附代码求问各位大神WPF的UI问题..

这是我UI的效果.. 实现方法就是用一Combobox内嵌一Checkbox..
xaml代码如下.. 

<ComboBox Name="cboSales" 

                              Grid.Row="7" 

                              VerticalAlignment="Center"

                              Grid.ColumnSpan="3" 

                              Margin="10,5,0,5"  

                              ItemsSource="{Binding SalesList}" 

                              Text="{Binding DisplaySales}"

                              SelectedIndex="{Binding SalesSelectedIndex,Mode=OneWay}"

                             >

                        <ComboBox.ItemTemplate>

                            <DataTemplate>

                                <CheckBox IsChecked="{Binding SalesChecked}" Content="{Binding DisplaySales}" IsEnabled="{Binding SalesEnabled}" Click="CheckBox_Click"/>

                            </DataTemplate>

                        </ComboBox.ItemTemplate>

                    </ComboBox>

PM说不够美观,要我把下图红框的内容删除/隐藏(反正就是不在UI上显示)


求问各位大大如何才能做出那种效果.. 求代码并详解..
------解决方案--------------------

<DataTemplate>

                    <StackPanel Orientation="Horizontal">

                        <CheckBox Visibility="{Binding CheckVisible}" IsChecked="{Binding SalesChecked}" IsEnabled="{Binding SalesEnabled}" />

                        <TextBlock Text=""/>

                    </StackPanel>

                </DataTemplate>

其实你应该自己也能搞定了
就换成checkbox和textblock
checkbox的显示和不显示 在vm里面搞个property控制下就行了
