databinding of object property in dictionary

I have question about databinding in XAML. I have dictionary in which are my objects. Now in the view I want show in first listbox key of dictionary (with this no problem), but in nested listbox show values of that object.
So - my code in XAML:
<ListBox ItemsSource="{Binding Dict}" Margin="0,0,171,0">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Path=Key}" />
<ListBox ItemsSource="{Binding Path=Value}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Path=Key}" />
<TextBlock Text="{Binding Path=Value}" /> <!-- HERE -->
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
following with code from ViewModel:
public MainWindow()
{
InitializeComponent();
t = new TestModel();
t._dict = new Dictionary<string, Dictionary<string, myDrive>>();
t._dict.Add("folder1", new Dictionary<string, myDrive>());
t._dict["folder1"].Add("file1", new myDrive() { size = "71" });
t._dict.Add("folder2", new Dictionary<string, test>());
t._dict["folder2"].Add("file1", new myDrive() { size = "54" });
t._dict["folder2"].Add("file2", new myDrive() { size = "30" });
this.DataContext = t;
}
and code from model:
public Dictionary<string, Dictionary<string, myDrive>> _dict;
public Dictionary<string, Dictionary<string, myDrive>> Dict
{
get
{
return this._dict;
}
}
and class myDrive is simple:
public class myDrive
{
public string size = "";
public string getSize()
{
return this.size;
}
}
My goal is show parameter size in that textbox so I tried different ways like:
<TextBlock Text="{Binding Path=Value.size}" />
<TextBlock Text="{Binding Path=Value[size]}" />
<TextBlock Text="{Binding Path=Value.getSize}" />
but no luck :(. Only if I put Value like in example, than can see output string : "AppName.myDrive".
Thanks for any help

First define property for size variable. You can only Databind properties not variables.
public class myDrive
{
public string size = "";
public string Size{get{return size;}}
public string getSize()
{
return this.size;
}
}
Once this is done, you can bind like below
<ListBox ItemsSource="{Binding Dict}" Margin="0,0,171,0">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Path=Key}" />
<ListBox ItemsSource="{Binding Path=Value}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Path=Key}" />
<TextBlock Text="{Binding Path=Value.Size}" />
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

Bind a textblock in a nested list member

I have these classes:
public class Datum
{
public string name{get;set;}
public string id{get;set}
public List<Brewery> breweries { get; set; }
.
.
}
public class Brewery
{
public string name { get; set; }
.
.
}
And this Listbox
<ListBox ItemsSource="{Binding}" HorizontalAlignment="Left" Height="580" Margin="0,80,0,0" VerticalAlignment="Top" Width="446">
<ListBox.ItemTemplate>
<DataTemplate>
<ListBoxItem Tap="ListBoxItem_Tap" Tag="{Binding Path=id}">
<TextBlock Name="First" Text="{Binding Path=name}" />
<TextBlock Name="Second" Foreground="Gray" Text="{Binding Path=breweries.name}" />
</ListBoxItem>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
So I create a list of Datum objects and I bind the listbox to it. In that way, the First textblock is bound to the property 'name' of the Datum class.That works perfectly. What I want is the Second textblock to be bound to the property 'name', of the first item of the Brewery list.
If breweries was not a List I would easily do that, but since I take the info from a json, I can't change that.

From your example, if I understand what you're doing correctly, you should just be able to use an index to bind to the desired item from the collection. I'm not sure it's the best approach, but it should yield the result you're after.
E.g. (adapting your example):
<ListBox ItemsSource="{Binding}" HorizontalAlignment="Left" Height="580" Margin="0,80,0,0" VerticalAlignment="Top" Width="446">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<ListBoxItem Tap="ListBoxItem_Tap" Tag="{Binding Path=id}">
<TextBlock Name="First" Text="{Binding Path=name}" />
<TextBlock Name="Second" Foreground="Gray" Text="{Binding Path=breweries[0].name}" />
</StackPanel>
</ListBoxItem>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>

Nested Listbox wont display nested list

<ListBox Height="434" HorizontalAlignment="Left" Margin="6,238,0,0" Name="listBox1" VerticalAlignment="Top" Width="432" DataContext="{Binding}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Name}" Margin="4" Foreground="{StaticResource PhoneAccentBrush}"></TextBlock>
<StackPanel Orientation="Horizontal" Margin="4">
<TextBlock Text="Set" Margin="16" Foreground="{StaticResource PhoneAccentBrush}" />
<TextBlock Text="Weight" Margin="16" Foreground="{StaticResource PhoneAccentBrush}" />
<TextBlock Text="Reps" Margin="10,16,0,16" Foreground="{StaticResource PhoneAccentBrush}" />
</StackPanel>
<ListBox Name="setsAndReps" Height="auto" Width="auto" ItemsSource="{Binding Sets}">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<TextBox Text="{Binding SetNumber}"/>
<TextBox Text="{Binding Weight}"/>
<TextBox Text="{Binding Reps}"/>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
The outer listbox's item source is being set to an observable collection of a user defined class called excercise
public class excercise : IComparable, IEquatable<excercise>, INotifyPropertyChanged
{
string name;
int max;
int NUM_SETS;
ObservableCollection<set> sets;
public event PropertyChangedEventHandler PropertyChanged;
public string Name
{
get { return this.name; }
set { this.name = value; }
}
public excercise(string name)
{
this.name = name;
this.NUM_SETS = 0;
this.sets = new ObservableCollection<set>();
}
public ObservableCollection<set> Sets
{
get{return this.sets; }
}
public ObservableCollection<set> getSets()
{
return this.sets;
}
}
The properties in the inner list box are from the set class but none of them are being displayed and I am not sure what the problem is.

your first listbox doesn't have any itemsource set and the datacontext is set to an empty binding (both on line 1 of your code)

Data Binding Help - WPF

I have those two classes:
class DownloadLink
{
public string Name { get; private set; }
public string Url { get; private set; }
//(...)
}
class DownloadGroup
{
public List<DownloadLink> Links { get; private set; }
//(...)
}
class Manager
{
public List<DownloadGroup> Groups { get; private set; }
}
Manager managerOBJ = new Manager();
I want to display this like that:
Everything will be in ListBox:
I wan to bind managerOBJ.Groups to that ListBox. - How to do it?
Than I want to create DataTamplate to display each group and all links in that group. - How to do it?
I want to do as much as possible from XAML
UPDATE:
This is what I got. It's not workig. List box is empty.
<ListBox DockPanel.Dock="Right" VerticalAlignment="Stretch" Width="500" HorizontalAlignment="Right" Background="#FFE1FFF5" HorizontalContentAlignment="Stretch" ScrollViewer.HorizontalScrollBarVisibility="Disabled" ScrollViewer.VerticalScrollBarVisibility="Visible" ItemsSource="{Binding Path=Groups}" Name="GroupsListBox">
<ListBox.ItemTemplate>
<DataTemplate>
<StackPanel Height="30" VerticalAlignment="Top" Width="500" >
<Grid Height="Auto" Width="500">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Label Content="XX MB w XX plikach" HorizontalAlignment="Stretch" Margin="0"/>
</Grid>
<ListBox HorizontalAlignment="Stretch" Height="43" Margin="0,5,0,0" Width="Auto" VerticalAlignment="Top" ItemsSource="{Binding Path=Links}">
<ListBox.ItemTemplate>
<DataTemplate>
<Label Content="{Binding Path=Name}" />
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
and in code behid I have:
RapideoAccount = new Rapideo();
GroupsListBox.DataContext = RapideoAccount;

The whole manager is contained in a listbox, for each downloadgroup in the manager you add an itemscontrol that contains another items control with the links in it.
This can be done by using DataTemplates:
<ListBox Name="myGroups"
ItemsSource="{Binding Path=Groups}">
<!-- each List<DownloadGroup> in the manager: -->
<ListBox.ItemTemplate>
<DataTemplate>
<ItemsControl ItemsSource="{Binding Path=Links}">
<!-- each Link in the Downloadgroup -->
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel>
<TextBlock Text="{Binding Path=Name}" />
<TextBlock Text="{Binding Path=Url}" />
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
In code you would put:
Manager managerOBJ = new Manager();
myGroups.DataContext = managerOBJ;

define managerOBJ as a property in your viewmodel
binding viewmodel to your view.
binding ListBox itemssource to managerOBJ.Groups.
define DataTemplate inside ListBox to display each DownloadGroup.

Can't cast treeviewitem as treeviewitem in wpf

I've got webservice asmx, and there are classes:
Country
public string Name {get;set;}
public string Code {get;set;}
public List<Area> Areas {get;set;}
Area
public string Name {get;set;}
public string Code {get;set;}
public List<Regions> Provinces {get;set;}
Provinces
public string Name {get;set;}
public string Code {get;set;}
I bind it to mz TreeView WPF:
Country[] items = new MyService().GetListOfCountries();
structureTree.ItemsSource = items;
Code of myTree:
<UserControl x:Class="ObjectsAndZonesSimpleTree"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
<Grid>
<StackPanel Name="stackPanel1">
<GroupBox Header="Choose" Height="354" Name="groupBox1" Width="Auto">
<TreeView Name="structureTree" SelectedItemChanged="structureTree_SelectedItemChanged" Grid.Row="0" Grid.Column="0" ItemsSource="{Binding}" Height="334" ScrollViewer.VerticalScrollBarVisibility="Visible" ScrollViewer.HorizontalScrollBarVisibility="Visible" Width="Auto" PreviewMouseRightButtonUp="structureTree_PreviewMouseRightButtonUp" FontFamily="Verdana" FontSize="12" BorderThickness="1" MinHeight="0" Padding="1" Cursor="Hand" Margin="-1">
<TreeView.Resources>
<HierarchicalDataTemplate DataType="{x:Type MyService:Country}"
ItemsSource="{Binding Path=ListOfRegions}">
<StackPanel Orientation="Horizontal">
<TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text="{Binding Path=Name}"/>
</StackPanel>
</HierarchicalDataTemplate>
<HierarchicalDataTemplate DataType="{x:Type MyService:Region}"
ItemsSource="{Binding Path=Provinces}">
<StackPanel Orientation="Horizontal">
<TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text="{Binding Path=Name}"/>
</StackPanel>
</HierarchicalDataTemplate>
<DataTemplate DataType="{x:Type MyService:Province}"
ItemsSource="{Binding Path=ListOfCities}">
<StackPanel Orientation="Horizontal">
<TextBlock TextAlignment="Justify" VerticalAlignment="Center" Text="{Binding Path=Name}"/>
</StackPanel>
</DataTemplate>
</TreeView.Resources>
</TreeView>
</GroupBox>
</StackPanel>
</Grid>
</UserControl>
This gives me null:
private void structureTree_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e)
{
TreeViewItem treeViewItem = structureTree.SelectedItem as TreeViewItem;
}

SelectedItem will actually contain a Country, Area, or Region (or null). If you really want the TreeViewItem, you can do strutureTree.ItemContainerGenerator.ContainerFromItem(structureTree.SelectedItem).

Correct. You should expect a Country as your SelectedItem. WPF works entirely different than Windows Forms did. It's all about databinding!
