Answer 2

假設你知道如何正確地結合，我想是這樣的：

<ComboBox Height="21" HorizontalAlignment="Left" IsEditable="False" IsReadOnly="False" Margin="297,82,0,0" Name="comboBox13" VerticalAlignment="Top" Width="101" SelectedIndex={Binding SelectedIndex, Mode=TwoWay"} > 
    <ComboBoxItem Content="ON" /> 
    <ComboBoxItem Content="OFF" /> 
</ComboBox> 

<Image Height="13" HorizontalAlignment="Left" Margin="284,236,0,0" Name="CB2" Source="/WpfApplication3;component/Images/blankSpacer.gif" Visibility={Binding showcb2, Mode=TwoWay"} /> 
<Image Height="13" HorizontalAlignment="Left" Margin="284,236,0,0" Name="CB3" Source="/WpfApplication3;component/Images/blankSpacer.gif" Visibility={Binding showcb3, Mode=TwoWay"} /> 

然後在視圖模型：

public SelectedIndex{get;set;} 
public Visibility showcb2 
{ 
    get 
    { 
     if (SelectedIndex == 0) 
     { 
      return Visibility.Visible; 
     } 
     return Visibility.Collapsed; 
    }   
} 


public Visibility showcb3 
{ 
    get 
     { 
     if (SelectedIndex == 0) 
     { 
      return Visibility.Visible; 
     } 
     return Visibility.Collapsed; 
    }   
}
