Hi,

I am trying to create a dependency property of type List<costumclass><t>>.
This is what I have written so far, but it is not working:

C#

public static readonly DependencyProperty ColumnsProperty = DependencyProperty.Register("Columns",
                                                                                                typeof (
                                                                                                    List<Column<string>>),
                                                                                                typeof (
                                                                                                    ReportBuilderView),
                                                                                                new PropertyMetadata(
                                                                                                    ColumnsChanged));

C#

public List<Column<string>> Columns
        {
            get
            {
                return (List<Column<string>>)this.GetValue(ColumnsProperty);
            }
            set
            {
                this.SetValue(ColumnsProperty, value);
            }
        }

C#

Binding myBinding3 = new Binding("Columns");
            myBinding3.Source = viewModel.Columns;
            myBinding3.Mode = BindingMode.TwoWay;
            BindingOperations.SetBinding(this, ReportBuilderView.ColumnsProperty, myBinding3);

for Columns in the viewModel is an

C#

ObservableCollection<column><string>></string></column>

What's "not working"? Look, there is no such thing for a developers as "not working". There are error messages, exceptions, issue reports...

The binding is not working when it is a collection, means no synchronization between the view and the view model. beside all works fine -means synchronized- when i change the type to string (simple one).
