Динамическое создание GridView из ObservableCollection ⇐ C#

[Anonymous]

В моем приложении C#/WPF у меня есть

Код: Выделить всё

ListView

that I want to use as a

Код: Выделить всё

GridView

to display items in a table:

Код: Выделить всё

It is binded to a

Код: Выделить всё

ObservableCollection

, where

Код: Выделить всё

Condition

is defined like this:

Код: Выделить всё

public class Condition
{
public string Name { get; set; }
public ObservableCollection Properties { get; set; }

public class Property
{
public string Name { get; set; }
public double Value { get; set; }
}
}

(Please note that I skipped

Код: Выделить всё

INotifyPropertyChanged

implementation here to simplify this example code).
Idea is that GridView Column headers should display

Код: Выделить всё

Name

property of instances of

Код: Выделить всё

Condition

, while row headers should display

Код: Выделить всё

Name

instance of Property, and the cells - the

Код: Выделить всё

Value

. It is expected that all

Код: Выделить всё

Condition

instances will have the same number of Property instances with the same names. So for example if we have this method that creates sample data:

Код: Выделить всё

private ObservableCollection CreateConditions()
{
ObservableCollection conditions = new();

conditions.Add(
new Condition()
{
Name = "c1",
Properties = new()
{
new() { Name = "p1", Value = 5 },
new() { Name = "p2", Value = 10 },
new() { Name = "p3", Value = 15 },
}
});

conditions.Add(
new Condition()
{
Name = "c2",
Properties = new()
{
new() { Name = "p1", Value = 8 },
new() { Name = "p2", Value = 12 },
new() { Name = "p3", Value = 20 },
}
});

conditions.Add(
new Condition()
{
Name = "c3",
Properties = new()
{
new() { Name = "p1", Value = 11 },
new() { Name = "p2", Value = 17 },
new() { Name = "p3", Value = 25 },
}
});

return conditions;
}

Then the GridView table should look like this:

Код: Выделить всё

-   c1  c2  c3
p1  5   8   11
p2  10  12  17
p3  15  20  25

Since I'm trying to use MVVM, the view model looks like this:

Код: Выделить всё

public class TableResultsViewViewModel
{
public ObservableCollection Conditions { get; set; }

public TableResultsViewViewModel(ObservableCollection conditions)
{
this.Conditions = conditions;
}
}

And the main class:

Код: Выделить всё

public partial class MainWindow : Window
{
private TableResultsViewViewModel vm;

public MainWindow()
{
InitializeComponent();
ObservableCollection conditions = CreateConditions(); //sample data creation method from before
vm = new TableResultsViewViewModel(conditions);
this.DataContext = vm;
}
}

But I can't figure out how to properly declare the ListView in WPF so that it would dynamically generate these columns and rows as the

Код: Выделить всё

ObservableCollection Conditions

changes (instances of

Код: Выделить всё

Condition

added or removed from this collection, or instances of

Код: Выделить всё

Property

added or removed from

Код: Выделить всё

Properties

list inside the instances of

Код: Выделить всё

Condition

). Has anyone done anything similar and could help me out?
