在代碼中為內聯xaml設置數據源

Question

請看下面的代碼。 我正在嘗試使用Checkbox模板動態添加數據列。 如您所見，我還使用數據上下文代理來綁定復選框的IsChecked值。 但是，在這種情況下，我無法弄清楚如何設置綁定源。

GridViewDataColumn dataColumn = new GridViewDataColumn(); 
                // setup the header
                dataColumn.Header = "sample"; 
                dataColumn.HeaderTextAlignment = TextAlignment.Center;
                dataColumn.IsGroupable = false;
                dataColumn.IsFilterable = true;
                dataColumn.IsSortable = false;
                //// set the width

                dataColumn.MinWidth = 100;
                // setup the binding


                DataContextProxy dcProxy = new DataContextProxy();
                dcProxy.Name = "proxy";
                dcProxy.DataContext = this.DataContext;

            string checkBoxTemplate = string.Format(@"<DataTemplate xmlns=""http://schemas.microsoft.com/winfx/2006/xaml/presentation"" 
                                                        xmlns:x=""http://schemas.microsoft.com/winfx/2006/xaml"">
                                                        <CheckBox  IsChecked=""{{Binding Path=DataSource.IsVersionIncluded,Mode=TwoWay}}"" IsThreeState=""False""/>
                                                        </DataTemplate>", dcProxy.DataSource);
            dataColumn.CellTemplate = (DataTemplate)XamlReader.Load(checkBoxTemplate);

            Binding binding = new Binding();


            binding.Source = dcProxy;

            binding.Path = new PropertyPath("DataSource.IsVersionIncluded");
            binding.Mode = BindingMode.TwoWay;
            binding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;

            dataColumn.DataMemberBinding = binding;

            //add column to TreeListView
            radTreeListView.Columns.Add(dataColumn);

這是ViewModel中的布爾屬性，一旦用戶選中/取消選中當前未發生的網格單元格中的復選框，我打算點擊該屬性。

private bool _isVersionIncluded = false;
    public bool IsVersionIncluded
    {
        get { return _isVersionIncluded; }
        set
        {
            _isVersionIncluded = value;

        }
    }

請有人能告訴我我在這里想念什么嗎？ 非常感謝。

您沒有在媒體資源中使用INotifyPropertyChanged接口

private bool _isVersionIncluded = false;
public bool IsVersionIncluded
{
    get { return _isVersionIncluded; }
    set
    {
        _isVersionIncluded = value;

    }
}
