ObservableTable

[Lutoslaw]

Tired of writing dataContext.AddToX(...) in event handlers of WPF controls, I made a simple class which I use instead of ObservableCollection:

class ObservableTable<T> : ObservableCollection<T> where T : class
{
private readonly ObjectQuery<T> _table;
private readonly ObjectContext _context;
public ObservableTable(ObjectQuery<T> table, ObjectContext context) : base(table)
{
_table = table;
_context = context;
}

public ObjectQuery<T> Table
{
    get { return \_table; }
}

protected override void InsertItem(int index, T item)
{
    base.InsertItem(index, item);
    //\_context.AddObject(\_table.CommandText.Substring(1,\_table.CommandText.Length-2), item);
    _\_context.AddObject(((IQueryable) \_table).ElementType.Name, item);_
}
protected override void RemoveItem(int index)
{
    T item = this\[index\];
    base.RemoveItem(index);
    \_context.DeleteObject(item);
}

}

PS. I have asked[^] about the emphasized line in the C# forum;
