Hi Veselin,

I just tested my sample application with the new internal build, but it's still broken. Here's the code I test with (the XAML basically just contains a checkbox and a RadGridView):

public MainPage()

{

InitializeComponent();

// turn off column virtualization, and don't autogenerate the columns

GridView.EnableColumnVirtualization = false;

GridView.AutoGenerateColumns = false;

// populate the grid with some dummy data

var dummyData = new List<int>();

for (var i = 0; i < 100; i++)

{

dummyData.Add(i);

}

GridView.ItemsSource = dummyData;

// add a column that is not visible by default

GridView.Columns.Add(new GridViewDataColumn { Header = "Int Value", DataMemberBinding = new Binding(), IsVisible = false });

// bind a checkbox to the column's visibility

ColumnVisibleCheckbox.SetBinding(CheckBox.IsCheckedProperty, new Binding("IsVisible"){Mode = BindingMode.TwoWay, Source = GridView.Columns[0]});

}

Checking the checkbox doesn't make the column visible. Let me know if you need me to send you the full solution to test with.
