一、設定內容模板如下
<Style x:Key="ComboBoxToggleButton" TargetType="{x:Type ToggleButton}">
<Setter Property="OverridesDefaultStyle" Value=https://www.cnblogs.com/catzhou/p/"true"/>
</style>
二、前端呼叫(xaml)
<ComboBox Template="{DynamicResource ComboBoxTemplate1}" Background="Red" BorderBrush="Blue" BorderThickness="2" >
<ComboBoxItem IsSelected="True">
<TextBlock Foreground="White">aaa</TextBlock>
</ComboBoxItem>
<ComboBoxItem >
<TextBlock Foreground="Green">bbb</TextBlock>
</ComboBoxItem>
</ComboBox>
三、代碼呼叫（cs）
ComboBox cb = new ComboBox() { Background=Brushes.Red,BorderBrush=Brushes.Blue,BorderThickness=new Thickness(2)};
cb.Items.Add( new TextBox { Text = "aaa" ,Foreground=Brushes.White} );
cb.Items.Add(new TextBox { Text = "bbb", Foreground = Brushes.Green });
cb.SelectedIndex = 0;
cb.Template = Resources["ComboBoxTemplate1"] as ControlTemplate;
