silverlight中的datagrid如何内嵌combobox

<data:DataGridTemplateColumn Header="进度" Width="50">
    <data:DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <ComboBox ItemsSource="{Binding something}"></ComboBox>
        </DataTemplate>
    </data:DataGridTemplateColumn.CellTemplate>
</data:DataGridTemplateColumn>
