如何將ItemsSource綁定到DataGrid時將數據綁定到DataGridTemplateColumn？

我有一個DataGrid，它綁定到一個列表如下。如何將ItemsSource綁定到DataGrid時將數據綁定到DataGridTemplateColumn？

的觀點：

<DataGrid Name="m_dgWorkItems" ItemsSource="{Binding WorkItems}" AutoGenerateColumns="False" CanUserAddRows="False" Margin="12,70,12,12"> 
    <DataGrid.Columns> 
     <DataGridCheckBoxColumn Header="Selected" Binding="{Binding Selected}" /> 
     <DataGridTextColumn Header="Id" Binding="{Binding Id}" IsReadOnly="True" /> 
     <DataGridTextColumn Header="Summary" Binding="{Binding Summary}" IsReadOnly="True" /> 
     <DataGridTextColumn Header="State" Binding="{Binding State}" IsReadOnly="True" /> 
     <DataGridTextColumn Header="Owner" Binding="{Binding Owner}" IsReadOnly="True" /> 
    </DataGrid.Columns> 
</DataGrid>

視圖模型：

public List<WorkItem> WorkItems 
{ 
    get { return m_workItems; } 
    private set { m_workItems = value; RaisePropertyChanged("WorkItems"); } 
} 

public class WorkItem 
{ 
    public bool Selected { get; set; } 

    public string Id { get; set; } 
    public string Summary { get; set; } 
    public string State { get; set; } 
    public string Owner { get; set; } 
    public string Description { get; set; } 
}

我想一個（UN）全選選項添加到頭部，並將其綁定到DataContext的方法。

因此，我改變了觀點：

<DataGrid Name="m_dgWorkItems" ItemsSource="{Binding WorkItems}" AutoGenerateColumns="False" CanUserAddRows="False" Margin="12,70,12,12"> 
    <DataGrid.Columns> 
     <!--<DataGridCheckBoxColumn Header="Selected" Binding="{Binding Selected}" />--> 
     <DataGridTemplateColumn> 
      <DataGridTemplateColumn.Header > 
       <CheckBox Content="Selected" IsChecked="{Binding IsAllChecked, Mode=TwoWay}"></CheckBox> 
      </DataGridTemplateColumn.Header> 
      <DataGridTemplateColumn.CellTemplate > 
       <DataTemplate> 
        <CheckBox IsChecked="{Binding Selected}"/> 
       </DataTemplate> 
      </DataGridTemplateColumn.CellTemplate> 
     </DataGridTemplateColumn> 
     <DataGridTextColumn Header="Id" Binding="{Binding Id}" IsReadOnly="True" /> 
     <DataGridTextColumn Header="Summary" Binding="{Binding Summary}" IsReadOnly="True" /> 
     <DataGridTextColumn Header="State" Binding="{Binding State}" IsReadOnly="True" /> 
     <DataGridTextColumn Header="Owner" Binding="{Binding Owner}" IsReadOnly="True" /> 
    </DataGrid.Columns> 
</DataGrid>

我添加了這個功能視圖模型：

public bool IsAllChecked 
{ 
    get { return m_bIsAllChecked; } 
    set 
    { 
     m_bIsAllChecked = value; 
     foreach (WorkItem workItem in m_workItems) 
      workItem.Selected = value; 
     RaisePropertyChanged("IsAllChecked"); 
    } 
}

然而，該方案從來沒有進入該功能。我認爲這是由於WorkItem屬性不包含IsAllChecked屬性。我不知道如何指定綁定應在的DataContext被應用，而不是當前的ItemsSource =「{結合工作項}」
