如何以编程方式将WPF Datagrid绑定到自定义对象的ObservableCollection？

Question

I've been searching for ages and haven't found any solution. Title basically covers what I'm trying to accomplish. Here's what I have so far that clearly isn't working with irrelevant stuff cut out.

In MainWindow.xaml.cs:

public MainWindow()
{
    InitializeComponent();

    ModGrid = new DataGrid();
    ModGrid.CanUserReorderColumns = false;

    DataGridTextColumn Name = new DataGridTextColumn();
    Name.Header = "Name";
    Name.MinWidth = 45;
    Name.Width = (DataGridLength)(new DataGridLengthConverter()).ConvertFromString("*");
    Binding nameBinding = new Binding("Name");
    nameBinding.Mode = BindingMode.OneWay;
    Name.Binding = nameBinding;
    ModGrid.Columns.Add(Name);

    DataGridTextColumn Tags = new DataGridTextColumn();
    Tags.Header = "Tags";
    Tags.MinWidth = 40;
    Tags.Width = 200;
    Binding tagsBinding = new Binding("Tags");
    tagsBinding.Mode = BindingMode.OneWay;
    Tags.Binding = tagsBinding;
    ModGrid.Columns.Add(Tags);

    // There are more columns but you get the idea

    ModGrid.ItemsSource = Database.Mods;
}

private void RibbonWindow_Loaded(object sender, RoutedEventArgs e)
{
    ModGrid.DataContext = Database.Mods;
}

Later I add items to Database.Mods

void Fetcher_RequestComplete(bool error, string result, int requestsLeft)
{
    if (!error)
    {
        Database.Mods = Parser.ParseMods(result);
    }
}

This is all that's in database.cs

public static class Database
{
    public static ObservableCollection<Mod> Mods = new ObservableCollection<Mod>();
}

And this is all that's in mod.cs

public class Mod
{
    public Mod() { }

    public Image Status;
    public string Name;
    public string Description;
    public string Author;
    public string Tags;
    public int Views;
    public string Link;
    public string[] Versions;
    public string[] TagsList;
}

Sorry about the code spam but I haven't seen how to do this entirely programmatically and it's necessary that I do. Any responses at all are very appreciated!

Edit:

While I did find an answer, if your in this situation I've found it would be much better to just make a custom control and have access from the XAML that way.

Answer 1

EDIT: your question is a little bit wrong because you do not BIND something to your grid you simply SET the itemssource

nevertheless there are 2 ways you can achieve what you want.

void Fetcher_RequestComplete(bool error, string result, int requestsLeft)
{
 if (!error)
 {
    Database.Mods.AddRange(Parser.ParseMods(result));//you can use foreach or write AddRange extension
 }
}

or

void Fetcher_RequestComplete(bool error, string result, int requestsLeft)
{
 if (!error)
 {
    ModGrid.ItemsSource = Parser.ParseMods(result));
 }
}

the cleaner way would be MVVM but thats was not your question :)

Answer 2

Your Mod class needs to implement INotifyPropertyChanged to update the screen appropriately.

尝试

 protected void NotifyPropertyChanged(String info)
