I'm getting started with WPF and trying to get my head around connecting data to the
UI. I've managed to connect to a class without any issues, but what I really want to do is connect to a property of the main window.
Here's the XAML:
<Window x:Class="test3.MainWindow"
xmlns="http://schemas.
microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.
microsoft.com/winfx/2006/xaml"
xmlns:custom="clr-namespace:test3"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<CollectionViewSource
Source="{Binding Source={x:Static Application.Current}, Path=Platforms}"
x:Key="platforms"/>
<DataTemplate DataType="{x:Type custom:Platform}">
<StackPanel>
<CheckBox IsChecked="{Binding Path=Selected}"/>
<TextBlock Text="{Binding Path=Name}"/>
</StackPanel>
</DataTemplate>
</Window.Resources>
<Grid>
<ListBox ItemsSource="{Binding Source={StaticResource platforms}}"/>
</Grid>
Here's the code for the main window:
public partial class MainWindow : Window
{
ObservableCollection<Platform> m_platforms;
public MainWindow()
{
m_platforms = new ObservableCollection<Platform>();
m_platforms.Add(new Platform("PC"));
InitializeComponent();
}
public ObservableCollection<Platform> Platforms
{
get { return m_platforms; }
set { m_platforms = value; }
}
}
Here's the Platform class:
public class Platform
{
private string m_name;
private bool m_selected;
public Platform(string name)
{
m_name = name;
m_selected = false;
}
public string Name
{
get { return m_name; }
set { m_name = value; }
}
public bool Selected
{
get { return m_selected; }
set { m_selected = value; }
}
}
This all compiles and runs fine but the list box displays with nothing in it. If I put a breakpoint on the get method of Platforms, it doesn't get called. I don't understand as Platforms is what the XAML should be connecting to!
