WPF - 格式化ComboBox的显示项

Question

我已经格式化了一个ComboBox来显示每个项目的详细信息，请不要将设计视为最终，这只是一个例子：

但正如您所看到的，显示的项目（带有箭头的框内）已损坏：

所以我也需要格式化该组件，以便在该框中仅显示Server值。我试图找到正确的元素，甚至设法找到重新格式化整个组合框的方法，但无法为该框内的数据显示添加模板。

如何编辑该容器的数据模板？这是我期望的结果：

<ComboBox x:Name="cboSourceMySql" Grid.Column="1" Margin="5,0,5,0" ItemsSource="{Binding OdbcDataSources, Mode=TwoWay}" Grid.Row="1" >

    <ComboBox.ItemTemplate>
        <DataTemplate>
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition />
                    <RowDefinition />
                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="50" />
                    <ColumnDefinition Width="1*" />
                    <ColumnDefinition Width="50" />
                    <ColumnDefinition Width="1*" />
                </Grid.ColumnDefinitions>
                <Label Content="Server:" Grid.Column="0" Grid.Row="0" />
                <TextBlock Text="{Binding Server}" VerticalAlignment="Center" Grid.Column="1" Grid.Row="0" />
                <Label Content="Driver:" Grid.Column="0" Grid.Row="1" />
                <TextBlock Text="{Binding Driver}" VerticalAlignment="Center" Grid.Column="1" Grid.Row="1" />
            </Grid>
        </DataTemplate>
    </ComboBox.ItemTemplate>
</ComboBox>

从文章WPF Combobox: Different template in textbox and drop-downlist我认为你可以使用以下风格

  <ComboBox 
     x:Name="cboSourceMySql" 
       Grid.Column="1" Margin="5,0,5,0" 
       ItemsSource="{Binding OdbcDataSources, Mode=TwoWay}" 
       Grid.Row="1" >
            <ItemsControl.ItemTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding Server}" />
            </DataTemplate>
        </ItemsControl.ItemTemplate>
        <ComboBox.ItemContainerStyle>
            <Style TargetType="{x:Type ComboBoxItem}">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type ComboBoxItem}">
                            <Border
                                x:Name="Bd"
                                Background="{TemplateBinding Background}"
                                BorderBrush="{TemplateBinding BorderBrush}"
                                BorderThickness="{TemplateBinding BorderThickness}">
                                <StackPanel Orientation="Vertical">
                                    <Label Content="{Binding Server}" />
                                    <Label Content="{Binding Driver}" />
                                </StackPanel>
                            </Border>
                            <ControlTemplate.Triggers>
                                <Trigger Property="IsHighlighted" Value="True">
                                    <Setter TargetName="Bd" Property="Background" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" />
                                    <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}" />
                                </Trigger>
                                <Trigger Property="IsEnabled" Value="False">
                                    <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}" />
                                </Trigger>
                            </ControlTemplate.Triggers>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </ComboBox.ItemContainerStyle>


    </ComboBox>
