> MainPage.XAML
<Grid x:Name="LayoutRoot" Background="{StaticResource AppBackgroundColor}">
<phone:Panorama Name="Container" Grid.Row="0" ItemsSource="{Binding}" SelectionChanged="OnSelectionChanged" toolkit:TiltEffect.IsTiltEnabled="True"
Background="{StaticResource AppBackground}" TitleTemplate="{StaticResource AppPanoramaTitle}">
<phone:PanoramaItem Name="GetGalleryItem" Content="{Binding GetGalleryModel}" ContentTemplate="{StaticResource GetGalleryContent}"/>
</phone:Panorama>
Views->DataTemplates->GetGallery.XAML
<Image Source="{Binding THUMB, Converter = {StaticResource ThumbnailConverter}, ConverterParameter = 120}" Width="120" x:Name="testTap"
Height="120" Stretch="Fill" />
<Image Source="{Binding CategoryImage}" Width="130" Height="130" Stretch="Fill" />
</Grid>
</DataTemplate>
</controls:LongListSelectorEx.ItemTemplate>
</controls:LongListSelectorEx>
</DataTemplate>
For the tap event in your image, you could use the tap key work within your Image tag. such as
Xaml:
<Image Tap="tap_image" Source="{Binding THUMB, Converter = {StaticResource ThumbnailConverter}, ConverterParameter = 120}" Width="120" x:Name="testTap"
Height="120" Stretch="Fill" />
.cs
private void tap_image(object sender, System.Windows.Input.GestureEventArgs e)
{
//do whatever you wanted
}
Yes you could use the SelectionChanged event for a listbox or a longlistselector.
Have a look over here
Hope it helps
Default, they look like this: http://wp.qmatteoq.com/wp-content/uploads/2013/01/map.png. I would like to have them look like on Nokia Maps, like this: http://www.themobileindian.com/images/nnews/2012/11/9225/Nokia-Maps.jpg, so they take less space. And everytime I tap on them, they will toggle between icon and description.
Lets say I have two templates for pushpin in resources:
<ControlTemplate x:Key="1" TargetType="maptk:Pushpin">
<Grid x:Name="ContentGrid" Background="Transparent" Margin="-4,0,0,0">
<StackPanel >
<Grid Background="Black">
<StackPanel Margin="5,5,0,0">
<i:Interaction.Triggers>
<i:EventTrigger EventName="Tap">
<cmd:EventToCommand PassEventArgsToCommand="False"
CommandParameter="{Binding}"
Command="{Binding ElementName=NearbyMap, Path=DataContext.Pushpin_OnTapCommand}"/>
</i:EventTrigger>
</i:Interaction.Triggers>
<TextBlock Text="{Binding Location}" Foreground="White" />
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding LocationName}" Foreground="White" />
<TextBlock Text="-" Foreground="White" Padding="3,0"/>
<TextBlock Text="{Binding LocationName}" Foreground="White" />
</StackPanel>
<TextBlock Text="{Binding LocationName}" Foreground="White" />
<TextBlock Text="{Binding LocationName}" Foreground="White" />
</StackPanel>
</Grid>
<Polygon Fill="Black" Points="0,0 29,0 0,29" Width="29" Height="29" HorizontalAlignment="Left" />
<Grid Height="26" Width="26" Margin="-13,-13,0,0" RenderTransformOrigin="0.5,0.5" HorizontalAlignment="Left">
<Grid.RenderTransform>
<CompositeTransform Rotation="-45"/>
</Grid.RenderTransform>
<Rectangle Fill="Black" HorizontalAlignment="Center" Margin="0" Stroke="White" VerticalAlignment="Center" Height="26" Width="26" />
<Ellipse HorizontalAlignment="Center" Height="16" Margin="0" VerticalAlignment="Center" Fill="Green" Width="16" />
</Grid>
</StackPanel>
</Grid>
</ControlTemplate>
<ControlTemplate TargetType="maptk:Pushpin" x:Key="2">
<Grid Height="26" Width="26" Margin="-13,-13,0,0" RenderTransformOrigin="0.5,0.5" >
<Grid.RenderTransform>
<CompositeTransform Rotation="-45"/>
</Grid.RenderTransform>
<Rectangle Fill="Black" HorizontalAlignment="Center" Margin="0" Stroke="White" VerticalAlignment="Center" Height="26" Width="26"/>
<Ellipse HorizontalAlignment="Center" Height="16" Margin="0" VerticalAlignment="Center" Fill="Red" Width="16"/>
</Grid>
</ControlTemplate>
and the pushpin control:
<maptk:Pushpin x:Name="PushPins" GeoCoordinate="{Binding Location}" Visibility="Visible" Content="{Binding LocationName}" Template="{StaticResource 2}"/>
How can I switch between them with some triggers or something?
#Rares found another solution, that works great in my case...
So the general issue here is just, how to switch/change the design when tapping the pushpin.
Well it seems that when you add the pushpins to the map they get their design from the toolkit, but you still are able to change that by setting the Style propery in code!
So if you hook up each pushpin to a pushpin tap event you can just do the following in your code behind of the XAML page:
private void Pushpin_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
((Pushpin)sender).Style = Application.Current.Resources["PushpinStyle"] as Style;
}
Provided you created a PushpinStyle inside a resourcedictionary that has a Pushpin as TargetType.
To be able to reset the design when pushing on another pushpin, I just keep a reference to the pushpin pressed and reset it's style before changing the style of the newly pressed one!
Works great for me...
You can use a general trick to modify the look of TK components. This can be used for nearly all TK components.
All TK components have styles (defined in XAML), these are not settable via code. But you can override the style in your applicatoin (keep in mind, you override the style in general, so if you modify e.g. pushpin styles, all pushpins inside your app will look like that)
A bit more in detail:
a) Get the TK source from https://phone.codeplex.com/sourcecontrol/latest
b) Have a look into Themes/Generic.xaml
c) Next to the last element, you see the style definition for the pushpin.
Starts with:
<!-- Default Style used for Pushpin -->
<Style TargetType="maptk:Pushpin">
...
d) Copy this style (or you can write it from scratch of course) and modify the style to whatever you like
e) Add this modified code snippet to your Application.Resources (e..g. the Application.Resources section in your App.xaml)
Keep in mind, you also need to reference the right TK namespace.
For pushpin, you need to include:
xmlns:maptk="clr-namespace:Microsoft.Phone.Maps.Toolkit"
Now your app uses the locally overriden style for your pushpin.
Btw: Since TK is Ms-PL licensed, keep in mind that there are probably license restrictions if you take the original source code from MSFT.
I personally found it easier to not use the toolkit for pushpins. Instead I wrote a user control "PushPinUC" that I designed how I wanted it. The UserControl subscribes to the Tap event - so I can expand/retract when it's pressed.
You can add user controls to your Map control using the following code.
private void BindPushpins(IEnumerable<PushpinIVM> pushpins)
{
foreach (var pushpin in pushpins)
{
var pushPinUC = new PushpinUC { Pushpin = pushpin };
var mapOverlay = new MapOverlay { GeoCoordinate = pushpin.Location, Content = pushPinUC };
var mapLayer = new MapLayer { mapOverlay };
Map.Layers.Add(mapLayer);
}
}
I found a solution: add only one control template to the pushpins. The stackpanel is the pushpin with the textbox and the grid before the stackpanel is the pushpin without the textbox. The stackpanel is with visibility collapsed. As you can see there are 2 triggers for the tap event, where i just set the visibility of the pushpin with the textbox to visible or collapsed. You can use any image for the pushpins.

#Depechie
private void RectangleTapAction(GestureEventArgs e)
{
var pushpinControl = TryFindParent<Pushpin>(e.OriginalSource as UIElement);
var pushpin = (pushpinControl as FrameworkElement).DataContext as PushPinModel;
Locations.Where(t => t.Id != pushpin.Id).ToList().ForEach(t => t.Visibility = Visibility.Collapsed);
pushpin.Visibility = pushpin.Visibility == Visibility.Visible ? Visibility.Collapsed : Visibility.Visible;
e.Handled = true;
}
Locations is an ObservableCollection and there is a Linq where I hide the textbox for other pushpins. PushPinModel has an attribute representing the visibility.
When I call Page.Frame.Navigate is i possible to navigate to a page smaller than screen size and make it lay over the page i just navigated from in any simple way? The ideal solution would not involve a large framework and the need to rewrite large parts of the application. I am looking for this effect: Windows 8 Music App
I guess I could make a hack by passing a snapshot of the page being navigated from to the new page and using this as a backdrop but I would prefer a cleaner solution. I guess I also could access the navigation stack from the new page and render the old behind.
You could use the Popup element, as William Melani stated. Here's an example:
<Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
<Grid.RowDefinitions>
<RowDefinition Height="1*"></RowDefinition>
<RowDefinition Height="2*"></RowDefinition>
</Grid.RowDefinitions>
<Button x:Name="btnPopup" Content="Open Popup" Click="btnPopup_Click_1" Grid.Row="0"></Button>
<Popup IsLightDismissEnabled="True" x:Name="popup1" Grid.Row="1" HorizontalAlignment="Center">
<StackPanel Background="Black">
<Border Background="Blue" BorderThickness="2">
<StackPanel>
<StackPanel Orientation="Vertical" Margin="10">
<TextBlock Text="User:" VerticalAlignment="Center" Margin="0,0,10,0" FontSize="20" />
<TextBox Height="40" Width="250" FontSize="20" />
<TextBlock Text="Mail:" VerticalAlignment="Center" Margin="0,0,10,0" FontSize="20" />
<TextBox Height="40" Width="250" FontSize="20" />
</StackPanel>
<Button HorizontalAlignment="Right" Margin="10">Accept</Button>
</StackPanel>
</Border>
</StackPanel>
</Popup>
And the button event:
private void btnPopup_Click_1(object sender, RoutedEventArgs e)
{
popup1.IsOpen = true;
}
Design isn't really my thing.
