如何使用DataGrid.Columns與組合框

其複雜因爲即時通過對象UserX做複製列表..我有用戶列表，我想在表中顯示它們。我需要在角色列默認值的組合框將是用戶的當前角色，我需要通過使用組合框來更改此角色的選項，我不知道如何（可能的角色是：管理員，經理和員工）如何使用DataGrid.Columns與組合框

感謝您的幫助。下面是代碼：

XAML

<DataGrid FontSize="20" Name="dgUsers" ItemsSource="{Binding list}" AutoGenerateColumns="False" ScrollViewer.VerticalScrollBarVisibility="Visible"> 
       <DataGrid.Columns> 
        <DataGridTextColumn Header="#" Binding="{Binding Id}" /> 
        <DataGridTextColumn Header="Username" Binding="{Binding Username}" /> 
        <DataGridTextColumn Header="Password" Binding="{Binding Password}" /> 
        <DataGridComboBoxColumn Header="Role" ItemsSource="{Binding Role}" /> 
        <DataGridTemplateColumn Header="Remove"> 
         <DataGridTemplateColumn.CellTemplate> 
          <DataTemplate> 
           <Button Click="ButtonRemove" Content="Remove User"/> 
          </DataTemplate> 
         </DataGridTemplateColumn.CellTemplate> 
        </DataGridTemplateColumn> 

       </DataGrid.Columns> 
      </DataGrid>

 List<User> users = user.getUsersList(); 
     List<Userx> updated = new List<Userx>(); 
     //coping from the list users to list updated. I did it to gete the binding 
     for (int i = 0; i < users.Count; i++) 
      updated.Add(new Userx() { Id = i + 1, Username = users.ElementAt(i).getUsername(), 
                Password = users.ElementAt(i).GetPassword(), 
                Role = users.ElementAt(i).getRole() });    
     dgUsers.ItemsSource = updated; 
    }

請您與嘗試下面的代碼？到ComboBoxSelectedItem屬性添加當前角色。

<Window x:Class="WpfApplication2.MainWindow" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     Title="MainWindow" Height="350" Width="525"> 
    <Grid> 
     <DataGrid FontSize="20" Name="dgUsers" ItemsSource="{Binding list}" AutoGenerateColumns="False" ScrollViewer.VerticalScrollBarVisibility="Visible"> 
      <DataGrid.Columns> 
       <DataGridTextColumn Header="#" Binding="{Binding Id}" /> 
       <DataGridTextColumn Header="Username" Binding="{Binding Username}" /> 
       <DataGridTextColumn Header="Password" Binding="{Binding Password}" /> 
       <DataGridComboBoxColumn Header="Role" ItemsSource="{Binding Role}" SelectedItemBinding="{Binding ComboBoxSelectedItem}" /> 
       <DataGridTemplateColumn Header="Remove"> 
        <DataGridTemplateColumn.CellTemplate> 
         <DataTemplate> 
          <Button Click="ButtonRemove" Content="Remove User"/> 
         </DataTemplate> 
        </DataGridTemplateColumn.CellTemplate> 
       </DataGridTemplateColumn> 

      </DataGrid.Columns> 
     </DataGrid> 
    </Grid> 
</Window>
