To keep things simple let's just say I have a c# Windows Store Project for Windows 8 that has the following items:
- GridView (PlatformsGrid)
- List«PlatformSearchResult» (allPlatforms)
- DataTemplate (PlatformDataTemplate) in standardstyles.xaml
allPlatforms is a collection of "PlatformSearchResult"objects populated from an online API, and has the following 3 properties:
- ID
- Name
- Alias
I am able to add a new item to the gridview for each object that exists in my allPlatforms collection, however the items are blank and do not show the data from my objects.
A quick summary of the current code looks like this:
XAML Markup:
<!-- Platforms Content -->
<GridView x:Name="PlatformsGrid" Grid.Row="1"
CanReorderItems="True" CanDragItems="True"
ItemTemplate="{StaticResource PlatformDataTemplate}" >
<GridView.ItemsPanel>
<ItemsPanelTemplate>
<WrapGrid MaximumRowsOrColumns="2"
VerticalChildrenAlignment="Top" HorizontalChildrenAlignment="Center" />
</ItemsPanelTemplate>
</GridView.ItemsPanel>
</GridView>
Data Template
<!-- Platform Item Template -->
<DataTemplate x:Key="PlatformDataTemplate">
<Grid Background="#FF939598" Height="250" Width="250">
<Image Source="/SampleImage.png" Stretch="UniformToFill"/>
<StackPanel Orientation="Vertical" Background="#CC000000"
Height="90" VerticalAlignment="Bottom">
<TextBlock Text="{Binding Name}"
Margin="10,3,0,0" Width="242" Height="62"
TextTrimming="WordEllipsis" TextWrapping="Wrap" HorizontalAlignment="Left"/>
<TextBlock Text="{Binding Alias}"
Margin="10,2,0,0" Width="186" Height="14"
TextTrimming="WordEllipsis" HorizontalAlignment="Left" FontSize="9" Opacity="0.49"/>
</StackPanel>
</Grid>
</DataTemplate>
Controlling Function
private async void FetchItemInfo_Loaded(object sender, RoutedEventArgs e)
{
// Get List of Top Games
List<PlatformSearchResult> allPlatforms = new List<PlatformSearchResult>();
allPlatforms = await GamesDB.GetPlatforms();
// Dynamically Create Platform Tiles
foreach (PlatformSearchResult platform in allPlatforms)
{
PlatformsGrid.DataContext = platform;
PlatformsGrid.Items.Add(platform);
}
}
How do I get the added items to show the appropriate object properties (ignoring the image for now), I'm just interested in populating the content of the TextBlocks.
I appreciate any help anyone can provide!
Thanks, Alex.
