How dyanmic to programme TreelistView instead of setting property on xml

[Lior]

Hi,
Currently we adopt the mvvm pattern. there is an issue dynamic column could not set in XAML, We've implemented a dynamic radgrid, but How should we create dynamic RadTreeListview by programme instead of set property on XAML
Currently there are defined in xaml, How we  to move this by dynamically creating column in a custom control.

Thank you in advance.

<telerik:RadTreeListView  ItemsSource="{Binding PhaseSelections, Mode=TwoWay}">
                <telerik:RadTreeListView.Columns>
                    <telerik:GridViewDataColumn DataMemberBinding="{Binding DisplayName, Mode=TwoWay}"/>
                      <telerik:GridViewDataColumn IsReadOnly="True">
                        <telerik:GridViewDataColumn.CellTemplate>
                            <telerik:HierarchicalDataTemplate>
