casella combinata personalizzata in wpf Applicazione

Question

Im new to WPF Application. Devo personalizzare la mia casella combinata come questa immagine.

Ho provato questo esempio http://www.eidias.com/Blog/2012/2/20/customizing-wpf-combo-box-style

<Window x:Class="win.Window1" 
     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
     Title="Window1" Height="300" Width="300" Background="Red"> 
    <Window.Resources> 
     <ControlTemplate x:Key="CustomToggleButton" TargetType="ToggleButton"> 
      <Grid> 
       <Border Name="Border" /> 
       <Border Name="SmallBorder" /> 
       <Path Name="Arrow" /> 
      </Grid> 
     </ControlTemplate> 
     <Style TargetType="{x:Type ComboBoxItem}"> 
      <Setter Property="FrameworkElement.OverridesDefaultStyle" Value="True" /> 
      <Setter Property="Control.Template"> 
       <Setter.Value> 
        <ControlTemplate TargetType="{x:Type ComboBoxItem}"> 
         <Border> 
          <ContentPresenter /> 
         </Border> 
        </ControlTemplate> 
       </Setter.Value> 
      </Setter> 
     </Style> 
     <Style TargetType="{x:Type ComboBox}"> 
      <Setter Property="FrameworkElement.OverridesDefaultStyle" Value="True" /> 
      <Setter Property="Control.Template"> 
       <Setter.Value> 
        <ControlTemplate TargetType="ComboBox"> 
         <Grid> 
          <ToggleButton Template="{StaticResource CustomToggleButton}" /> 
          <ContentPresenter /> 
          <TextBox /> 
          <Popup> 
           <Grid> 
            <Border> 
             <ScrollViewer> 
              <ItemsPresenter /> 
             </ScrollViewer> 
            </Border> 
           </Grid> 
          </Popup> 
         </Grid> 
        </ControlTemplate> 
       </Setter.Value> 
      </Setter> 
     </Style> 
    </Window.Resources> 
    <Grid> 
     <ComboBox Grid.Column="1" Height="40" Width="200" > 
      <ComboBoxItem Name="item1">item1</ComboBoxItem> 
      <ComboBoxItem Name="item2">item2</ComboBoxItem> 
      <ComboBoxItem Name="item3">item3</ComboBoxItem> 
     </ComboBox> 
    </Grid> 
</Window> 

Questa uscita opere come textbox.Please mi aiuti ragazzi!

Mi è piaciuto anche il formato e ho deciso di riprodurlo. Si prega di trovare il XAML qui sotto. Speranza che aiuta qualcuno ...

controlla questo link:

http://www.eidias.com/Blog/2012/2/20/customizing-wpf-combo-box-style

Questo è un blog con il codice di esempio su come fare un Combobox personalizzato. La combobox personalizzata che sta creando assomiglia molto a quella che ti serve. Quindi penso che questo ti sarà molto utile.

Ecco uno stile completo per WPF ComboBox. È anche facile da personalizzare.

http://www.wpfhelper.com/index.php/styles-in-wpf/combobox/15-combobox-style-in-wpf

I codici sono abbastanza lunga quindi non posterò tutti qui. Tuttavia, ecco lo stile ComboBox di base:

<Style TargetType="{x:Type ComboBox">   
    <Setter Property="Foreground" Value="Gray" /> 
    <Setter Property="BorderBrush" Value="Gray" />

    <Setter Property="OverridesDefaultStyle" Value="true"/> 
    <Setter Property="ScrollViewer.HorizontalScrollBarVisibility" Value="Auto"/> 
    <Setter Property="ScrollViewer.VerticalScrollBarVisibility" Value="Auto"/> 
    <Setter Property="ScrollViewer.CanContentScroll" Value="true"/>
